Annex A 8.3
Information access restriction
Access to information and other associated assets is restricted in accordance with the access control policy.
What an assessor looks for
Assessors sample: they pick a sensitive repository and ask who can reach it and why. Broad inherited permissions in collaboration platforms are a frequent weak point.
Where it usually fails
Shared drives and collaboration sites are open to all staff because restricting them retrospectively was judged too disruptive.
