# Abstract
Scan containers
Trivy (`tri` pronounced like **tri**gger, `vy` pronounced like en**vy**) is a comprehensive security scanner. It is reliable, fast, extremely easy to use, and it works wherever you need it.
# Features
Trivy has different *scanners* that look for different security issues, and different *targets* where it can find those issues.
# Installation
Targets:
- Container Image
- Filesystem
- Git repository (remote)
- Kubernetes cluster or resource
## RHEL/CentOS
Scanners:
- OS packages and software dependencies in use (SBOM)
- Known vulnerabilities (CVEs)
- IaC misconfigurations
- Sensitive information and secrets
Add repository setting to `/etc/yum.repos.d`.
Much more scanners and targets are coming up. Missing something? Let us know!

## Wrong detection
Trivy depends on [multiple data sources](https://aquasecurity.github.io/trivy/latest/docs/vulnerability/detection/data-source/).
Sometime these databases contain mistakes.
If Trivy can't detect any CVE-IDs or shows false positive result, at first please follow the next steps:
1. Run Trivy with `-f json` that shows data sources.
2. According to the shown data source, make sure that the security advisory in the data source is correct.
If the data source is correct and Trivy shows wrong results, please raise an issue on Trivy.
### GitHub Advisory Database
Visit [here](https://github.com/advisories) and search CVE-ID.
If you find a problem, it'll be nice to fix it: [How to contribute to a GitHub security advisory](https://github.blog/2022-02-22-github-advisory-database-now-open-to-community-contributions/)

It's up to reviewer to mark it resolved (in case if suggested fix addresses problem properly). PRs with unresolved issues should not be merged (even if the comment is unclear or requires no action from your side).
1. Please include a comment with the results before and after your change.
1. Your PR is more likely to be accepted if it includes tests (We have not historically been very strict about tests, but we would like to improve this!).
1. If your PR affects the user experience in some way, please update the README.md and the CLI help accordingly.
### Title
It is not that strict, but we use the title conventions in this repository.
Each commit message doesn't have to follow the conventions as long as it is clear and descriptive since it will be squashed and merged.
#### Format of the title
```
<type>(<scope>): <subject>
```
The `type` and `scope` should always be lowercase as shown below.
**Allowed `<type>` values:**
- **feat** for a new feature for the user, not a new feature for build script. Such commit will trigger a release bumping a MINOR version.

- **perf** for performance improvements. Such commit will trigger a release bumping a PATCH version.
- **docs** for changes to the documentation.
- **style** for formatting changes, missing semicolons, etc.
- **refactor** for refactoring production code, e.g. renaming a variable.
- **test** for adding missing tests, refactoring tests; no production code change.
- **build** for updating build configuration, development tools or other changes irrelevant to the user.
- **chore** for updates that do not apply to the above, such as dependency updates.

## Understand where your pull request belongs
Trivy is composed of several repositories that work together:
- [Trivy](https://github.com/aquasecurity/trivy) is the client-side, user-facing, command line tool.
- [vuln-list](https://github.com/aquasecurity/vuln-list) is a vulnerabilities database, aggregated from different sources, and normalized for easy consumption. Think of this as the "server" side of the trivy command line tool. **There should be no pull requests to this repo**
- [vuln-list-update](https://github.com/aquasecurity/vuln-list-update) is the code that maintains the vuln-list database.
- [trivy-db](https://github.com/aquasecurity/trivy-db) maintains the vulnerability database pulled by Trivy CLI.
- [go-dep-parser](https://github.com/aquasecurity/go-dep-parser) is a library for parsing lock files such as package-lock.json and Gemfile.lock.

# Overview
We use two labels [help wanted](#help-wanted) and [good first
issue](#good-first-issue) to identify issues that have been specially groomed
for new contributors. The `good first issue` label is a subset of `help wanted`
label, indicating that members have committed to providing extra assistance for
new contributors. All `good first issue` items also have the `help wanted`
label.
## Help Wanted
Items marked with the `help wanted` label need to ensure that they are:
- **Low Barrier to Entry**
It should be tractable for new contributors. Documentation on how that type of
change should be made should already exist.
- **Clear Task**
The task is agreed upon and does not require further discussions in the
community. Call out if that area of code is untested and requires new
fixtures.
API / CLI behavior is decided and included in the OP issue, for example: "The
new command syntax is `trivy --format yaml IMAGE_NAME`"_ with
expected validations called out.
- **Goldilocks priority**
Not too high that a core contributor should do it, but not too low that it
isn't useful enough for a core contributor to spend time to review it, answer
questions, help get it into a release, etc.
- **Up-To-Date**
Often these issues become obsolete and have already been done, are no longer
desired, no longer make sense, have changed priority or difficulty , etc.
## Good First Issue
Items marked with the `good first issue` label are intended for _first-time
contributors_. It indicates that members will keep an eye out for these pull
requests and shepherd it through our processes.
These items need to ensure that they follow the guidelines for `help wanted`
labels (above) in addition to meeting the following criteria:
- **No Barrier to Entry**
The task is something that a new contributor can tackle without advanced
setup, or domain knowledge.
- **Solution Explained**
The recommended solution is clearly described in the issue.
- **Provides Context**
If background knowledge is required, this should be explicitly mentioned and a
list of suggested readings included.
- **Gives Examples**
Link to examples of similar implementations so new contributors have a
reference guide for their changes.
- **Identifies Relevant Code**
The relevant code and tests to be changed should be linked in the issue.
- **Ready to Test**
There should be existing tests that can be modified, or existing test cases
fit to be copied. If the area of code doesn't have tests, before labeling the
issue, add a test fixture. This prep often makes a great `help wanted` task!

