CCSP Cloud Security Operations Practice Question
A cloud security team is designing an incident response playbook for a suspected data exfiltration via an AWS S3 bucket. Which TWO actions should be included for containment and evidence collection? (Choose two.)
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
✓
Revoke IAM credentials associated with the compromised access.
For containment, revoking the IAM credentials used by the attacker stops further access. For evidence, enabling VPC Flow Logs (if not already enabled) captures network traffic for analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Immediately notify all users to change passwords.
Why it's wrong here
Not a containment or evidence step for this specific incident.
- ✓
Revoke IAM credentials associated with the compromised access.
Why this is correct
Stops further API calls.
- ✗
Take a snapshot of the S3 bucket using AWS Backup.
Why it's wrong here
S3 is not a snapshot; versioning or bucket inventory might be used, but not snapshot.
- ✓
Enable VPC Flow Logs for the VPC where the bucket is accessed.
Why this is correct
Captures network flows for forensic analysis.
- ✗
Delete the S3 bucket to prevent further access.
Why it's wrong here
Deletion destroys evidence.
