ISO 27001:2022 8.23: Web filtering

The organization is to manage which external websites can be reached, so that exposure to malicious content falls. Purpose (stated in ISO/IEC 27002:2022): keeps malware off systems and blocks unauthorized web resources. 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 8.23.

Other controls in Technological controls – ISO 27001:2022

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

ISO 27001:2022 8.23 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.

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. 170 were rejected on the NIST SP 800-53 Rev 5 pair alone.
