NIST CSF Details
What It Is
The NIST Cybersecurity Framework (CSF) 2.0 is a voluntary, risk-based guideline from the U.S. National Institute of Standards and Technology. It provides a flexible structure to manage cybersecurity risks, applicable to organizations of any size, sector, or maturity level. Its methodology emphasizes outcomes over prescriptive controls, fostering a common language for risk discussions.
Key Components
- **Framework CoreSix functions (Govern, Identify, Protect, Detect, Respond, Recover) with 22 categories and 112 subcategories, linked to informative references like ISO 27001 and NIST SP 800-53.
- **Implementation TiersFour levels (Partial, Risk Informed, Repeatable, Adaptive) to evaluate risk management sophistication.
- **Framework ProfilesAlign Core outcomes with business needs via Current and Target states. No formal certification; relies on self-assessment.
Why Organizations Use It
- Enables prioritized risk reduction and supply chain management.
- Mandatory for U.S. federal agencies; demonstrates due care elsewhere.
- Improves executive communication, compliance alignment, and stakeholder trust.
- Supports continuous improvement and cost-effective security.
Implementation Overview
- Create Profiles, assess Tiers, prioritize gaps using existing controls.
- Scalable for SMEs via quick starts to enterprises with tooling.
- Global applicability; ongoing via workshops and community profiles.
ISO 31000 Details
What It Is
ISO 31000:2018, Risk management — Guidelines is an international standard providing non-certifiable guidance for enterprise-wide risk management.
