On November 18, 2021, the Federal Deposit Insurance Corporation (FDIC), the Board of Governors of the Federal Reserve System (FRB), and the Office of the Comptroller of the Currency (OCC) issued a joint final rule (the “Computer-Security Incident Rule” or the “Final Rule”) establishing computer-security notification requirements for banking organizations and their bank service providers.

Second, a “bank service provider” must notify each affected banking organization customer as soon as possible of a “computer-security incident” that has caused, or is reasonably likely to cause, a material service disruption or degradation for four or more hours. The purpose of the Computer-Security Incident Rule’s notification requirements is to provide earlier awareness of emerging threats to banking organizations and the broader financial system.
The Final Rule defines a “computer-security incident” as an occurrence that, “(i) results in actual or potential harm to the confidentiality, integrity, or availability of an information system or the information that the system processes, stores, or transmits; or (ii) constitutes a violation or imminent threat of violation of security policies, security procedures, or acceptable use policies.”

- A large scale distributed denial of service attack that disrupts customer account access for an extended period of time;
- A failed system upgrade or change that results in widespread user outages for customers and banking organization…