# Triage
Triage is an important part of maintaining the health of the trivy repo.
A well organized repo allows maintainers to prioritize feature requests, fix bugs, and respond to users facing difficulty with the tool as quickly as possible.
Triage includes:
- Labeling issues
- Responding to issues
- Closing issues
# Daily Triage
Daily triage has two goals:
1. Responsiveness for new issues
1. Responsiveness when explicitly requested information was provided
It covers:
1. Issues without a `kind/` or `triage/` label
1. Issues without a `priority/` label
1. `triage/needs-information` issues which the user has followed up on, and now require a response.
## Categorization
The most important level of categorizing the issue is defining what type it is.
We typically want at least one of the following labels on every issue, and some issues may fall into multiple categories:
- `triage/support` - The default for most incoming issues
- `kind/bug` - When its a bug or we arent delivering the best user experience
Other possibilities:
- `kind/feature`- Identify new feature requests
- `kind/testing` - Update or fix unit/integration tests
- `kind/cleanup` - Cleaning up/refactoring the codebase
- `kind/documentation` - Updates or additions to trivy documentation
If the issue is specific to a driver for OS packages or libraries:
**co/[driver for OS packages]**
- `co/alpine`
- `co/amazon`
- `co/debian`
- `co/oracle`
- `co/photon`
- `co/redhat`
- `co/suse`
- `co/ubuntu`
**co/[driver for libraries of programming languages]**
- `co/bundler`
- `co/cargo`
- `co/composer`
- `co/npm`
- `co/yarn`
- `co/pipenv`
- `co/poetry`
**Help wanted?**
`Good First Issue` - bug has a proposed solution, can be implemented w/o further discussion.
`Help wanted` - if the bug could use help from a contributor
## Prioritization
If the issue is not `triage/support`, it needs a priority label.
`priority/critical-urgent` - someones top priority ASAP, such as security issue, user-visible bug, or build breakage. Rarely used.
`priority/important-soon`: in time for the next two releases. It should be attached to a milestone.
`priority/important-longterm`: 2-4 releases from now
`priority/backlog`: agreed that this would be good to have, but no one is available at the moment. Consider tagging as `help wanted`
`priority/awaiting-more-evidence`: may be useful, but there is not yet enough support.
# Weekly Triage
Weekly triage has three goals:
1. Catching up on unresponded issues
1. Reviewing and closing PRs
1. Closing stale issues
## Post-Release Triage
Post-release triage occurs after a major release (around every 4-6 weeks).
It focuses on:
1. Closing bugs that have been resolved by the release
1. Reprioritizing bugs that have not been resolved by the release
1. Letting users know if we believe that there is still an issue
This includes reviewing:
1. Every issue that hasnt been touched in the last 2 days
1. Re-evaluation of long-term issues
1. Re-evaluation of short-term issues
## Responding to Issues
### Needs More Information
A sample response to ask for more info:
> I dont yet have a clear way to replicate this issue. Do you mind adding some additional details. Here is additional information that would be helpful:
>
> \* The exact `trivy` command line used
>
> \* The exact image you want to scan
>
> \* The full output of the `trivy` command, preferably with `--debug` for extra logging.
>
>
> Thank you for sharing your experience!
Then: Label with `triage/needs-information`.
### Issue might be resolved
If you think a release may have resolved an issue, ask the author to see if their issue has been resolved:
> Could you please check to see if trivy <x> addresses this issue? We've made some changes with how this is handled, and improved the trivy logs output to help us debug tricky cases like this.
Then: Label with `triage/needs-information`.
## Closing with Care
Issues typically need to be closed for the following reasons:
- The issue has been addressed
- The issue is a duplicate of an existing issue
- There has been a lack of information over a long period of time
In any of these situations, we aim to be kind when closing the issue, and offer the author action items should they need to reopen their issue or still require a solution.
Samples responses for these situations include:
### Issue has been addressed
>@author: I believe this issue is now addressed by trivy v1.0.0, as it <reason>. If you still see this issue with trivy v1.0 or higher, please reopen this issue.
>
>Thank you for reporting this issue!
Then: Close the issue
### Duplicate Issue
>This issue appears to be a duplicate of #X, do you mind if we move the conversation there?
>
>This way we can centralize the content relating to the issue. If you feel that this issue is not in fact a duplicate, please re-open it. If you have additional information to share, please add it to the new issue.
>
>Thank you for reporting this!
Then: Label with `triage/duplicate` and close the issue.
### Lack of Information
If an issue hasn't been active for more than four weeks, and the author has been pinged at least once, then the issue can be closed.
>Hey @author -- hopefully it's OK if I close this - there wasn't enough information to make it actionable, and some time has already passed. If you are able to provide additional details, you may reopen it at any point.
>
>Here is additional information that may be helpful to us:
>
>\* Whether the issue occurs with the latest trivy release
>
>\* The exact `trivy` command line used
>
>\* The exact image you want to scan
>
>\* The full output of the `trivy` command, preferably with `--debug` for extra logging.
>
>
>Thank you for sharing your experience!
Then: Close the issue.
## Help Wanted issues
We use two labels [help wanted](https://github.com/aquasecurity/trivy/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
and [good first issue](https://github.com/aquasecurity/trivy/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
to identify issues that have been specially groomed for new contributors.
We have specific [guidelines](/docs/community/maintainer/help-wanted.md)
for how to use these labels. If you see an issue that satisfies these
guidelines, you can add the `help wanted` label and the `good first issue` label.
Please note that adding the `good first issue` label must also
add the `help wanted` label.
If an issue has these labels but does not satisfy the guidelines, please
ask for more details to be added to the issue or remove the labels.

# Air-Gapped Environment
Trivy can be used in air-gapped environments. Note that an allowlist is [here][allowlist].
## Air-Gapped Environment for vulnerabilities
### Download the vulnerability database
=== "Trivy"
```
TRIVY_TEMP_DIR=$(mktemp -d)
trivy --cache-dir $TRIVY_TEMP_DIR image --download-db-only
tar -cf ./db.tar.gz -C $TRIVY_TEMP_DIR/db metadata.json trivy.db
rm -rf $TRIVY_TEMP_DIR
```
=== "oras >= v0.13.0"
At first, you need to download the vulnerability database for use in air-gapped environments.
Please follow [oras installation instruction][oras].
Download `db.tar.gz`:
```
$ oras pull ghcr.io/aquasecurity/trivy-db:2
```
=== "oras < v0.13.0"
At first, you need to download the vulnerability database for use in air-gapped environments.
Please follow [oras installation instruction][oras].
Download `db.tar.gz`:
```
$ oras pull -a ghcr.io/aquasecurity/trivy-db:2
```
### Transfer the DB file into the air-gapped environment
The way of transfer depends on the environment.
```
$ rsync -av -e ssh /path/to/db.tar.gz [user]@[host]:dst
```
### Put the DB file in Trivy's cache directory
You have to know where to put the DB file. The following command shows the default cache directory.
```
$ ssh user@host
$ trivy -h | grep cache
--cache-dir value cache directory (default: "/home/myuser/.cache/trivy") [$TRIVY_CACHE_DIR]
```
Put the DB file in the cache directory + `/db`.
```
$ mkdir -p /home/myuser/.cache/trivy/db
$ cd /home/myuser/.cache/trivy/db
$ tar xvf /path/to/db.tar.gz -C /home/myuser/.cache/trivy/db
x trivy.db
x metadata.json
$ rm /path/to/db.tar.gz
```
In an air-gapped environment it is your responsibility to update the Trivy database on a regular basis, so that the scanner can detect recently-identified vulnerabilities.
### Run Trivy with `--skip-update` and `--offline-scan` option
In an air-gapped environment, specify `--skip-update` so that Trivy doesn't attempt to download the latest database file.
In addition, if you want to scan Java dependencies such as JAR and pom.xml, you need to specify `--offline-scan` since Trivy tries to issue API requests for scanning Java applications by default.
```
$ trivy image --skip-update --offline-scan alpine:3.12
```
## Air-Gapped Environment for misconfigurations
No special measures are required to detect misconfigurations in an air-gapped environment.
### Run Trivy with `--skip-policy-update` option
In an air-gapped environment, specify `--skip-policy-update` so that Trivy doesn't attempt to download the latest misconfiguration policies.
```
$ trivy conf --skip-policy-update /path/to/conf
```

# Embed in Dockerfile
Scan your image as part of the build process by embedding Trivy in the
Dockerfile. This approach can be used to update Dockerfiles currently using
Aquas [Microscanner][microscanner].
```bash
$ cat Dockerfile
FROM alpine:3.7
RUN apk add curl \
&& curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin \
&& trivy rootfs --exit-code 1 --no-progress /
$ docker build -t vulnerable-image .
```
Alternatively you can use Trivy in a multistage build. Thus avoiding the
insecure `curl | sh`. Also the image is not changed.
```bash
[...]
# Run vulnerability scan on build image
FROM build AS vulnscan
COPY --from=aquasec/trivy:latest /usr/local/bin/trivy /usr/local/bin/trivy

# Modules
!!! warning "EXPERIMENTAL"
This feature might change without preserving backwards compatibility.
Trivy provides a module feature to allow others to extend the Trivy CLI without the need to change the Trivy code base.
It changes the behavior during scanning by WebAssembly.
## Overview
Trivy modules are add-on tools that integrate seamlessly with Trivy.
They provide a way to extend the core feature set of Trivy, but without updating the Trivy binary.
- They can be added and removed from a Trivy installation without impacting the core Trivy tool.
- They can be written in any programming language supporting WebAssembly.
- It supports only [TinyGo][tinygo] at the moment.
You can write your own detection logic.
- Evaluate complex vulnerability conditions like [Spring4Shell][spring4shell]
- Detect a shell script communicating with malicious domains
- Detect malicious python install script (setup.py)
- Even detect misconfigurations in WordPress setting
- etc.
Then, you can update the scan result however you want.
- Change a severity
- Remove a vulnerability
- Add a new vulnerability
- etc.
Modules should be distributed in OCI registries like GitHub Container Registry.
!!! warning
WebAssembly doesn't allow file access and network access by default.
Modules can read required files only, but cannot overwrite them.
WebAssembly is sandboxed and secure by design, but Trivy modules available in public are not audited for security.
You should install and run third-party modules at your own risk even though
Under the hood Trivy leverages [wazero][wazero] to run WebAssembly modules without CGO.
## Installing a Module
A module can be installed using the `trivy module install` command.
This command takes an url. It will download the module and install it in the module cache.
Trivy adheres to the XDG specification, so the location depends on whether XDG_DATA_HOME is set.
Trivy will now search XDG_DATA_HOME for the location of the Trivy modules cache.
The preference order is as follows:
- XDG_DATA_HOME if set and .trivy/plugins exists within the XDG_DATA_HOME dir
- $HOME/.trivy/plugins
For example, to download the WebAssembly module, you can execute the following command:
```bash
$ trivy module install ghcr.io/aquasecurity/trivy-module-spring4shell
```
## Using Modules
Once the module is installed, Trivy will load all available modules in the cache on the start of the next Trivy execution.
The modules may inject custom logic into scanning and change the result.
You can run Trivy as usual and modules are loaded automatically.
You will see the log messages about WASM modules.
```shell
$ trivy image ghcr.io/aquasecurity/trivy-test-images:spring4shell-jre8

