17.9 Establish and Maintain Security Incident Thresholds
Set and maintain thresholds for security incidents, at minimum distinguishing an incident from an event, with examples such as abnormal activity, security vulnerabilities and weaknesses, data breaches and privacy incidents. Review yearly or after significant change. Implementation Group: IG3 only (for enterprises facing sophisticated attackers or holding highly sensitive data). Asset type: Documentation. Security function: Recover.

Each safeguard shows its Implementation Groups. IG1 is the essential baseline for every enterprise, IG2 adds to it, IG3 is all 153. Version 8.1 adds the Govern security function and asks for more processes to be documented; numbering is unchanged from v8.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
