Cybersecurity Briefing — April 29, 2025

Executive briefing: The New York State Department of Financial Services (NYDFS) second amendment to 23 NYCRR 500 set April 29, 2025 as the compliance deadline for the 18-month transition requirements. Covered entities must evidence enhanced privileged access controls, continuous monitoring, independent audits, and asset inventory programs. Zeph Tech is helping CISOs and compliance officers sequence remediation before NYDFS escalates supervisory actions.

Key regulatory requirements

Privileged access governance (Section 500.7). Entities must enforce multi-factor authentication for privileged accounts, implement password vaulting, and monitor anomalous privilege escalation.
Automated monitoring (Section 500.14). Continuous monitoring or at minimum weekly vulnerability assessments are mandatory, alongside documented risk-based remediation timelines.
Asset inventories (Section 500.13). Maintain accurate inventories of information systems, data, and key third parties including classification, ownership, and lifecycle metadata.
Independent audits (Section 500.11). Class A companies must undergo independent cybersecurity audits at least annually; other covered entities need documented risk-based audit cadences.

Control alignment

NIST CSF 2.0. Map NYDFS controls to Identify (ID.AM) for asset management, Protect (PR.AA) for privilege governance, and Detect (DE.CM) for continuous monitoring.
ISO/IEC 27001:2022 Annex A. Align with controls A.5.15 (access rights), A.8.16 (monitoring activities), and A.5.30 (supplier relationships).
FFIEC CAT. Financial institutions can reuse inherent risk and maturity assessments to track NYDFS readiness across domains.

Implementation priorities

Complete privileged access management deployments with session recording, just-in-time elevation, and automated reconciliation.
Deploy continuous monitoring platforms (EDR, SIEM, vulnerability management) with documented escalation paths and board reporting.
Establish configuration baselines for asset inventories, linking CMDB records to data classification and recovery objectives.

Enablement moves

Update board cyber reports to include NYDFS key risk indicators and remediation status for April 2025 milestones.
Rehearse incident escalation with legal and compliance teams to meet the 72-hour notification and 90-day remediation reporting requirements.
Coordinate with internal audit or third parties to scope the first annual independent audit, ensuring evidence repositories are structured for rapid sampling.
