They should use a risk-based framework such as NIST CSF 2.0 or CRI Profiles, then map identity, access, and third-party controls to live operational evidence. The replacement should show who has access, how that access is reviewed, and whether termination actually revokes entitlements. A scoring model alone is no longer enough.
Why This Matters for Security Teams
The FFIEC CAT was useful as a transitional questionnaire, but it is no longer strong enough as a governance model for institutions that need evidence of control performance, not just self-attestation. Financial firms now operate with cloud services, SaaS integrations, third-party OAuth connections, and machine identities that shift faster than annual or point-in-time assessments can capture. That is why current guidance increasingly points toward NIST Cybersecurity Framework 2.0 and operational control mapping instead of score-based maturity alone.
This matters most where access reviews, termination, and third-party oversight are treated as paper processes. If an identity still has access after a role change, vendor offboarding, or service decommissioning, the institution may have a governance answer but not a security control. NHIMG research on The State of Non-Human Identity Security found that only 1.5 out of 10 organisations are highly confident in securing NHIs, which is a strong signal that confidence and actual control performance often diverge.
In practice, many security teams discover control gaps only after a vendor connection, dormant account, or over-privileged service identity has already been abused, rather than through intentional governance testing.
How It Works in Practice
A more current model starts with outcomes and evidence. Rather than asking whether a control exists, the institution should ask whether it works today, for the identities that matter most. That includes human access, privileged access, service accounts, API keys, certificates, and third-party connections. The most practical approach is to map these controls to NIST CSF 2.0 functions, then collect live evidence from IAM, PAM, ITSM, cloud logs, and third-party risk systems.
For identity governance, NIST SP 800-63 Digital Identity Guidelines help anchor assurance and lifecycle expectations, while NHIMG’s Lifecycle Processes for Managing NHIs is useful for turning the abstract idea of identity governance into operational checkpoints. The key is to maintain evidence that answers four questions:
- Who has access, including third parties and non-human identities?
- Why was the access granted, and who approved it?
- How often is the access reviewed, and what was the last review outcome?
- Did termination, offboarding, or decommissioning actually revoke entitlements?
In practice, this means replacing static scoring with control telemetry. Examples include terminated users with no active sessions, service identities with short-lived secrets, vendors with no unused OAuth grants, and privileged accounts tied to ticketed approvals. Institutions should also retain audit trails that demonstrate not just access reviews, but timely remediation when reviews fail. Where the institution relies on third parties, the governance model should show whether those connections are inventoried, monitored, and removed when no longer needed. These controls tend to break down when identity data is fragmented across multiple directories, SaaS platforms, and unmanaged vendor integrations because no single system can prove effective revocation end to end.
Common Variations and Edge Cases
Tighter governance often increases operational overhead, requiring organisations to balance stronger evidence collection against audit fatigue and system complexity. That tradeoff is real in banks, insurers, and credit unions that run legacy directories alongside modern cloud identity platforms.
There is no universal standard for replacing the FFIEC CAT yet, so institutions should treat current guidance as a mapping exercise rather than a one-to-one substitute. Some firms will prefer CRI Profiles for sector-specific benchmarking, while others will use CSF 2.0 as the umbrella and layer internal control domains beneath it. The important point is not the label on the framework, but whether it can show control effectiveness for access, review, and revocation.
Edge cases matter. Joint ventures, outsourced operations, and embedded finance partnerships often create identity sprawl that is not visible in a single IAM console. In those environments, the institution should extend governance to SaaS tenants, API credentials, privileged service accounts, and delegated administrator roles. NHIMG’s Top 10 NHI Issues is especially useful when the risk problem is actually a coverage problem. For firms looking for a control narrative that auditors and supervisors can test, Regulatory and Audit Perspectives can help translate governance into evidence requirements.
The governance model breaks down when an institution still depends on annual attestations for fast-moving identities and assumes a passed score means access is actually controlled.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.OC-03 | Defines governance outcomes that fit a replacement for CAT scoring. |
| NIST SP 800-63 | IAL/AAL/FAL | Identity assurance helps anchor access review and revocation evidence. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Covers weak NHI lifecycle governance and stale credentials in institutions. |
Tie identity proofing and authentication assurance to lifecycle controls and termination checks.
