Updating CRLs Privately with AWS Private CA and VPC Delivery

🔒 This AWS Security post explains two approaches to make certificate revocation lists (CRLs) available only to internal systems without exposing the S3 CRL bucket to the public internet. The first approach relocates CRLs by using a custom CDP CNAME and an EventBridge‑triggered Lambda that copies generated CRLs from the ACM Private CA S3 bucket to an internal store, with SNS notifications and example Python code. The second approach confines CRL retrieval inside AWS by using a VPC Gateway S3 endpoint, tightly scoped S3 bucket policies, and private Route 53 DNS so CRLs are resolvable and retrievable only from within the VPC.
