AWS S3 Lifecycle Policy

Overview​

It is critical to attach a lifecycle policy to all S3 buckets to properly manage data retention and minimize costs. This policy checks whether a lifecycle policy is applied to each S3 bucket and alerts if it is missing.

Pros and Cons​

Pros​

  • Cost Management: Automates data deletion or transition to cheaper storage classes, reducing costs.
  • Data Compliance: Easy management of data retention policies.

Cons​

  • False Positives: Buckets that intentionally do not have lifecycle policies for valid reasons may still be flagged.

How the Policy Works​

The policy uses AWS SDK to check each S3 bucket's lifecycle policy. If no lifecycle policy is found, a violation is reported.

Variables​

  • No variables are required for this policy.

Violation Types​

  • LIFECYCLE_POLICY_MISSING: Indicates that the S3 bucket does not have a lifecycle policy.
