Notes on NIST Risk Management Framework (RMF)

National Institute of Standards and Technology (NIST)

  • NIST provides frameworks utilized by security professionals for managing risks, threats, and vulnerabilities.

Risk Management Framework (RMF)

  • Focus on NIST's Risk Management Framework (RMF).

  • Important for entry-level analysts to be familiar with RMF steps to enhance job readiness and stand out in the job market.

Overview of the RMF Steps

  • The RMF consists of seven steps:

    1. Prepare

    2. Categorize

    3. Select

    4. Implement

    5. Assess

    6. Authorize

    7. Monitor

Step 1: Prepare

  • Definition: Activities necessary to manage security and privacy risks pre-breach.

  • Role for Analysts: Monitor for risks and identify controls to reduce risks.

Step 2: Categorize

  • Definition: Develop risk management processes and tasks based on confidentiality, integrity, and availability (CIA) principles.

  • Role for Analysts: Understand and follow organizational processes to mitigate risks, especially for critical assets (e.g., private customer information).

Step 3: Select

  • Definition: Choose, customize, and document controls that protect the organization.

  • Example: Keeping an up-to-date playbook or managing documentation for efficient issue resolution.

Step 4: Implement

  • Definition: Execute security and privacy plans to minimize ongoing risks.

  • Example: Adjusting password requirements if frequent resets are observed among employees.

Step 5: Assess

  • Definition: Determine correctness of control implementations.

  • Importance: Ensures organizational efficiency by analyzing existing protocols and controls to meet needs.

  • Role for Analysts: Identify weaknesses and recommend changes for better risk management.

Step 6: Authorize

  • Definition: Accountability for existing security and privacy risks.

  • Role for Analysts: Generate reports, develop action plans, and establish project milestones aligned with security goals.

Step 7: Monitor

  • Definition: Continuous awareness of how systems operate and assessing technical operations daily.

  • Importance: Ensures low risk levels by confirming systems align with security goals.

  • Role for Analysts: Ensure working procedures are effectively managing risks to the organization and served individuals.