...(snip)...
```
In the above example, the Spring4Shell module changed the severity from CRITICAL to LOW because the application doesn't satisfy one of conditions.
## Uninstalling Modules
Specify a module repository with `trivy module uninstall` command.
```bash
$ trivy module uninstall ghcr.io/aquasecurity/trivy-module-spring4shell
```
## Building Modules
It supports TinyGo only at the moment.
### TinyGo
Trivy provides Go SDK including three interfaces.
Your own module needs to implement either or both `Analyzer` and `PostScanner` in addition to `Module`.
```go
type Module interface {
Version() int
Name() string
}
type Analyzer interface {
RequiredFiles() []string
Analyze(filePath string) (*serialize.AnalysisResult, error)
}
type PostScanner interface {
PostScanSpec() serialize.PostScanSpec
PostScan(serialize.Results) (serialize.Results, error)
}
```
In the following tutorial, it creates a WordPress module that detects a WordPress version and a critical vulnerability accordingly.
!!! tips
You can use logging functions such as `Debug` and `Info` for debugging.
See [examples](#examples) for the detail.
#### Initialize your module
Replace the repository name with yours.
```
$ go mod init github.com/aquasecurity/trivy-module-wordpress
```
#### Module interface
`Version()` returns your module version and should be incremented after updates.
`Name()` returns your module name.
```go
package main
const (
version = 1
name = "wordpress-module"
)
type WordpressModule struct{
// Cannot define fields as modules can't keep state.
}
func (WordpressModule) Version() int {
return version
}
func (WordpressModule) Name() string {
return name
}
```
!!! info
A struct cannot have any fields. Each method invocation is performed in different states.
#### Analyzer interface
If you implement the `Analyzer` interface, `Analyze` method is called when the file path is matched to file patterns returned by `RequiredFiles()`.
A file pattern must be a regular expression. The syntax detail is [here][regexp].
`Analyze` takes the matched file path, then the file can be opened by `os.Open()`.
```go
const typeWPVersion = "wordpress-version"
func (WordpressModule) RequiredFiles() []string {
return []string{
`wp-includes\/version.php`,
}
}
func (WordpressModule) Analyze(filePath string) (*serialize.AnalysisResult, error) {
f, err := os.Open(filePath) // e.g. filePath: /usr/src/wordpress/wp-includes/version.php
if err != nil {
return nil, err
}
defer f.Close()
var wpVersion string
scanner := bufio.NewScanner(f)
for scanner.Scan() {
line := scanner.Text()
if !strings.HasPrefix(line, "$wp_version=") {
continue
}
ss := strings.Split(line, "=")
if len(ss) != 2 {
return nil, fmt.Errorf("invalid wordpress version: %s", line)
}
// NOTE: it is an example; you actually need to handle comments, etc
ss[1] = strings.TrimSpace(ss[1])
wpVersion = strings.Trim(ss[1], `";`)
}
if err = scanner.Err(); err != nil {
return nil, err
}
return &serialize.AnalysisResult{
CustomResources: []serialize.CustomResource{
{
Type: typeWPVersion,
FilePath: filePath,
Data: wpVersion,
},
},
}, nil
}
```
!!! tips
Trivy caches analysis results according to the module version.
We'd recommend cleaning the cache or changing the module version every time you update `Analyzer`.
#### PostScanner interface
`PostScan` is called after scanning and takes the scan result as an argument from Trivy.
In post scanning, your module can perform one of three actions:
- Insert
- Add a new security finding
- e.g. Add a new vulnerability and misconfiguration
- Update
- Update the detected vulnerability and misconfiguration
- e.g. Change a severity
- Delete
- Delete the detected vulnerability and misconfiguration
- e.g. Remove Spring4Shell because it is not actually affected.
`PostScanSpec()` returns which action the module does.
If it is `Update` or `Delete`, it also needs to return IDs such as CVE-ID and misconfiguration ID, which your module wants to update or delete.
`serialize.Results` contains the filtered results matching IDs you specified.
Also, it includes `CustomResources` with the values your `Analyze` returns, so you can modify the scan result according to the custom resources.
```go
func (WordpressModule) PostScanSpec() serialize.PostScanSpec {
return serialize.PostScanSpec{
Action: api.ActionInsert, // Add new vulnerabilities
}
}
func (WordpressModule) PostScan(results serialize.Results) (serialize.Results, error) {
// e.g. results
// [
// {
// "Target": "",
// "Class": "custom",
// "CustomResources": [
// {
// "Type": "wordpress-version",
// "FilePath": "/usr/src/wordpress/wp-includes/version.php",
// "Layer": {
// "DiffID": "sha256:057649e61046e02c975b84557c03c6cca095b8c9accd3bd20eb4e432f7aec887"
// },
// "Data": "5.7.1"
// }
// ]
// }
// ]
var wpVersion int
for _, result := range results {
if result.Class != types.ClassCustom {
continue
}
for _, c := range result.CustomResources {
if c.Type != typeWPVersion {
continue
}
wpVersion = c.Data.(string)
wasm.Info(fmt.Sprintf("WordPress Version: %s", wpVersion))
...snip...
if affectedVersion.Check(ver) {
vulnerable = true
}
break
}
}
if vulnerable {
// Add CVE-2020-36326
results = append(results, serialize.Result{
Target: wpPath,
Class: types.ClassLangPkg,
Type: "wordpress",
Vulnerabilities: []types.DetectedVulnerability {
{
VulnerabilityID: "CVE-2020-36326",
PkgName: "wordpress",
InstalledVersion: wpVersion,
FixedVersion: "5.7.2",
Vulnerability: dbTypes.Vulnerability{
Title: "PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname.",
Severity: "CRITICAL",
},
},
},
})
}
return results, nil
}
```
The new vulnerability will be added to the scan results.
This example shows how the module inserts a new finding.
If you are interested in `Update`, you can see an example of [Spring4Shell][trivy-module-spring4shell].
In the `Delete` action, `PostScan` needs to return results you want to delete.
If `PostScan` returns an empty, Trivy will not delete anything.
#### Build
Follow [the install guide][tinygo-installation] and install TinyGo.
```bash
$ tinygo build -o wordpress.wasm -scheduler=none -target=wasi --no-debug wordpress.go
```
Put the built binary to the module directory that is under the home directory by default.
```bash
$ mkdir -p ~/.trivy/modules
$ cp spring4shell.wasm ~/.trivy/modules
```
## Distribute Your Module
You can distribute your own module in OCI registries. Please follow [the oras installation instruction][oras].
```bash
oras push ghcr.io/aquasecurity/trivy-module-wordpress:latest wordpress.wasm:application/vnd.module.wasm.content.layer.v1+wasm

