23 NYCRR 500 Details
What It Is
23 NYCRR Part 500 is a mandatory regulation from the New York Department of Financial Services (NYDFS) establishing minimum cybersecurity standards for financial services entities. Its primary purpose is to protect nonpublic information (NPI) and ensure operational integrity through a risk-based cybersecurity program. The approach emphasizes governance accountability, evidence-based compliance, and phased implementation post-2023 amendments.
Key Components
- Core pillars: governance (CISO appointment), risk assessments, technical controls (MFA, encryption, access privileges), TPSP oversight, testing (penetration testing, vulnerability scans), incident response, and annual certification.
- 14 main requirements across sections like 500.2 (Cybersecurity Program) to 500.17 (Notifications).
- Built on risk assessment foundation; Class A companies face enhanced obligations like independent audits.
- Compliance via dual CEO/CISO certification filed April 15, with 5-year record retention.
Why Organizations Use It
Covered entities comply to avoid multimillion-dollar fines (e.g., Robinhood $30M). Benefits include reduced incident risk, stronger vendor contracts, board-level resilience, and alignment with NIST CSF.
Implementation Overview
Full implementation required as of Nov 2025 (including universal MFA); ongoing compliance involves gap analysis, asset inventory, policy updates. Applies to NY-licensed financial firms; no certification but DFS examinations enforce via consent orders.
MAS TRM Details
What It Is
MAS Technology Risk Management (TRM) Guidelines (revised January 2021) are supervisory guidelines issued by the Monetary Authority of Singapore (MAS) for financial institutions (FIs). They provide principles-based guidance on managing technology and cyber risks, emphasizing proportional implementation based on risk profile, complexity, and criticality to ensure confidentiality, integrity, and availability (CIA) of systems and data.
Key Components
- 15 main sections covering governance, risk frameworks, secure development, IT operations, resilience, access controls, cryptography, cyber defense, assessments, and audit.
- Synthesised into 12 core principles like board accountability, asset management, third-party oversight, and defence-in-depth.
- No fixed control count; focuses on outcomes with independent assurance via audit.
Why Organizations Use It
- Meets MAS supervisory expectations to avoid enforcement actions like fines or license issues.
- Enhances cyber resilience, operational stability, and customer trust.
- Supports digital transformation while managing third-party and ecosystem risks.
Implementation Overview
- Risk-based approach: asset inventory, risk assessment, control design, testing.
- Applies to all MAS-supervised FIs (banks, insurers, fintechs) proportionally.
- No formal certification; demonstrated through internal audits, board reporting, and MAS inspections.
