## EFS

### `elasticfilesystem:DeleteMountTarget`
An attacker could delete a mount target, potentially disrupting access to the EFS file system for applications and users relying on that mount target.
```sql
aws efs delete-mount-target --mount-target-id
```
**Potential Impact**: Disruption of file system access and potential data loss for users or applications.
### `elasticfilesystem:DeleteFileSystem`
An attacker could delete an entire EFS file system, which could lead to data loss and impact applications relying on the file system.
```perl
aws efs delete-file-system --file-system-id
```
**Potential Impact**: Data loss and service disruption for applications using the deleted file system.
### `elasticfilesystem:UpdateFileSystem`
An attacker could update the EFS file system properties, such as throughput mode, to impact its performance or cause resource exhaustion.
```sql
aws efs update-file-system --file-system-id --provisioned-throughput-in-mibps
```
**Potential Impact**: Degradation of file system performance or resource exhaustion.
### `elasticfilesystem:CreateAccessPoint` and `elasticfilesystem:DeleteAccessPoint`
An attacker could create or delete access points, altering access control and potentially granting themselves unauthorized access to the file system.
```arduino
aws efs create-access-point --file-system-id --posix-user --root-directory
aws efs delete-access-point --access-point-id
```
**Potential Impact**: Unauthorized access to the file system, data exposure or modification.
