Frameworks & standards

Access reviews are the floor.
Whocan evidences what they can't see.

Every major framework expects you to review who has access. Whocan answers that — then keeps going: privilege-escalation paths, cross-account trust, data-perimeter breaches, and separation-of-duties conflicts the periodic review never surfaces.

What each framework expects — and where Whocan goes further

The access-review requirement is the common floor. The right-hand column is what Whocan adds on top of it.

Framework / standardWhat the text requires on access reviewTypical cadenceHow Whocan goes further
ISO/IEC 27001:2022 & 27002:2022Annex A 5.18 (access rights) and 27002 8.2 (privileged access rights): provision and regularly review access; review privileged rights more often.Quarterly to annual; privileged more frequent Access-review inventory + privileged-role escalation paths
SOC 2 (Trust Services Criteria)CC6.2/CC6.3: access is authorized, modified or removed as roles change, and periodically reviewed for appropriateness.At least annual; quarterly for key systems Who-can inventory + change ledger as audit evidence
NIST SP 800-53 Rev. 5AC-2(j): review accounts at an organization-defined frequency. AC-2(7): manage and monitor privileged roles.Org-defined; quarterly common Account & entitlement review + privileged-role monitoring
NIST CSF 2.0PR.AA-05: permissions, entitlements, and authorizations are defined, enforced, and reviewed — including least privilege and separation of duties.Org-defined; routine evidence expected Least-privilege & SoD analysis across the full chain
CIS Controls v8Control 6.8: define, maintain, and review role-based access to validate privileges, at minimum annually.Annual minimum; more for high risk Recurring access reviews saved as monitors
GDPRArticles 5 and 32: data minimization and appropriate security. Periodic access review is a recognized means to meet them.Risk-based; document the rationale Who can reach personal-data stores, end to end
HIPAA Security Rule164.308(a)(4): authorize access by role; 164.308(a)(8): periodically evaluate it.Org-defined; at least annual commonly seen Access-to-ePHI inventory + periodic evidence
NIS2Article 21(2)(i): access-control policies; 21(2)(j): multi-factor authentication. Frequency is risk-based per national guidance.Risk-based, aligned to sectoral guidance Access-control inventory + MFA-condition gaps
DORA (EU) 2022/2554Article 9(4)(c): limit access to ICT assets to what legitimate functions require. Article 28: manage ICT third-party risk across the arrangement lifecycle, with a register of information.Risk-based; in application since Jan 2025 Article-mapped evidence — critical-data access, third-party reach, SoD, backup tampering
PCI DSS v4.07.2.4: review all user accounts and access every 6 months. 7.2.5.1: review system/service accounts at a risk-defined frequency.6 months (users); risk-based (system) User & service-account review, scoped to the CDE

Beyond the access review

What the periodic review can't see

A quarterly export tells you who has access today. It can't tell you who can get access — across accounts, through a chain nobody designed. That's the gap Whocan closes, and it closes it continuously.

Privilege-escalation chains

Multi-hop paths — user to role to role to admin — that no single-policy review reveals.

Cross-account & third-party trust

Every role assumable from another account or a vendor, with the trust statement that allows it.

Data-perimeter validation

Identity, resource, and network at once — only trusted identities, from expected networks, reach sensitive data.

Separation of duties & least privilege

Toxic-combination and over-privilege detection expressed as your own rules, not a fixed vendor list.

Continuous evidence

Saved queries re-run on every refresh; a snapshot diff becomes an auditor-grade change ledger — point-in-time or continuous.

Scope of this mapping

Whocan provides analysis and evidence to support your compliance program. It is not a certification, attestation, or legal advice, and using it does not by itself make an organization compliant. Control selection, review cadence, and scope remain yours to define with your auditor or assessor. Framework and standard names are the property of their respective owners; references here are for interoperability and do not imply endorsement.
