Physical access to facilities and protected information assets is restricted to authorized personnel.
Also written as CC 6.4, TSC CC6.4, SOC2 CC6.4, SOC 2 Type 2 CC6.4.
Physical access restriction is one of 8 criteria in the Logical and Physical Access Controls (CC6) series of the Security (Common Criteria) category. Physical access to facilities and protected information assets is restricted to authorized personnel. CC6 is the heaviest-tested series in most SOC 2 reports and the one where exceptions most often appear — expect user access reviews, provisioning and deprovisioning tickets, and configuration exports to be sampled across the full period.
When preparing for a SOC 2 audit against CC6.4, gather artefacts such as:
CC6.4 corresponds to the following ISO 27001:2022 Annex A control(s): A.7.1, A.7.2, A.7.3, A.7.4, A.7.6, A.7.7, A.7.8, A.7.9, A.7.12, A.7.13. If you already run an ISO 27001 ISMS, map your existing evidence for these controls to CC6.4 rather than duplicating work.
Yes. CC6.4 sits in the Common Criteria, which apply to every SOC 2 engagement regardless of which additional categories you scope in — there is no SOC 2 report that omits them.
In a Type 1 report the auditor assesses design only — does a control exist at a point in time that would meet CC6.4 if it operated. In a Type 2 report they also test operating effectiveness by sampling evidence from across the review period, typically 3 to 12 months. That difference is why Type 2 evidence has to be continuous rather than assembled the week before fieldwork.
A control that fails becomes an exception, which the auditor describes in the report along with management's response. Exceptions do not automatically make a report "failed" — a SOC 2 report is an opinion, not a pass/fail certificate — but a qualified opinion is what customers notice, so remediate and re-test before fieldwork closes where you can.
Yes — CC6.4 aligns with ISO 27001:2022 Annex A control(s) A.7.1, A.7.2, A.7.3, A.7.4, A.7.6, A.7.7, A.7.8, A.7.9, A.7.12, A.7.13. If you already run a certified ISMS, re-point that evidence rather than building a parallel set; the underlying control is the same and only the reporting format differs.
