NIST Cybersecurity Framework (NIST CSF) Overview
NIST Cybersecurity Framework (NIST CSF) Overview
What is the NIST Cybersecurity Framework?
The NIST Cybersecurity Framework (CSF) is a voluntary, risk-based approach developed by the National Institute of Standards and Technology (NIST) to help organizations of all sizes manage and reduce cybersecurity risk. It is widely used in both public and private sectors.
Category:
- Cybersecurity
- Risk Management
- Compliance and Governance
Use Cases:
- Assessing and improving cybersecurity posture
- Regulatory compliance (e.g., HIPAA, FISMA, CMMC)
- Aligning IT security with business strategy
- Vendor risk management
Who Uses It?
- U.S. federal agencies (required by Executive Order 13800)
- Critical infrastructure organizations (e.g., energy, finance)
- Enterprises and SMBs across all sectors
- Managed Security Service Providers (MSSPs)
Core Features of NIST CSF
- Five Core Functions: Identify, Protect, Detect, Respond, Recover
- Implementation Tiers: Describe how cybersecurity risk is managed (Tier 1–4)
- Profiles: Customizable roadmap for aligning practices with goals
- Categories & Subcategories: Specific technical and organizational practices
- Integration-Friendly: Maps to ISO 27001, COBIT, CIS Controls, etc.
