NIST SP 800-30 Risk Assessment: Step-by-Step

The Risk Assessment Process (Chapter 3)

1. Prepare for the assessment
2. Conduct the assessment (threats, vulnerabilities, likelihood, impact → risk)
3. Communicate results and share risk-related information
4. Maintain the assessment over time

Why It Matters

SP 800-30 remains a default citation for “NIST risk assessment methodology” in SSPs, CSF Profiles, and 800-171 programmes — even though the publication predates CSF 2.0 and SP 800-53 Rev 5.

How CyberSilo Helps

• Compliance Standards Automation — link risk register items to Profiles and controls
• ThreatSearch TIP and ThreatHawk SIEM — threat and vulnerability inputs to the Conduct step

Frequently Asked Questions

How does SP 800-30 relate to the RMF (SP 800-37)?

SP 800-30 details how to perform risk assessments within the broader risk management approach described by SP 800-39 and used by the Risk Management Framework (SP 800-37).

How does it relate to CSF Identify (ID.RA)?

Compatible outcome language. CSF ID.RA describes risk-assessment outcomes; SP 800-30 provides a structured assessment method.

Is SP 800-30 only for federal agencies?

It is written for federal systems and organizations but is widely adopted voluntarily by nonfederal organizations.