# Plugins
Trivy provides a plugin feature to allow others to extend the Trivy CLI without the need to change the Trivycode base.
This plugin system was inspired by the plugin system used in [kubectl][kubectl], [Helm][helm], and [Conftest][conftest].
## Overview
Trivy plugins are add-on tools that integrate seamlessly with Trivy.
They provide a way to extend the core feature set of Trivy, but without requiring every new feature to be written in Go and added to the core tool.
- They can be added and removed from a Trivy installation without impacting the core Trivy tool.
- They can be written in any programming language.
- They integrate with Trivy, and will show up in Trivy help and subcommands.
!!! warning
Trivy plugins available in public are not audited for security.
You should install and run third-party plugins at your own risk, since they are arbitrary programs running on your machine.
## Installing a Plugin
A plugin can be installed using the `trivy plugin install` command.
This command takes a url and will download the plugin and install it in the plugin cache.
Trivy adheres to the XDG specification, so the location depends on whether XDG_DATA_HOME is set.
Trivy will now search XDG_DATA_HOME for the location of the Trivy plugins cache.
The preference order is as follows:
- XDG_DATA_HOME if set and .trivy/plugins exists within the XDG_DATA_HOME dir
- ~/.trivy/plugins
Under the hood Trivy leverages [go-getter][go-getter] to download plugins.
This means the following protocols are supported for downloading plugins:
- OCI Registries
- Local Files
- Git
- HTTP/HTTPS
- Mercurial
- Amazon S3
- Google Cloud Storage
For example, to download the Kubernetes Trivy plugin you can execute the following command:
```bash
$ trivy plugin install github.com/aquasecurity/trivy-plugin-kubectl
```
## Using Plugins
Once the plugin is installed, Trivy will load all available plugins in the cache on the start of the next Trivy execution.
A plugin will be made in the Trivy CLI based on the plugin name.
To display all plugins, you can list them by `trivy --help`
```bash
$ trivy --help
NAME:
trivy - A simple and comprehensive vulnerability scanner for containers
USAGE:
trivy [global options] command [command options] target
VERSION:
dev
COMMANDS:
image, i scan an image
filesystem, fs scan local filesystem
repository, repo scan remote repository
client, c client mode
server, s server mode
plugin, p manage plugins
kubectl scan kubectl resources
help, h Shows a list of commands or help for one command
```
As shown above, `kubectl` subcommand exists in the `COMMANDS` section.
To call the kubectl plugin and scan existing Kubernetes deployments, you can execute the following command:
```
$ trivy kubectl deployment <deployment-id> -- --ignore-unfixed --severity CRITICAL
```
Internally the kubectl plugin calls the kubectl binary to fetch information about that deployment and passes the using images to Trivy.
You can see the detail [here][trivy-plugin-kubectl].
If you want to omit even the subcommand, you can use `TRIVY_RUN_AS_PLUGIN` environment variable.
```bash
$ TRIVY_RUN_AS_PLUGIN=kubectl trivy job your-job -- --format json
```
## Installing and Running Plugins on the fly
`trivy plugin run` installs a plugin and runs it on the fly.
If the plugin is already present in the cache, the installation is skipped.
```bash
trivy plugin run github.com/aquasecurity/trivy-plugin-kubectl pod your-pod -- --exit-code 1
```
## Uninstalling Plugins
Specify a plugin name with `trivy plugin uninstall` command.
```bash
$ trivy plugin uninstall kubectl
```
## Building Plugins
Each plugin has a top-level directory, and then a plugin.yaml file.
```bash
your-plugin/
|
|- plugin.yaml
|- your-plugin.sh
```
In the example above, the plugin is contained inside of a directory named `your-plugin`.
It has two files: plugin.yaml (required) and an executable script, your-plugin.sh (optional).
The core of a plugin is a simple YAML file named plugin.yaml.
Here is an example YAML of trivy-plugin-kubectl plugin that adds support for Kubernetes scanning.
```yaml
name: "kubectl"
repository: github.com/aquasecurity/trivy-plugin-kubectl
version: "0.1.0"
usage: scan kubectl resources
description: |-
A Trivy plugin that scans the images of a kubernetes resource.
Usage: trivy kubectl TYPE[.VERSION][.GROUP] NAME
platforms:
- selector: # optional
os: darwin
arch: amd64
uri: ./trivy-kubectl # where the execution file is (local file, http, git, etc.)
bin: ./trivy-kubectl # path to the execution file
- selector: # optional
os: linux
arch: amd64
uri: https://github.com/aquasecurity/trivy-plugin-kubectl/releases/download/v0.1.0/trivy-kubectl.tar.gz
bin: ./trivy-kubectl
```
The `plugin.yaml` field should contain the following information:
- name: The name of the plugin. This also determines how the plugin will be made available in the Trivy CLI. For example, if the plugin is named kubectl, you can call the plugin with `trivy kubectl`. (required)
- version: The version of the plugin. (required)
- usage: A short usage description. (required)
- description: A long description of the plugin. This is where you could provide a helpful documentation of your plugin. (required)
- platforms: (required)
- selector: The OS/Architecture specific variations of a execution file. (optional)
- os: OS information based on GOOS (linux, darwin, etc.) (optional)
- arch: The architecture information based on GOARCH (amd64, arm64, etc.) (optional)
- uri: Where the executable file is. Relative path from the root directory of the plugin or remote URL such as HTTP and S3. (required)
- bin: Which file to call when the plugin is executed. Relative path from the root directory of the plugin. (required)
The following rules will apply in deciding which platform to select:
- If both `os` and `arch` under `selector` match the current platform, search will stop and the platform will be used.
- If `selector` is not present, the platform will be used.
- If `os` matches and there is no more specific `arch` match, the platform will be used.
- If no `platform` match is found, Trivy will exit with an error.
After determining platform, Trivy will download the execution file from `uri` and store it in the plugin cache.
When the plugin is called via Trivy CLI, `bin` command will be executed.
The plugin is responsible for handling flags and arguments. Any arguments are passed to the plugin from the `trivy` command.

# Scan SBOM attestation in Rekor
!!! warning "EXPERIMENTAL"
This feature might change without preserving backwards compatibility.
## Container images
Trivy can retrieve SBOM attestation of the specified container image in the [Rekor][rekor] instance and scan it for vulnerabilities.
### Prerequisites
1. SBOM attestation stored in Rekor
- See [the "Keyless signing" section][sbom-attest] if you want to upload your SBOM attestation to Rekor.
### Scanning
You need to pass `--sbom-sources rekor` so that Trivy will look for SBOM attestation in Rekor.
!!! note
`--sbom-sources` can be used only with `trivy image` at the moment.
```bash
$ trivy image --sbom-sources rekor otms61/alpine:3.7.3 [~/src/github.com/aquasecurity/trivy]

If you have your own Rekor instance, you can specify the URL via `--rekor-url`.
```bash
$ trivy image --sbom-sources rekor --rekor-url https://my-rekor.dev otms61/alpine:3.7.3
```
## Non-packaged binaries
Trivy can retrieve SBOM attestation of non-packaged binaries in the [Rekor][rekor] instance and scan it for vulnerabilities.
### Prerequisites
1. SBOM attestation stored in Rekor
- See [the "Keyless signing" section][sbom-attest] if you want to upload your SBOM attestation to Rekor.
Cosign currently does not support keyless signing for blob attestation, so use our plugin at the moment.
This example uses a cat clone [bat][bat] written in Rust.
You need to generate SBOM from lock files like `Cargo.lock` at first.
```bash
$ git clone -b v0.20.0 https://github.com/sharkdp/bat
$ trivy fs --format cyclonedx --output bat.cdx ./bat/Cargo.lock
```
Then [our attestation plugin][plugin-attest] allows you to store the SBOM attestation linking to a `bat` binary in the Rekor instance.
```bash
$ wget https://github.com/sharkdp/bat/releases/download/v0.20.0/bat-v0.20.0-x86_64-apple-darwin.tar.gz
$ tar xvf bat-v0.20.0-x86_64-apple-darwin.tar.gz
$ trivy plugin install github.com/aquasecurity/trivy-plugin-attest
$ trivy attest --predicate ./bat.cdx --type cyclonedx ./bat-v0.20.0-x86_64-apple-darwin/bat
```
### Scan a non-packaged binary
Trivy calculates the digest of the `bat` binary and searches for the SBOM attestation by the digest in Rekor.

# SBOM attestation
[Cosign](https://github.com/sigstore/cosign) supports generating and verifying [in-toto attestations](https://github.com/in-toto/attestation). This tool enables you to sign and verify SBOM attestation.
And, Trivy can take an SBOM attestation as input and scan for vulnerabilities
!!! note
In the following examples, the `cosign` command will write an attestation to a target OCI registry, so you must have permission to write.
If you want to avoid writing an OCI registry and only want to see an attestation, add the `--no-upload` option to the `cosign` command.
## Sign with a local key pair
Cosign can generate key pairs and use them for signing and verification. After you run the following command, you will get a public and private key pair. Read more about [how to generate key pairs](https://docs.sigstore.dev/cosign/key-generation).
```bash
$ cosign generate-key-pair
```
In the following example, Trivy generates an SBOM in the CycloneDX format, and then Cosign attaches an attestation of the SBOM to a container image with a local key pair.
```bash
# The cyclonedx type is supported in Cosign v1.10.0 or later.
$ trivy image --format cyclonedx -o sbom.cdx.json <IMAGE>
$ cosign attest --key /path/to/cosign.key --type cyclonedx --predicate sbom.cdx.json <IMAGE>
```
Then, you can verify attestations on the image.
```bash
$ cosign verify-attestation --key /path/to/cosign.pub --type cyclonedx <IMAGE>
```
You can also create attestations of other formatted SBOM.
```bash
# spdx
$ trivy image --format spdx -o sbom.spdx <IMAGE>
$ cosign attest --key /path/to/cosign.key --type spdx --predicate sbom.spdx <IMAGE>
# spdx-json
$ trivy image --format spdx-json -o sbom.spdx.json <IMAGE>
$ cosign attest --key /path/to/cosign.key --type spdx --predicate sbom.spdx.json <IMAGE>
```
## Keyless signing
You can use Cosign to sign without keys by authenticating with an OpenID Connect protocol supported by sigstore (Google, GitHub, or Microsoft).
```bash
# The cyclonedx type is supported in Cosign v1.10.0 or later.
$ trivy image --format cyclonedx -o sbom.cdx.json <IMAGE>
# The following command uploads SBOM attestation to the public Rekor instance.
$ COSIGN_EXPERIMENTAL=1 cosign attest --type cyclonedx --predicate sbom.cdx.json <IMAGE>
```
You can verify attestations.
```bash
$ COSIGN_EXPERIMENTAL=1 cosign verify-attestation --type cyclonedx <IMAGE>
```
## Scanning
Trivy can take an SBOM attestation as input and scan for vulnerabilities. Currently, Trivy supports CycloneDX-type attestation.
In the following example, Cosign can get an CycloneDX-type attestation and trivy scan it.
You must create CycloneDX-type attestation before trying the example.
To learn more about how to create an CycloneDX-Type attestation and attach it to an image, see the [Sign with a local key pair](#sign-with-a-local-key-pair) section.
```bash
$ cosign verify-attestation --key /path/to/cosign.pub --type cyclonedx <IMAGE> > sbom.cdx.intoto.jsonl
$ trivy sbom ./sbom.cdx.intoto.jsonl

