CIS Controls 13.1: Centralize Security Event Alerting
Security events scattered across your infrastructure create blind spots. CIS Controls 13.1 requires centralized event alerting through a SIEM or log analytics platform to detect threats before they escalate. This control is critical for detecting and responding to compromise in real time.
What this means
Centralized security event alerting consolidates logs and security events from all enterprise assets into a single platform for correlation and analysis. This includes implementing a SIEM (Security Information and Event Management) system or equivalent log analytics platform configured with vendor-defined or custom correlation rules. The goal is to identify patterns, anomalies, and potential threats that would be invisible in isolated logs.
How to comply
- 1.Deploy a SIEM platform or log analytics solution that aggregates logs from all critical enterprise assets
- 2.Configure vendor-defined event correlation alerts to automatically detect suspicious patterns
- 3.Establish logging standards to ensure consistent event formatting across sources
- 4.Define alert thresholds and response procedures for high-priority security events
- 5.Test correlation rules regularly to validate detection effectiveness
- 6.Document all configured alerts and their business justification
- 7.Monitor alert fatigue and tune rules to reduce false positives
Evidence auditors look for
- SIEM deployment documentation showing all monitored assets and data sources
- List of active correlation rules with alert definitions and severity levels
- Alert testing results demonstrating detection of known attack patterns
- Incident response logs showing alerts triggered and analyst actions taken
- Configuration reports from your SIEM showing event retention and log sources
- Dashboard screenshots showing real-time event correlation and trending
- Alert tuning logs documenting false positive reduction and rule optimization
