Security Monitoring Gaps
Log Coverage Gaps
Critical detection signals are not being collected — attacks pass through invisible.
What it is
Windows security event logs (4624, 4648, 4688), DNS query logs, PowerShell script block logging, cloud audit trails, and endpoint process execution events are frequently not collected, not forwarded to the SIEM, or collected without enrichment. Without the raw log data, no detection rule can fire regardless of how well it is written. Log coverage mapping against the MITRE ATT&CK framework reveals which techniques are structurally invisible.
Attack techniques
- Missing Windows event log forwarding
- No DNS query logging
- PowerShell logging disabled
- Cloud audit trail gaps (CloudTrail, Azure Monitor)
- Endpoint telemetry not reaching SIEM
Business impact
Attackers operating in environments with log gaps can execute entire intrusion chains — credential theft, lateral movement, data staging — without generating a single alert.