## Create Cosign Vulnerability Attestation
[Cosign](https://github.com/sigstore/cosign) supports generating and verifying [in-toto attestations](https://github.com/in-toto/attestation). This tool enables you to sign and verify Cosign vulnerability attestation.
!!! note
In the following examples, the `cosign` command will write an attestation to a target OCI registry, so you must have permission to write.
If you want to avoid writing an OCI registry and only want to see an attestation, add the `--no-upload` option to the `cosign` command.
### Sign with a local key pair
Cosign can generate key pairs and use them for signing and verification. After you run the following command, you will get a public and private key pair. Read more about [how to generate key pairs](https://docs.sigstore.dev/cosign/key-generation).
```bash
$ cosign generate-key-pair
```
In the following example, Trivy generates a cosign vulnerability scan record, and then Cosign attaches an attestation of it to a container image with a local key pair.
```
$ trivy image --format cosign-vuln --output vuln.json <IMAGE>
$ cosign attest --key /path/to/cosign.key --type vuln --predicate vuln.json <IMAGE>
```
Then, you can verify attestations on the image.
```
$ cosign verify-attestation --key /path/to/cosign.pub --type vuln <IMAGE>
```
### Keyless signing
You can use Cosign to sign without keys by authenticating with an OpenID Connect protocol supported by sigstore (Google, GitHub, or Microsoft).
```
$ trivy image --format cosign-vuln -o vuln.json <IMAGE>
$ COSIGN_EXPERIMENTAL=1 cosign attest --type vuln --predicate vuln.json <IMAGE>

# Amazon Web Services
!!! warning "EXPERIMENTAL"
This feature might change without preserving backwards compatibility.
The Trivy AWS CLI allows you to scan your AWS account for misconfigurations. You can either run the CLI locally or integrate it into your CI/CD pipeline.
Whilst you can already scan the infrastructure-as-code that defines your AWS resources with `trivy config`, you can now scan your live AWS account(s) directly too.
The included checks cover all of the aspects of the [AWS CIS 1.2](https://docs.aws.amazon.com/securityhub/latest/userguide/securityhub-standards-cis.html) automated benchmarks.
Trivy uses the same [authentication methods](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html) as the AWS CLI to configure and authenticate your access to the AWS platform.
You will need permissions configured to read all AWS resources - we recommend using a group/role with the `ReadOnlyAccess` policy attached.
Once you've scanned your account, you can run additional commands to filter the results without having to run the entire scan again - infrastructure information is cached locally per AWS account/region.
## CLI Commands
Scan a full AWS account (all supported services):
```shell
trivy aws --region us-east-1
```
You can allow Trivy to determine the AWS region etc. by using the standard AWS configuration files and environment variables. The `--region` flag overrides these.
![AWS Summary Report](../../../imgs/trivy-aws.png)
The summary view is the default when scanning multiple services.
Scan a specific service:
```shell
trivy aws --service s3
```
Scan multiple services:
```shell
# --service s3,ec2 works too
trivy aws --service s3 --service ec2
```
Show results for a specific AWS resource:
```shell
trivy aws --service s3 --arn arn:aws:s3:::example-bucket
```
All ARNs with detected issues will be displayed when showing results for their associated service.
## Cached Results
By default, Trivy will cache a representation of each AWS service for 24 hours. This means you can filter and view results for a service without having to wait for the entire scan to run again. If you want to force the cache to be refreshed with the latest data, you can use `--update-cache`. Or if you'd like to use cached data for a different timeframe, you can specify `--max-cache-age` (e.g. `--max-cache-age 2h`.). Regardless of whether the cache is used or not, rules will be evaluated again with each run of `trivy aws`.
## Custom Policies
You can write custom policies for Trivy to evaluate against your AWS account. These policies are written in [Rego](https://www.openpolicyagent.org/docs/latest/policy-language/), the same language used by [Open Policy Agent](https://www.openpolicyagent.org/). See the [Custom Policies](../../misconfiguration/custom/index.md) page for more information.

- See [Quick Start][quickstart]
- Fast
- The first scan will finish within 10 seconds (depending on your network). Consequent scans will finish in single seconds.
- Unlike other scanners that take long to fetch vulnerability information (~10 minutes) on the first run, and encourage you to maintain a durable vulnerability database, Trivy is stateless and requires no maintenance or preparation.
- Easy installation
- `apt-get install`, `yum install` and `brew install` is possible (See [Installation][installation])
- **No pre-requisites** such as installation of DB, libraries, etc.
- High accuracy
- **Especially Alpine Linux and RHEL/CentOS**
- Other OSes are also high
- DevSecOps
- **Suitable for CI** such as Travis CI, CircleCI, Jenkins, GitLab CI, etc.
- See [CI Example][integrations]
- Support multiple formats
- container image
- A local image in Docker Engine which is running as a daemon
- A local image in [Podman][podman] (>=2.0) which is exposing a socket
- A remote image in Docker Registry such as Docker Hub, ECR, GCR and ACR
- A tar archive stored in the `docker save` / `podman save` formatted file
- An image directory compliant with [OCI Image Format][oci]
- local filesystem and rootfs
- remote git repository
- [SBOM][sbom] (Software Bill of Materials) support
- CycloneDX

# Woodpecker CI
This is a simple example configuration `.woodpecker/trivy.yml` that shows how you could get started:
```yml
pipeline:
securitycheck:
image: aquasec/trivy:latest
commands:
# use any trivy command, if exit code is 0 woodpecker marks it as passed, else it assumes it failed
- trivy fs --exit-code 1 --skip-dirs web/ --skip-dirs docs/ --severity MEDIUM,HIGH,CRITICAL .

