    ISO 27701 Details

    What It Is

    ISO/IEC 27701:2025 is an international standard establishing requirements for a Privacy Information Management System (PIMS). It provides a certifiable framework for managing PII lifecycle, emphasizing accountability, risk management, and alignment with privacy laws like GDPR. Adopting a risk-based PDCA (Plan-Do-Check-Act) methodology, it extends management system principles.

    Key Components

    • Clauses 4–10 covering context, leadership, planning, support, operation, evaluation, improvement.
    • **Annex A/BRole-specific controls for PII controllers/processors (e.g., DSR handling, DPIAs, transfers).
    • Mappings to ISO 27001/27002, GDPR (Annex D), others.
    • Statement of Applicability (SoA) and records like RoPA for certification.

    Why Organizations Use It

    • Demonstrates compliance, reduces regulatory fines, breach risks.
    • Enhances trust, procurement differentiation, insurance benefits.
    • Harmonizes multi-jurisdiction privacy efforts.

    Implementation Overview

    Follow phased PDCA: scope, gap analysis, controls, audits. Applies to all sizes/sectors handling PII. Certification via accredited bodies, 3-year cycle with surveillance audits. (178 words)

    NERC CIP Details

    What It Is

    NERC Critical Infrastructure Protection (CIP) standards are mandatory reliability regulations developed by the North American Electric Reliability Corporation (NERC) and enforced by FERC. They protect the Bulk Electric System (BES) from cyber and physical threats that could cause misoperation or instability, using a risk-based, tiered approach categorizing assets as high, medium, or low impact.

    Key Components

    • Core standards: CIP-002 (scoping) to CIP-014 (supply chain/physical security)
    • **Pillarsgovernance (CIP-003), personnel (CIP-004), perimeters (CIP-005/006), system security (CIP-007), response/recovery (CIP-008/009/010)
    • ~14 standards with requirements like 35-day patching, 90-day log retention
    • Compliance via annual audits, evidence retention (3 years), penalties

    Why Organizations Use It

    • Legal mandate for BES owners/operators to avoid fines up to $1M+
    • Mitigates grid instability risks, enhances resilience
    • Builds stakeholder trust, lowers insurance costs
    • Strategic edge in reliability-focused markets

    Implementation Overview

    • Phased: scoping, gap analysis, controls, audits
    • Applies to utilities/transmission entities in US/Canada/Mexico
    • Involves OT/IT integration, training, documentation; multi-year for maturity
