CCSP Cloud Security Operations Practice Question
A cloud security team wants to automatically remediate misconfigured S3 buckets that are publicly accessible. Which combination of AWS services can be used to detect and automatically fix this issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Config and AWS Lambda
AWS Config evaluates resource configurations against rules (e.g., 's3-bucket-public-read-prohibited'). When a non-compliant resource is detected, AWS Config can trigger a Lambda function via a custom remediation action to modify the bucket policy. GuardDuty detects threats but does not remediate. Security Hub aggregates findings but does not automatically fix issues. CloudTrail logs events but does not evaluate configurations.
