What it detects

This rule identifies when a Bitbucket global secret scanning rule is deleted via an audit event. Attackers may remove secret scanning controls to reduce the chance of detecting sensitive data exposure or configuration issues. The detection relies on Bitbucket audit log telemetry capturing the event category and action for global administration and rule deletion.
