NIST Risk Management Framework (RMF) For Small Enterprise

Lay the groundwork for implementing the NIST RMF through the prepare step, establishing objectives, roles, scope, and key terms like authorization boundary, system boundary, risk tolerance, and risk assessment.

Assign a responsible individual or team, internal or external, to execute the RMF, oversee from preparation to monitoring, and align with goals and risk tolerance, with executive support.

Create a dynamic risk management strategy that defines risk tolerance and thresholds and establishes assessment, response, and monitoring processes, guided by Sara Johnson, John Miller, and Secure Tech Consulting.

Identify the system's scope of protection and authorization boundaries, covering hardware, software, data, and people, to guide risk management and security controls across internal networks, cloud services, and external interfaces.

Define the system's protection scope by mapping hardware, software, data, processes, users, and interfaces, establishing authorization boundaries, and applying consistent security controls across all included assets.

regularly assess security and privacy risks at organizational and system levels, identify and prioritize threats, and update results to align with evolving threat landscapes and the risk management framework.

Categorize the system and information to determine impact, then select an initial set of controls and tailor the baseline to risk, protecting confidentiality, integrity, and availability.

Categorize each system by the potential impact on confidentiality, availability, and integrity to prioritize protection, highlighting high and medium impact assets like crm, data storage, and networks.

Select and implement impact-based controls to safeguard high and medium systems, using MFA, RBAC, encryption, backups, training, WAF, SSL/TLS, and continuous monitoring.

Tailor baseline controls to an organization’s risk assessments and privacy needs by enhancing encryption, refining access controls, and documenting the security and privacy plan.

Implement a system level strategy to monitor control effectiveness across core assets, using real-time logging, risk assessments, and regular reporting to maintain compliance and security.

Implement controls across infrastructure, guided by risk assessment and categorization, configuring, integrating, testing, and documenting to protect data at rest and in transit, coordinating with departments, and enabling continuous monitoring.

Update the security and privacy plans as part of step 11, reflecting RMF controls, documenting revisions, reviewing deployment, and communicating changes to stakeholders for audits.

Select an internal or external assessor with deep system knowledge and objectivity to conduct the control assessment, using a dual approach to uncover gaps and show RMF effectiveness.

Develop, review, and approve a detailed RMF plan to assess implemented controls, outlining objectives, scope, methodologies, and success criteria, and secure stakeholder approval to guide a comprehensive risk management assessment.

Carry out the control assessments per approved plans in step 14 (task a-3), testing security and privacy controls via penetration testing, vulnerability scanning, and manual reviews to verify effectiveness.

Prepare an assessment report detailing findings, analysis, and recommendations from the RMF task A-4 control assessment, outlining scope, vulnerabilities, and next steps for remediation and monitoring.

Prepare the step 16 plan of action and milestones (poa&m) for task a-6 by translating assessment findings into prioritized remediation tasks with timelines, responsibilities, and contingency measures for RMF.

Assemble the rmf authorization package, including executive summary, ssp, control assessment reports, poa&m, security and privacy controls, and risk mitigation plans, to support the authorization decision.

The authorizing official analyzes the authorization package to determine residual risk, evaluate control assessments and risk analyses, and decide if MFA and patching issues warrant conditional authorization.

Review the authorization package and system risks to decide if operation aligns with acceptable risk levels. Issue an authorization decision - full, conditional, or denial - and ensure continuous monitoring.

Monitor the system and its environment continuously to protect security and privacy. Implement continuous monitoring to assess controls against upgrades, personnel changes, and external threats, including zero trust reforms.

Leverage continuous monitoring results to decide on risk responses, reassess vulnerabilities, and update the plan of action and milestones, ensuring timely mitigations and proactive security leadership.

Maintain ongoing leadership communication to keep the security and privacy posture transparent, with concise reports on controls, assessments, and incidents, enabling informed risk decisions and resource actions.

Apply the NIST RMF for small enterprise by following preparing, categorizing, selecting, implementing, assessing, and monitoring controls while addressing MFA vulnerabilities and phishing through stakeholder collaboration.
