Three federal banking regulators issued a rule Thursday that requires banks and other financial institutions to notify their regulator within 36 hours of a “computer-security incident” that materially affects their operation, ability to deliver services, or the stability of the financial sector.
The Office of the Comptroller of the Currency (OCC), Federal Reserve, and Federal Deposit Insurance Corp. (FDIC) approved the policy, which also requires service providers for financial institutions to notify affected bank customers of any service outage caused by a computer-security incident that lasts longer than four hours.
