AWS S3 Bucket Policy Restricts Principal

Risk

Remediation Effort

High

Low

This policy validates that S3 Bucket access policies do not allow any principal for a given action on the bucket, in accordance with the principle of least privilege.

Remediation

To remediate this, modify any grants in the S3 Bucket access policy that have Effect:Allow on Princiapl:*. New, more restrictive grants may be needed in their place to maintain access.
