False Positives and False Negatives

A false positive occurs when a security control reports malicious activity that is not actually present, while a false negative occurs when genuine malicious activity is missed. Certification exams may ask candidates to identify these outcomes or explain the tradeoff created when detection thresholds are adjusted. A rule that alerts on every administrative script may create excessive false positives, while a rule that requires several severe conditions may overlook a real attack. Defenders should tune controls using validated data, asset criticality, threat context, and acceptable risk rather than attempting to eliminate one error type completely. Testing, analyst feedback, rule reviews, and comparison with confirmed incidents help improve accuracy. False negatives may leave threats undetected, while excessive false positives can consume resources and contribute to alert fatigue.
