This control maps to 43 controls across 26 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
You are reading one control. How much of ISO 22301:2019 have you already done?
ISO 22301:2019 7.5.1 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 22301:2019 your existing evidence covers. Hold APRA CPS 230 Operational Risk Management and 28 of 57 ISO 22301:2019 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 0 were rejected on the APRA CPS 230 Operational Risk Management pair alone.