***Note*** : The `compliance` column represent the calculation of all tests pass vs. fail for all resources per control check in percentage format.
Example: if I have two resources in cluster and one resource scan result show pass while the other one show fail for `1.0 Non-root Containers` then it compliance will show 50%
An additional report is supported to get all of the detail the output contains, use `--report all`
```
$ trivy k8s cluster --compliance=nsa --report all
```
Report also supported in json format examples :
```
$ trivy k8s cluster --compliance=nsa --report summary --format json

# Kubernetes
!!! warning "EXPERIMENTAL"
This feature might change without preserving backwards compatibility.
The Trivy K8s CLI allows you to scan your Kubernetes cluster for Vulnerabilities, Secrets and Misconfigurations. You can either run the CLI locally or integrate it into your CI/CD pipeline. The difference to the Trivy CLI is that the Trivy K8s CLI allows you to scan running workloads directly within your cluster.
If you are looking for continuous cluster audit scanning, have a look at the [Trivy K8s operator.](../operator/index.md)
Trivy uses your local kubectl configuration to access the API server to list artifacts.
## CLI Commands
Scan a full cluster and generate a simple summary report:
```
$ trivy k8s --report=summary cluster
```
![k8s Summary Report](../../../imgs/trivy-k8s.png)
The summary report is the default. To get all of the detail the output contains, use `--report all`.
Filter by severity:
```
$ trivy k8s --severity=CRITICAL --report=all cluster
```
Filter by security check (Vulnerabilities, Secrets or Misconfigurations):
```
$ trivy k8s --security-checks=secret --report=summary cluster
# or
$ trivy k8s --security-checks=config --report=summary cluster
```
Scan a specific namespace:
```
$ trivy k8s -n kube-system --report=summary all
```
Use a specific kubeconfig file:
```
$ trivy k8s --kubeconfig ~/.kube/config2 -n kube-system --report=summary all
```
Scan a specific resource and get all the output:
```
$ trivy k8s deployment appname
```
Scan all deploys, or deploys and configmaps:
```
$ trivy k8s --report=summary deployment
$ trivy k8s --report=summary deployment,configmaps
```
If you want to pass in flags before scanning specific workloads, you will have to do it before the resource name.
For example, scanning a deployment in the app namespace of your Kubernetes cluster for critical vulnerabilities would be done through the following command:
```
$ trivy k8s -n app --severity=CRITICAL deployment/appname
```
This is specific to all Trivy CLI commands.
The supported formats are `table`, which is the default, and `json`.
To get a JSON output on a full cluster scan:
```
$ trivy k8s --format json -o results.json cluster
```

## Infra checks
Trivy by default scans kubernetes infra components (apiserver, controller-manager, scheduler and etcd)
if they exist under the `kube-system` namespace. For example, if you run a full cluster scan, or scan all
components under `kube-system` with commands:
```
$ trivy k8s cluster --report summary # full cluster scan
$ trivy k8s all -n kube-system --report summary # scan all componetns under kube-system
```
A table will be printed about misconfigurations found on kubernetes core components:
```
Summary Report for minikube
┌─────────────┬──────────────────────────────────────┬─────────────────────────────┐
│ Namespace │ Resource │ Kubernetes Infra Assessment │
│ │ ├────┬────┬────┬─────┬────────┤
│ │ │ C │ H │ M │ L │ U │
├─────────────┼──────────────────────────────────────┼────┼────┼────┼─────┼────────┤
│ kube-system │ Pod/kube-apiserver-minikube │ │ │ 1 │ 10 │ │
│ kube-system │ Pod/kube-controller-manager-minikube │ │ │ │ 3 │ │

└─────────────┴──────────────────────────────────────┴────┴────┴────┴─────┴────────┘
Severities: C=CRITICAL H=HIGH M=MEDIUM L=LOW U=UNKNOWN
```
The infra checks are based on CIS Benchmarks recommendations for kubernetes.
If you want filter only for the infra checks, you can use the flag `--components` along with the `--security-checks=config`
```
$ trivy k8s cluster --report summary --components=infra --security-checks=config # scan only infra
```
Or, to filter for all other checks besides the infra checks, you can:
```
$ trivy k8s cluster --report summary --components=workload --security-checks=config # scan all components besides infra
```

# Trivy Operator
Trivy has a native [Kubernetes Operator][operator] which continuously scans your Kubernetes cluster for security issues, and generates security reports as Kubernetes [Custom Resources][crd]. It does it by watching Kubernetes for state changes and automatically triggering scans in response to changes, for example initiating a vulnerability scan when a new Pod is created.

# License Scanning
Trivy scans any container image for license files and offers an opinionated view on the risk associated with the license.
License are classified using the [Google License Classification][google-license-classification] -
- Forbidden
- Restricted
- Reciprocal
- Notice
- Permissive
- Unencumbered
- Unknown
!!! tip
Licenses that Trivy fails to recognize are classified as UNKNOWN.
As those licenses may be in violation, it is recommended to check those unknown licenses as well.
By default, Trivy scans licenses for packages installed by `apk`, `apt-get`, `dnf`, `npm`, `pip`, `gem`, etc.
To enable extended license scanning, you can use `--license-full`.
In addition to package licenses, Trivy scans source code files, Markdown documents, text files and `LICENSE` documents to identify license usage within the image or filesystem.
!!! note
The full license scanning is expensive. It takes a while.
Currently, the standard license scanning doesn't support filesystem and repository scanning.
| License scnanning | Image | Rootfs | Filesystem | Repository |
|:---------------------:|:-----:|:---------:|:----------:|:----------:|
| Standard | ✅ | ✅ | - | - |
| Full (--license-full) | ✅ | ✅ | ✅ | ✅ |
License checking classifies the identified licenses and map the classification to severity.
| Classification | Severity |
|----------------|----------|
| Forbidden | CRITICAL |
| Restricted | HIGH |
| Reciprocal | MEDIUM |
| Notice | LOW |
| Permissive | LOW |
| Unencumbered | LOW |

## Configuration
Trivy has number of configuration flags for use with license scanning;
### Ignored Licenses
Trivy license scanning can ignore licenses that are identified to explicitly remove them from the results using the `--ignored-licenses` flag;
```shell
$ trivy image --security-checks license --ignored-licenses MPL-2.0,MIT --severity LOW grafana/grafana:latest
2022-07-13T18:15:28.605Z INFO License scanning is enabled
OS Packages (license)
=====================
Total: 2 (HIGH: 2, CRITICAL: 0)
┌───────────────────┬─────────┬────────────────┬──────────┐
│ Package │ License │ Classification │ Severity │
├───────────────────┼─────────┼────────────────┼──────────┤
│ alpine-baselayout │ GPL-2.0 │ Restricted │ HIGH │
├───────────────────┤ │ │ │
│ ssl_client │ │ │ │
└───────────────────┴─────────┴────────────────┴──────────┘
```
### Custom Classification
You can generate the default config by the `--generate-default-config` flag and customize the license classification.
For example, if you want to forbid only AGPL-3.0, you can leave it under `forbidden` and move other licenses to another classification.
```shell
$ trivy image --generate-default-config
$ vim trivy.yaml

People who want to scan a wide range of configuration files should use Trivy.

# Combined input
## Overview
Trivy usually scans each configuration file individually.
Sometimes it might be useful to compare values from different configuration files simultaneously.
When `combine` is set to true, all config files under the specified directory are combined into one input data structure.
!!! example
```
__rego_input__ := {
"combine": false,
}
```
In "combine" mode, the `input` document becomes an array, where each element is an object with two fields:
- `"path": "path/to/file"`: the relative file path of the respective file
- `"contents": ...`: the parsed content of the respective file
Now you can ensure that duplicate values match across the entirety of your configuration files.
## Return value
In "combine" mode, the `deny` entrypoint must return an object with two keys
`filepath` (required)
: the relative file path of the file being evaluated
`msg` (required)
: the message describing an issue
!!! example
```
deny[res] {
resource := input[i].contents
... some logic ...
res := {
"filepath": input[i].path,
"msg": "something bad",
}
}
```

# Custom Data
Custom policies may require additional data in order to determine an answer.
For example, an allowed list of resources that can be created.
Instead of hardcoding this information inside of your policy, Trivy allows passing paths to data files with the `--data` flag.
Given the following yaml file:
```bash
$ cd examples/misconf/custom-data
$ cat data/ports.yaml [~/src/github.com/aquasecurity/trivy/examples/misconf/custom-data]
services:
ports:
- "20"
- "20/tcp"
- "20/udp"
- "23"
- "23/tcp"
```
This can be imported into your policy:
```rego
import data.services
ports := services.ports
```
Then, you need to pass data paths through `--data` option.
Trivy recursively searches the specified paths for JSON (`*.json`) and YAML (`*.yaml`) files.
```bash
$ trivy conf --policy ./policy --data data --namespaces user ./configs
```

