Additional ISO/IEC 27002 guidance for PII controllers, ISO 27701:2019
ISO 27701:2019 7.2.1: Identify and document purpose
The organization must establish, and record, the specific purposes that personal data will be processed for, documented clearly and in enough detail to be usable in the information given to individuals, in obtaining consent, and in the records of policies and procedures, so that individuals understand why their data is processed.
This control maps to 30 controls across 14 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 27701:2019 have you already done?
ISO 27701:2019 7.2.1 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.
