description: |
|
|
Checks if Amazon Machine Images (AMIs) are publicly shared, potentially exposing sensitive data.
|
|
impact: |
|
|
Public sharing of AMIs can lead to unauthorized access and compromise of sensitive information contained within these images.
|
|
remediation: |
|
|
Restrict AMI sharing to specific, trusted AWS accounts and ensure they are not publicly accessible.