# Debugging policies
When working on more complex queries (or when learning Rego), it's useful to see exactly how the policy is applied.
For this purpose you can use the `--trace` flag.
This will output a large trace from Open Policy Agent like the following:
!!! tip
Only failed policies show traces. If you want to debug a passed policy, you need to make it fail on purpose.
```shell
$ trivy conf --trace configs/

═══════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════
Running containers with 'root' user can lead to a container escape situation. It is a best practice to run containers as non-root users, which can be done by adding a 'USER' statement to the Dockerfile.

# Examples
## Custom Policy
### Kubernetes
See [here][k8s].
The custom policy is defined in `user.kubernetes.ID001` package.
You need to pass the package prefix you want to evaluate through `--namespaces` option.
In this case, the package prefix should be `user`, `user.kubernetes`, or `user.kubernetes.ID001`.
### Dockerfile
See [here][dockerfile].
The input will be a dictionary of stages.
#### Single Stage
??? example
Dockerfile
```dockerfile
FROM foo
COPY . /
RUN echo hello
```
Rego Input
```json

# Custom Policies
## Overview
You can write custom policies in [Rego][rego].
Once you finish writing custom policies, you can pass the directory where those policies are stored with `--policy` option.
``` bash
trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
```
As for `--namespaces` option, the detail is described as below.
### File formats
If a file name matches the following file patterns, Trivy will parse the file and pass it as input to your Rego policy.
| File format | File pattern |
|---------------|-----------------------------------------------------------|
| JSON | `*.json` |
| YAML | `*.yaml` and `*.yml` |
| Dockerfile | `Dockerfile`, `Dockerfile.*`, and `*.Dockerfile` |
| Containerfile | `Containerfile`, `Containerfile.*`, and `*.Containerfile` |
| Terraform | `*.tf` and `*.tf.json` |
### Configuration languages
In the above general file formats, Trivy automatically identifies the following types of configuration files:
- CloudFormation (JSON/YAML)
- Kubernetes (JSON/YAML)
- Helm (YAML)
- Terraform Plan (JSON)
This is useful for filtering inputs, as described below.
## Rego format
A single package must contain only one policy.
!!!example
``` rego
# METADATA
# title: Deployment not allowed
# description: Deployments are not allowed because of some reasons.
# schemas:
# - input: schema.input
# custom:
# id: ID001
# severity: LOW
# input:
# selector:
# - type: kubernetes
package user.kubernetes.ID001
deny[res] {
input.kind == "Deployment"
msg := sprintf("Found deployment '%s' but deployments are not allowed", [input.metadata.name])
res := result.new(msg, input.kind)
}
```
In this example, ID001 "Deployment not allowed" is defined under `user.kubernetes.ID001`.
If you add a new custom policy, it must be defined under a new package like `user.kubernetes.ID002`.
### Policy structure
`# METADATA` (optional)
: - SHOULD be defined for clarity since these values will be displayed in the scan results
- `custom.input` SHOULD be set to indicate the input type the policy should be applied to. See [list of available types](https://github.com/aquasecurity/defsec/blob/418759b4dc97af25f30f32e0bd365be7984003a1/pkg/types/sources.go)
`package` (required)
: - MUST follow the Rego's [specification][package]
- MUST be unique per policy
- SHOULD include policy id for uniqueness
- MAY include the group name such as `kubernetes` for clarity
- Group name has no effect on policy evaluation
`deny` (required)
: - SHOULD be `deny` or start with `deny_`
- Although `warn`, `warn_*`, `violation`, `violation_` also work for compatibility, `deny` is recommended as severity can be defined in `__rego_metadata__`.
- SHOULD return ONE OF:
- The result of a call to `result.new(msg, cause)`. The `msg` is a `string` describing the issue occurrence, and the `cause` is the property/object where the issue occurred. Providing this allows Trivy to ascertain line numbers and highlight code in the output.
- A `string` denoting the detected issue
- Although `object` with `msg` field is accepted, other fields are dropped and `string` is recommended if `result.new()` is not utilised.
- e.g. `{"msg": "deny message", "details": "something"}`
### Package
A package name must be unique per policy.
!!!example
``` rego
package user.kubernetes.ID001
```
By default, only `builtin.*` packages will be evaluated.
If you define custom packages, you have to specify the package prefix via `--namespaces` option.
``` bash
trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
```
In this case, `user.*` will be evaluated.
Any package prefixes such as `main` and `user` are allowed.
### Metadata
Metadata helps enrich Trivy's scan results with useful information.
The annotation format is described in the [OPA documentation](https://www.openpolicyagent.org/docs/latest/annotations/).
Trivy supports extra fields in the `custom` section as described below.
!!!example
``` rego
# METADATA
# title: Deployment not allowed
# description: Deployments are not allowed because of some reasons.
# custom:
# id: ID001
# severity: LOW
# input:
# selector:
# - type: kubernetes
```
All fields are optional. The `schemas` field should be used to enable policy validation using a built-in schema. The
schema that will be used is based on the input document type. It is recommended to use this to ensure your policies are
correct and do not reference incorrect properties/values.
| Field name | Allowed values | Default value | In table | In JSON |
|----------------------------|------------------------------------------|:----------------------------:|:----------------:|:----------------:|
| title | Any characters | N/A | :material-check: | :material-check: |
| description | Any characters | | :material-close: | :material-check: |
| schemas.input | `schema.input` | (applied to all input types) | :material-close: | :material-close: |
| custom.id | Any characters | N/A | :material-check: | :material-check: |
| custom.severity | `LOW`, `MEDIUM`, `HIGH`, `CRITICAL` | UNKNOWN | :material-check: | :material-check: |
| custom.recommended_actions | Any characters | | :material-close: | :material-check: |
| custom.input.selector.type | Any item(s) in [this list][source-types] | | :material-close: | :material-check: |
| url | Any characters | | :material-close: | :material-check: |
Some fields are displayed in scan results.
``` bash
k.yaml (kubernetes)
───────────────────
Tests: 32 (SUCCESSES: 31, FAILURES: 1, EXCEPTIONS: 0)
Failures: 1 (UNKNOWN: 0, LOW: 1, MEDIUM: 0, HIGH: 0, CRITICAL: 0)
LOW: Found deployment 'my-deployment' but deployments are not allowed
════════════════════════════════════════════════════════════════════════
Deployments are not allowed because of some reasons.
────────────────────────────────────────────────────────────────────────
k.yaml:1-2
────────────────────────────────────────────────────────────────────────
1 ┌ apiVersion: v1
2 └ kind: Deployment
────────────────────────────────────────────────────────────────────────
```
### Input
You can specify input format via the `custom.input` annotation.
!!!example
``` rego
# METADATA
# custom:
# input:
# combine: false
# selector:
# - type: kubernetes
```
`combine` (boolean)
: The details are [here](combine.md).
`selector` (array)
: This option filters the input by file format or configuration language.
In the above example, Trivy passes only Kubernetes files to this policy.
Even if a Dockerfile exists in the specified directory, it will not be passed to the policy as input.
Possible values for input types are:
- `dockerfile` (Dockerfile)
- `kubernetes` (Kubernetes YAML/JSON)
- `rbac` (Kubernetes RBAC YAML/JSON)
- `cloud` (Cloud format, as defined by defsec - this is used for Terraform, CloudFormation, and Cloud/AWS scanning)
- `yaml` (Generic YAML)
- `json` (Generic JSON)
- `toml` (Generic TOML)
When configuration languages such as Kubernetes are not identified, file formats such as JSON will be used as `type`.
When a configuration language is identified, it will overwrite `type`.
!!! example
`pod.yaml` including Kubernetes Pod will be handled as `kubernetes`, not `yaml`.
`type` is overwritten by `kubernetes` from `yaml`.
`type` accepts `kubernetes`, `dockerfile`, `cloudformation`, `terraform`, `terraformplan`, `json`, or `yaml`.
### Schemas
You can explore the format of input documents by browsing the schema for the relevant input type:
- [Cloud](https://github.com/aquasecurity/defsec/blob/master/pkg/rego/schemas/cloud.json)
- [Dockerfile](https://github.com/aquasecurity/defsec/blob/master/pkg/rego/schemas/dockerfile.json)
- [Kubernetes](https://github.com/aquasecurity/defsec/blob/master/pkg/rego/schemas/kubernetes.json)
- [RBAC](https://github.com/aquasecurity/defsec/blob/master/pkg/rego/schemas/rbac.json)

