ISC Security Planning And Engineering Practice Question
An ISSEP is conducting a gap analysis between a legacy system and ISO/IEC 27001 requirements. The system lacks automated audit logging. Which control implementation is most effective for meeting the 'Logging and Monitoring' requirements?
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
✓
Implement centralized log aggregation using a SIEM solution with automated alerting.
Centralized log management (like a SIEM) allows for aggregation, alerting, and forensic analysis, which is fundamental to ISO 27001 compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement centralized log aggregation using a SIEM solution with automated alerting.
Why this is correct
This satisfies the requirement for monitoring and auditability in ISO 27001.
- ✗
Redirect all logs to a local write-only file system on each server.
Why it's wrong here
Local logs are vulnerable to tampering and do not support centralized analysis.
- ✗
Disable unnecessary services to reduce the attack surface.
Why it's wrong here
Hardening is a valid security practice, but it does not satisfy the requirement for audit logging.
- ✗
Require manual review of system event logs by administrators weekly.
Why it's wrong here
Manual processes are prone to error and do not meet the timeliness requirements for monitoring.
