Does your incident response process account for known false positives when determining incident classification and response criteria?

Explanation

Handling of known false positives is what this examines: whether your incident response process factors them in when classifying incidents and setting response criteria. False positives can consume valuable resources and create alert fatigue if not properly managed. Effective incident response processes should include criteria that help distinguish genuine security incidents from false alarms based on historical data and known system behaviors.

Evidence could include documentation of your incident classification framework that specifically addresses false positive handling, historical data showing false positive rates and adjustments made, or runbooks that include steps for validating alerts before escalation.
