The Federal Financial Institutions Examination Council (FFIEC) is the inter-agency body of the United States government that prescribes uniform principles, standards and report forms for the federal examination of financial institutions. It is empowered by various entities including the Board of Governors of the Federal Reserve System (FRB), the Federal Deposit Insurance Corporation (FDIC), the National Credit Union Administration (NCUA), the Office of the Comptroller of the Currency (OCC) and the Consumer Financial Protection Bureau (CPFB).

The FFIEC makes recommendations to promote uniformity in the supervision of financial institutions. Regulated financial institutions must comply with the guidelines of FFIEC consistent with the Gramm-Leach-Bliley Act of 1999 (GLBA). FFIEC documented the necessary controls for compliance in the “FFIEC Information Security Handbook” and subsequently provided a cybersecurity assessment tool to help financial institutions improve their cybersecurity postures.

Complying with FFIEC/NCUA guidance can challenge financial institutions that have limited resources, but Arctic Wolf helps organizations meet many of the FFIEC/NCUA requirements with a turnkey SOC-as-a-service solution—the AWN CyberSOC™ service. This document maps the specific control requirements in the FFEIC Information Security handbook to the AWN CyberSOC.

Who Is Affected

The FFIEC/NCUA guidance and supervision affects federally supervised financial institutions, their holding companies, and the nonfinancial institution subsidiaries of those institutions and holding companies. This includes banks insured by the FDIC, credit unions supervised by the NCUA, national banks and their subsidiaries supervised by the OCC.
