PIMS-specific requirements related to ISO/IEC 27001, ISO 27701:2019
ISO 27701:2019 5.8.2: Continual improvement
The continual improvement requirement of ISO/IEC 27001 applies to the PIMS, so the organization must keep improving the suitability, adequacy and effectiveness of the privacy extension and not only correct it when it fails.
This control maps to 61 controls across 39 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-ID.IM-02 Improvements are identified from security tests and exercises, including those done in coordination with suppliers and relevant third parties
NIST-CSF-ID.IM-03 Improvements are identified from execution of operational processes, procedures, and activities
You are reading one control. How much of ISO 27701:2019 have you already done?
ISO 27701:2019 5.8.2 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27701:2019 your existing evidence covers. Hold SOC 2 and 58 of 108 ISO 27701:2019 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. 289 were rejected on the SOC 2 pair alone.
