SOC 2 access control: are your governance controls keeping up?

TL;DR: SOC 2 access control policies still struggle with least privilege, just-in-time provisioning, access reviews, and unused access removal across complex systems, according to Zluri. The hard part is not the policy language but the governance machinery needed to keep access current as identities, roles, and systems change.

NHIMG editorial — based on content published by Zluri: SOC 2 Access Control: Challenges & Implementation

By the numbers:

• Only 5.7% of organisations have full visibility into their service accounts.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
• 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.

Questions worth separating out

Q: How should security teams implement least privilege in SOC 2 access control programmes?

A: Start with a live entitlement map that ties roles and attributes to actual business tasks, then remove broad defaults that are not strictly needed.

Q: When does just-in-time access create more governance value than static access grants?

A: Just-in-time access is most valuable when privileges are high-risk, infrequently used, or difficult to justify as standing access.

Q: What do organisations get wrong about periodic access reviews?

A: They often treat the review itself as the control instead of the remediation that follows it.

Practitioner guidance

• Map access to live business need Rebuild the access control matrix from current roles, systems, and data classifications so approvals are based on today’s operating model rather than legacy job titles.
• Convert high-risk grants to JIT workflows Use just-in-time provisioning for privileged and sensitive access, with automatic expiry and logged revocation so permissions do not become standing privilege.
• Remove unused access on a fixed cadence Run scheduled reviews to identify dormant entitlements, orphaned accounts, and permissions no longer tied to active projects or customers, then revoke them promptly.
