NIST CSF Details
What It Is
NIST Cybersecurity Framework 2.0 (CSF 2.0) is a voluntary, risk-based guideline developed by NIST for managing cybersecurity risks. It provides a flexible structure applicable to organizations of any size or sector, emphasizing outcomes over prescriptive controls. Its risk-based approach uses high-level Functions, Categories, and Subcategories to align security with business objectives.
Key Components
- **Six Core FunctionsGovern (new), Identify, Protect, Detect, Respond, Recover (112 Subcategories total).
- **Implementation TiersPartial (Tier 1) to Adaptive (Tier 4) for maturity assessment.
- **Framework ProfilesCurrent vs. Target for gap analysis.
- Built on industry standards with informative references to ISO 27001, NIST SP 800-53. No formal certification; self-attestation suffices.
Why Organizations Use It
Enhances risk communication, prioritizes investments, demonstrates due care. Supports compliance (mandatory for U.S. federal), supply chain management, stakeholder trust. Provides common language for executives and technical teams, fostering strategic alignment.
Implementation Overview
Create Profiles, assess Tiers, map to existing controls. Involves gap analysis, policy development, tooling integration. Suited for all sizes/industries globally; quick starts via guides, full maturity 6-12 months with vendors.
ISO 22301 Details
What It Is
ISO 22301:2019 is the international standard specifying requirements for a Business Continuity Management System (BCMS). It provides a flexible, risk-based framework using the PDCA (Plan-Do-Check-Act) cycle to protect against, reduce the likelihood of, and ensure recovery from disruptions like cyberattacks, pandemics, and natural disasters.
Key Components
- 10 clauses aligned with Annex SL high-level structure: context (Clause 4), leadership (5), planning with BIA and RA (6), support (7), operation including testing (8), performance evaluation (9), improvement (10).
- No prescriptive controls; adaptable to organizational needs.
- Certification model: 3-year validity with annual surveillance audits.
Why Organizations Use It
- Builds resilience, minimizes downtime and financial losses.
- Meets regulatory demands (e.g., NIS Directive, NIST).
- Enhances reputation, stakeholder trust, insurance savings, competitive edges.
- Supports integrated management with ISO 27001.
Implementation Overview
- Step-by-step: gap analysis, BIA, policy development, training, testing, audits.
- Applicable to all sizes, sectors, geographies.
- Two-stage certification process (6-8 weeks); tools accelerate deployment.
