AWS S3 Security Posture
AWS S3 Security Overview
S3 buckets deployed for static website hosting are frequently misconfigured with overly permissive public access ACLs. Best practice dictates blocking public access and routing traffic through CloudFront.
Security Checks
Public Access (warn)
Buckets should have 'Block Public Access' enabled unless explicitly serving static website assets directly.
CloudFront Integration (pass)
Using Origin Access Control (OAC) with CloudFront secures the bucket from direct access.
Encryption (pass)
Server-side encryption is now applied by default to all new objects.
These technical checks are informational heuristics, not a guarantee of security or compliance. Passing a scan does not guarantee protection against zero-days or application logic flaws. Always conduct independent professional audits.
