A.8.3 Information access restriction

The organization is to limit who can reach information and associated assets, following its established access control policy. Purpose (stated in ISO/IEC 27002:2022): ensures only authorized access to information and associated assets and prevents unauthorized access. 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 8.3.

Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

  • Rules and configuration for dynamic access management or rights management on high-value information (identity, device, location, time limits, printing, encryption) · Endpoint management (MDM / EDR)

  • Evidence that anonymous or public access is limited to locations holding no sensitive information, for example storage bucket access reviews · Document repository

governing documentDocuments that govern the control

  • Statement of Applicability entry for control A.8.3, showing inclusion or justified exclusion, implementation status and the risks it treats · Policy repository / GRC workspace
  • System, application and cloud storage configurations restricting access by identity or group, with granular permissions per action · Policy repository / GRC workspace
  • Isolation of sensitive applications, data or systems through physical or logical segmentation · Policy repository / GRC workspace

First move

Mostly documents and reviews. Pull the 1 system-held artefact from your Endpoint management (MDM / EDR) on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
