ISO 27001:2022 8.12: Data leakage prevention

Every system, network and other device that handles, holds or sends sensitive information is to be covered by measures that stop data leaking. Purpose (stated in ISO/IEC 27002:2022): spots and stops information being disclosed or taken out without authorization. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 8.12.

You are reading one control. How much of ISO 27001:2022 have you already done?

ISO 27001:2022 8.12 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27001:2022 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 79 of 93 ISO 27001:2022 controls already carry evidence.
