What it detects

This rule flags Okta events where a policy decision for sign-on is evaluated against the target “Okta Admin Console” and the event’s debug heuristics indicate a “POSITIVE” behavior. Attackers may use the Admin Console for privilege escalation or persistence, and these signals can help surface newly identified or atypical admin-console-related activity. Telemetry relies on Okta system log fields including eventType, target.displayName, and debugContext.debugData values containing the marker strings.
