NIST CSF Details
What It Is
NIST Cybersecurity Framework (CSF) 2.0 is a voluntary, risk-based guideline for organizations to manage cybersecurity risks. Developed by NIST, it provides a flexible structure applicable to any size, sector, or maturity level, emphasizing outcomes over prescriptive controls.
Key Components
- **Framework CoreSix functions (Govern, Identify, Protect, Detect, Respond, Recover), 22 categories, 112 subcategories with informative references to standards like ISO 27001.
- **Implementation TiersFour levels (Partial to Adaptive) for assessing risk management sophistication.
- **ProfilesCurrent and Target alignments for prioritization. No formal certification; self-attestation used.
Why Organizations Use It
Enhances risk communication, prioritizes investments, demonstrates due care, integrates with enterprise risk management, builds stakeholder trust, and addresses supply-chain threats. Mandatory for U.S. federal agencies; voluntary elsewhere.
Implementation Overview
Create Current/Target Profiles, conduct gap analysis, select Tiers. Involves policy development, training, monitoring. Suited for all organizations globally; quick starts for SMEs via guides and tooling.
GDPR UK Details
What It Is
UK GDPR (UK General Data Protection Regulation) is the UK's post-Brexit adaptation of the EU GDPR, a binding regulation enforced by the ICO. It establishes a risk-based, accountability-focused framework for protecting personal data of UK individuals, applying to controllers and processors established in the UK or targeting UK data subjects extraterritorially.
Key Components
- Seven core processing principles (lawfulness, purpose limitation, minimisation, accuracy, storage limitation, integrity/confidentiality, accountability).
- Individual rights (access, rectification, erasure, portability, objection).
- Controller/processor obligations (RoPAs, contracts, DPIAs, security, breaches).
- No formal certification; compliance demonstrated via documentation and audits, with fines up to 4% global turnover.
Why Organizations Use It
Mandated for legal compliance; mitigates fines (£17.5M max), reputational harm, civil claims. Enhances trust, operational efficiency via data governance, and supports cross-border business.
Implementation Overview
Phased approach: gap analysis, RoPA mapping, policies/contracts, training, DPIAs, monitoring. Applies to all sizes handling personal data; ICO enforces via investigations, no certification needed.
