NERC CIP Details
What It Is
NERC CIP (North American Electric Reliability Corporation Critical Infrastructure Protection) is a suite of mandatory Reliability Standards for cybersecurity and physical security of the Bulk Electric System (BES). Its primary purpose is to prevent compromise leading to BES misoperation or instability, using a risk-based tiering approach categorizing BES Cyber Systems as High, Medium, or Low impact.
Key Components
- Core standards: CIP-002 (scoping), CIP-003 (governance), CIP-004 (personnel), CIP-005/006 (perimeters), CIP-007 (system security), CIP-008-010 (response/recovery/configuration).
- Recurring cycles: 15-month reviews, 35-day patching/monitoring, 90-day log retention.
- Built on CIP Senior Manager accountability and annual audits by NERC/FERC.
Why Organizations Use It
- Legal mandate for BES owners/operators; non-compliance risks million-dollar fines.
- Enhances grid reliability, reduces outage risks, lowers insurance premiums.
- Builds stakeholder trust via proven resilience.
Implementation Overview
Phased approach: asset inventory (CIP-002), policy development, technical controls, testing. Applies to utilities/transmission entities in US/Canada/Mexico; enforced via audits, no certification but continuous evidence retention.
23 NYCRR 500 Details
What It Is
23 NYCRR Part 500 is the New York Department of Financial Services (NYDFS) Cybersecurity Regulation, a state-level mandate for financial entities. It establishes minimum risk-based cybersecurity requirements to protect nonpublic information (NPI) and information systems, applying to Covered Entities like banks, insurers, and licensees operating in New York.
Key Components
- 14 core requirements including cybersecurity program, CISO appointment, risk assessments, MFA, encryption, penetration testing, TPSP oversight, and incident response.
- Built on risk assessment-centric architecture with annual CISO/CEO dual certification and five-year record retention.
- Phased compliance for Class A companies with enhanced audits and controls; no formal certification but NYDFS examinations and enforcement.
Why Organizations Use It
- Mandatory for NY-licensed financial firms to avoid multimillion-dollar fines (e.g., Robinhood $30M).
- Enhances resilience, reduces incident risk, builds stakeholder trust, and aligns with NIST CSF.
Implementation Overview
- Cross-functional roadmap: gap analysis, asset inventory, policy updates, technical controls (phishing-resistant MFA, PAM), TPSP contracts, IR testing.
- Applies to NY financial services entities; phased timelines up to 24 months; evidence repository for annual April 15 filing.
