The New York State Department of Financial Services last week sent a memorandum to federal and state financial and insurance regulators announcing that it may issue new regulations “aimed at increasing cyber security defenses within the financial sector” and seeking “dialogue, collaboration and, ultimately, regulatory convergence among our agencies on new, strong cyber security standards for financial institutions.”  The memo indicates that the regulations would go much farther than the data security rules promulgated by federal agencies pursuant to the Gramm-Leach-Bliley Act.  Resistance from at least some federal agencies therefore seems likely.  But opposition from the feds has rarely stood in the way of aggressive New York regulators.