# Testing
It is highly recommended to write tests for your custom policies.
## Rego testing
To help you verify the correctness of your custom policies, OPA gives you a framework that you can use to write tests for your policies.
By writing tests for your custom policies you can speed up the development process of new rules and reduce the amount of time it takes to modify rules as requirements evolve.
For more details, see [Policy Testing][opa-testing].
!!! example
```
package user.dockerfile.ID002
test_add_denied {
r := deny with input as {"stages": {"alpine:3.13": [
{"Cmd": "add", "Value": ["/target/resources.tar.gz", "resources.jar"]},
{"Cmd": "add", "Value": ["/target/app.jar", "app.jar"]},
]}}
count(r) == 1
r[_] == "Consider using 'COPY /target/app.jar app.jar' command instead of 'ADD /target/app.jar app.jar'"
}
```
To write tests for custom policies, you can refer to existing tests under [defsec][defsec].
## Go testing
[Fanal][fanal] which is a core library of Trivy can be imported as a Go library.
You can scan config files in Go and test your custom policies using Go's testing methods, such as [table-driven tests][table].
This allows you to use the actual configuration file as input, making it easy to prepare test data and ensure that your custom policies work in practice.
In particular, Dockerfile and HCL need to be converted to structural data as input, which may be different from the expected input format.
!!! tip
We recommend writing OPA and Go tests both since they have different roles, like unit tests and integration tests.
The following example stores allowed and denied configuration files in a directory.
`Successes` contains the result of successes, and `Failures` contains the result of failures.
``` go
{
name: "disallowed ports",
input: "configs/",
fields: fields{
policyPaths: []string{"policy"},
dataPaths: []string{"data"},
namespaces: []string{"user"},
},
want: []types.Misconfiguration{
{
FileType: types.Dockerfile,
FilePath: "Dockerfile.allowed",
Successes: types.MisconfResults{
{
Namespace: "user.dockerfile.ID002",
PolicyMetadata: types.PolicyMetadata{
ID: "ID002",
Type: "Docker Custom Check",
Title: "Disallowed ports exposed",
Severity: "HIGH",
},
},
},
},
{
FileType: types.Dockerfile,
FilePath: "Dockerfile.denied",
Failures: types.MisconfResults{
{
Namespace: "user.dockerfile.ID002",
Message: "Port 23 should not be exposed",
PolicyMetadata: types.PolicyMetadata{
ID: "ID002",
Type: "Docker Custom Check",
Title: "Disallowed ports exposed",
Severity: "HIGH",
},
},
},
},
},
},
```
`Dockerfile.allowed` has one successful result in `Successes`, while `Dockerfile.denied` has one failure result in `Failures`.

# Policy
## Pass custom policies
You can pass directories including your custom policies through `--policy` option.
This can be repeated for specifying multiple directories.
```bash
cd examplex/misconf/
trivy conf --policy custom-policy/policy --policy combine/policy --namespaces user misconf/mixed
```
For more details, see [Custom Policies](../custom/index.md).
!!! tip
You also need to specify `--namespaces` option.
## Pass custom data
You can pass directories including your custom data through `--data` option.
This can be repeated for specifying multiple directories.
```bash
cd examples/misconf/custom-data
trivy conf --policy ./policy --data ./data --namespaces user ./configs
```
For more details, see [Custom Data](../custom/data.md).
## Pass namespaces
By default, Trivy evaluates policies defined in `builtin.*`.
If you want to evaluate custom policies in other packages, you have to specify package prefixes through `--namespaces` option.
This can be repeated for specifying multiple packages.
``` bash
trivy conf --policy ./policy --namespaces main --namespaces user ./configs

# Value Overrides
Value files can be passed for supported scannable config files.
## Terraform value overrides
You can pass `tf-vars` files to Trivy to override default values found in the Terraform HCL code.
```bash
trivy conf --tf-vars dev.terraform.tfvars ./infrastructure/tf
```
## Helm value overrides
There are a number of options for overriding values in Helm charts. When override values are passed to the Helm scanner, the values will be used during the Manifest rendering process and will become part of the scanned artifact.
### Setting inline value overrides
Overrides can be set inline on the command line
```bash
trivy conf --helm-set securityContext.runAsUser=0 ./charts/mySql
```
### Setting value file overrides
Overrides can be in a file that has the key=value set.
```yaml
# Example override file (overrides.yaml)
securityContext:
runAsUser: 0
```
```bash
trivy conf --helm-values overrides.yaml ./charts/mySql

### Setting value as explicit string
the `--helm-set-string` is the same as `--helm-set` but explicitly retains the value as a string
```bash
trivy config --helm-set-string name=false ./infrastructure/tf

# Built-in Policies
## Policy Sources
Built-in policies are mainly written in [Rego][rego] and Go.
Those policies are managed under [defsec repository][defsec].
| Config type | Source |
|---------------------------|----------------------|
| Kubernetes | [defsec][kubernetes] |
| Dockerfile, Containerfile | [defsec][docker] |
| Terraform | [defsec][defsec] |
| CloudFormation | [defsec][defsec] |
| Azure ARM Template | [defsec][defsec] |
| Helm Chart | [defsec][kubernetes] |
| RBAC | [defsec][rbac] |
For suggestions or issues regarding policy content, please open an issue under the [defsec][defsec] repository.
Helm Chart scanning will resolve the chart to Kubernetes manifests then run the [kubernetes][kubernetes] checks.
Ansible scanning is coming soon.

# Exceptions
Exceptions let you specify cases where you allow policy violations.
Trivy supports two types of exceptions.
!!! info
Exceptions can be applied to built-in policies as well as custom policies.
## Namespace-based exceptions
There are some cases where you need to disable built-in policies partially or fully.
Namespace-based exceptions lets you rough choose which individual packages to exempt.
To use namespace-based exceptions, create a Rego rule with the name `exception` that returns the package names to exempt.
The `exception` rule must be defined under `namespace.exceptions`.
`data.namespaces` includes all package names.
!!! example
``` rego
package namespace.exceptions
import data.namespaces
exception[ns] {
ns := data.namespaces[_]
startswith(ns, "builtin.kubernetes")
}
```
This example exempts all built-in policies for Kubernetes.
For more details, see [an example][ns-example].
## Rule-based exceptions
There are some cases where you need more flexibility and granularity in defining which cases to exempt.
Rule-based exceptions lets you granularly choose which individual rules to exempt, while also declaring under which conditions to exempt them.
To use rule-based exceptions, create a Rego rule with the name `exception` that returns the rule name suffixes to exempt, prefixed by `deny_` (for example, returning `foo` will exempt `deny_foo`).
The rule can make any other assertion, for example, on the input or data documents.
This is useful to specify the exemption for a specific case.
Note that if you specify the empty string, the exception will match all rules named `deny`.
```
exception[rules] {
# Logic
rules = ["foo","bar"]
}
```
The above would provide an exception from `deny_foo` and `deny_bar`.
!!! example
```
package user.kubernetes.ID100
__rego_metadata := {
"id": "ID100",
"title": "Deployment not allowed",
"severity": "HIGH",
"type": "Kubernetes Custom Check",
}
deny_deployment[msg] {
input.kind == "Deployment"
msg = sprintf("Found deployment '%s' but deployments are not allowed", [name])
}
exception[rules] {
input.kind == "Deployment"
input.metadata.name == "allow-deployment"
rules := ["deployment"]
}
```
If you want to apply rule-based exceptions to built-in policies, you have to define the exception under the same package.
!!! example
``` rego
package builtin.kubernetes.KSV012
exception[rules] {
input.metadata.name == "can-run-as-root"
rules := [""]
}
```
This exception is applied to [KSV012][ksv012] in defsec.
You can get the package names in the [defsec repository][defsec] or the JSON output from Trivy.
For more details, see [an example][rule-example].
