NIST SP 800-30 provides a consistent, repeatable framework for identifying, analyzing, and evaluating organizational risks. It connects threats, vulnerabilities, likelihood, exploitability, and effects to control selection, prioritization, and residual-risk decisions. section 6.3
A practical assessment follows these concerns:
- Set the scope and define its assets, boundaries, systems, and data to prevent scope creep. section 6.3.1
- Identify realistic, current, and potential threats rather than exaggerated scenarios. section 6.3.1
- Determine vulnerabilities using software analysis and known CVEs, while recognizing that proprietary systems may lack entries. section 6.3.1
- Assess likelihood, exploitability, and effects; then prioritize controls and identify residual risks. section 6.3
