Using MITRE ATT&CK to find your detection gaps

5 November 2026 · 1 min read · Nigehban security team

MITRE ATT&CK catalogues how attackers behave, from initial access to exfiltration. Mapping each of your detection rules to the techniques it covers produces a coverage map, and the empty areas are your blind spots.

Prioritise by relevance, not completeness. Choose the techniques used against organisations like yours, then check that you have both the log data and the rule to detect them.

Validate by testing. A rule that has never fired may be perfect or broken, and only a controlled test, such as an authorised red team exercise, tells you which.
