Credit unions sometimes assume FFIEC guidance is a bank-only concern. It isn't. The FFIEC IT Examination Handbook is a joint framework adopted by the OCC, FDIC, Federal Reserve, and NCUA — meaning the same underlying access-review expectations apply to NCUA-supervised institutions, examined through NCUA's own process. Here's what that means in practice.
Same expectations, different examiner
The core principle behind the 2021 interagency guidance on Authentication and Access to Financial Institution Services and Systems is shared across all four agencies: identify every user, system, and service account that requires authentication controls; enforce least-privilege access; and recertify periodically with a documented process. NCUA examiners assess credit unions against this same baseline, even though the exam is run by a different agency than a bank's primary regulator.
Where credit unions should focus first
1. Vendor and CUSO access
Credit unions frequently rely on credit union service organizations (CUSOs) and third-party vendors for core processing, lending, and member services. Each of these relationships introduces access points that need to be inventoried and reviewed, not just internal employee accounts.
2. Volunteer board and committee access
Credit unions' volunteer board structure means access reviews sometimes need to account for board and committee members who have visibility into member data or systems — a category banks generally don't have to consider in the same way.
3. Shared branching and network access
Participation in shared branching networks can introduce access relationships that are easy to overlook in a standard employee-and-vendor inventory. These should be explicitly included in your system list.
4. Core platform and ancillary system coverage
As with banks, the most common gap is an incomplete system inventory — reviewing core platform access thoroughly while overlooking smaller ancillary applications that still touch member data.
The mechanics of a defensible access review are identical for a credit union and a community bank. The difference is which categories of access — vendor, CUSO, volunteer, shared branching — need to be on the inventory in the first place.
What this means for your next exam
If your access review process was built with only employees and a single core platform in mind, start by expanding the system and access-category inventory before worrying about the mechanics of the review itself. Once the inventory is complete, the same review, certification, and documentation approach used across community banking applies directly.
Building or refreshing your access inventory?
All Access IDM connects to your core platform, directory services, and ancillary systems to build that inventory once, not from scratch every cycle.
