AWS Certified Security – Specialty — Question 135
A company's AWS CloudTrail logs are all centrally stored in an Amazon S3 bucket. The security team controls the company's AWS account. The security team must prevent unauthorized access and tampering of the CloudTrail logs.
Which combination of steps should the security team take? (Choose three.)
Answer options
- A. Configure server-side encryption with AWS KMS managed encryption keys (SSE-KMS)
- B. Compress log file with secure gzip.
- C. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to notify the security team of any modifications on CloudTrail log files.
- D. Implement least privilege access to the S3 bucket by configuring a bucket policy.
- E. Configure CloudTrail log file integrity validation.
- F. Configure Access Analyzer for S3.
Correct answer: A, D, E
Explanation
The correct steps involve configuring server-side encryption with AWS KMS managed keys (A) to secure the logs, applying least privilege access through a bucket policy (D) to restrict access, and enabling log file integrity validation (E) to ensure the logs have not been tampered with. Options B and C, while useful, do not directly address the security requirements, and F does not prevent unauthorized access or tampering of the logs.
