description: |
|
|
Identify and secure fully accessible Amazon VPC endpoints to prevent unauthorized access to AWS services.
|
|
impact: |
|
|
Allows unrestricted access to AWS services via the exposed VPC endpoint, potentially leading to data leakage or unauthorized operations.
|
|
remediation: |
|
|
Update the VPC endpoint's policy to restrict access only to authorized entities and ensure all requests are signed.
