Ensure Images (AMI) are not older than 90 days
Description
Ensure that your AMIs are not older than 90 days.
Rationale
Using up-to-date AMIs will provide many benefits from OS updates and security patches helping to ensure reliability, security and compliance.
Impact
Outdated AMIs must be replaced by creating new images from updated instances. This requires a refresh cycle that involves launching instances, applying updates, creating new AMIs, and deregistering old ones.
Audit Procedure
Using AWS CLI
Run the aws ec2 describe-images command:
aws ec2 describe-images \
--region <region> \
--image-ids <image-ID>
