The National Institute of Standards and Technology (NIST) has established the Risk Management Framework (RMF) as a way to help organizations operate securely. It’s a process that integrates security, privacy, and cyber supply chain risk management into the system development life cycle.
As a risk-based framework, RMF provides a structured, repeatable, and measurable process for identifying, assessing, and mitigating risks to information systems and organizational assets. Net result: RMF helps organizations manage their cybersecurity risks and to ensure compliance.
Here, we’ll look at the steps of the NIST RMF and its benefits.
What is the NIST RMF?
The NIST Risk Management Framework (RMF) describes the processes agencies must use to implement, manage, and monitor cybersecurity capabilities and services. It aims to establish a disciplined and structured approach to managing cybersecurity risks.
RMF helps with legal and regulatory compliance and enhances the overall security posture of organizations’ information systems. Combining IT security and risk management into the systems development lifecycle provides a systematic process for identifying, assessing, and mitigating risks.
The Seven Steps of the NIST RMF
The NIST RMF is defined by certain key steps:
Step 1: Prepare
This foundational step involves establishing a comprehensive understanding of the organization’s risk tolerance, resources, and environment. Activities include defining roles and responsibilities, establishing a risk management strategy, and determining the scope of the RMF process. This sets a solid foundation for all subsequent steps.
Step 2: Categorize Information Systems
In RMF, categorization connects an information system’s security activities to an organization’s business priorities and mission. Categorization involves assessing the potential impact of an information system on an organization’s assets, individuals, mission, or other organizations. Factors to consider include:
- Information types
- The potential impact (loss of confidentiality or a threat to security, for example)
- The security objectives for a given system
Step 3: Select Security Controls
The guiding document in RMF is the NIST Special Publication 800-53. It defines a set of security and privacy controls developed by NIST to help government agencies protect their information systems. Guided by this document, organizations can select appropriate controls depending on the sensitivity and criticality of their systems and data.
Step 4: Implement Security Controls
To implement controls in NIST RMF, organizations can identify risk management roles and responsibilities, define organization-level risk management and continuous monitoring strategies, and complete other organization-level tasks. They will also establish common controls and organizational policies, processes, and procedures.
As noted above, some tools and resources that can aid the implementation of NIST RMF include NIST SP 800-37, which offers official RMF guidance, and NIST SP 800-53, which offers a catalog of security controls.
Step 5: Assess Security Controls
To ensure success, organizations will need to assess the effectiveness of their controls in NIST RMF. In this process, an assessor will examine or analyze current security controls, interview the employees who engage with these controls, and test to verify that the controls are working properly.
NIST 800-30 outlines the basic steps for conducting a risk assessment, which can be applied to security risk assessments in general. These steps include:
- Identifying threat sources and events,
- Identifying vulnerabilities and predisposing conditions
- Determining the likelihood of occurrence
- Determining the magnitude of impact
- Determining risk
Step 6: Authorize Information System
The authorization process in the NIST RMF requires a senior management official to determine whether the security, privacy, and supply chain risks associated with a system’s operation or common controls are acceptable. This includes risks to organizational operations and assets, individuals, other organizations, or the nation.
Step 7: Monitor Security Controls
In RMF, continuous monitoring is a strategy for actively observing, assessing, and reporting on the security status of a system or network. Done on an ongoing basis, continuous monitoring offers a proactive approach to security.
Once a system has been authorized to operate, organizations will need to monitor its security posture continuously. This involves regular reviews of security controls, assessing any changes or updates to the system, and monitoring for any potential security incidents or breaches.
Implementing the NIST RMF in Your Organization
To implement NIST RMF effectively, start by gaining executive buy-in and clear communication across teams. Build a centralized risk management team with RMF champions in each department, and conduct an initial gap analysis to assess resource needs. Define risk tolerance with leadership and create a tailored risk policy that aligns with business goals. Integrate RMF with any existing frameworks, streamline compliance, and invest in tools for automation and efficient reporting. Provide continuous training to foster awareness, and establish a roadmap for ongoing RMF improvement and adaptability.
