ISC2 CC Practice Question: Wants to ensure that critical security events are…
An organization wants to ensure that critical security events are not missed during off-hours. What is the best practice?
⚠ Common exam trap
ISC2 often tests the distinction between proactive security measures (like scheduled scans) and reactive monitoring practices (like 24/7 SIEM analysis), leading candidates to confuse vulnerability management with real-time event detection.

Correct answer & explanation
✓
Configure a central SIEM with 24/7 monitoring
A central SIEM with 24/7 monitoring ensures that security events are continuously analyzed and alerted upon, even during off-hours. This is the best practice because it provides real-time correlation and escalation of critical events, preventing them from being missed. Relying on automatic responses or periodic scans lacks the human oversight needed for complex threat validation.

Rely on automatic responses
Why it's wrong here
Automatic responses may not handle all scenarios and can miss subtle indicators.

Schedule nightly scans
Why it's wrong here
Scans are not real-time; events outside scans are missed.
