Why it matters
NYDFS reviews risk assessments during examinations and investigations, and its September letter says what examiners keep finding. It creates no new obligations. It explains what Part 500 already requires: a documented risk assessment that is good enough to shape the cybersecurity program, and a program that is actually built on it.
