CAS-004 Security Operations Practice Question
A security operations center (SOC) is implementing a SOAR platform to automate responses to phishing incidents. The playbook will include steps to automatically quarantine suspicious emails, delete them from user mailboxes, and block the sender's domain. Which element should the SOAR playbook incorporate to ensure the automated response does not cause unintended disruption?
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
✓
A confirmation step that prompts the analyst to approve the quarantine and deletion actions
Automated actions can have negative consequences if not validated. Incorporating user confirmation before destructive actions reduces risk, especially in cases of false positives.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An automatic rollback script that restores quarantined emails after 24 hours if no user complaint
Why it's wrong here
Automatic rollback could reintroduce malicious content and does not address the need for oversight.
- ✗
Integration with threat intelligence to verify the sender domain reputation score before blocking
Why it's wrong here
While threat intel helps, it may not prevent all false positives; the question asks about avoiding unintended disruption.
- ✓
A confirmation step that prompts the analyst to approve the quarantine and deletion actions
Why this is correct
Having the analyst approve destructive actions like deletion reduces the risk of removing legitimate emails.
- ✗
A manual approval step before executing any automated response
Why it's wrong here
Full manual approval defeats the purpose of automation; a better approach is conditional approval only for high-risk actions.
