Non-encrypted confidential information - S3 Server Side Encryption

Description

Some S3 buckets do not explicitly enable the Server-Side-Encryption (SSE) property. So the stored objects are not encrypted at rest, exposing their content to leaks by attackers or unauthorized users.

Impact

Compromise sensitive data stored in the bucket in plaintext.

Recommendation

Enable the SSE property in all S3 instances.

Threat

Authenticated attacker from Internet with access to the bucket.

Expected Remediation Time

⌚ 15 minutes.
