Data breaches hit an all-time high in 2023, with many organizations experiencing multiple breaches. In fact, 95% of organizations surveyed by IBM between March 2022 and March 2023 said they had experienced more than one data breach. New cybersecurity risks, including cloud misconfigurations, more sophisticated ransomware, and vendor exploitation attacks, contributed to the increases in data breaches, according to an MIT report.

As the frequency and impact of data breaches and other cyber attacks continue to increase, organizations must implement robust risk management processes to secure a growing attack surface against evolving attack vectors and technologies.

One of the most respected frameworks for managing risks is the NIST Risk Management Framework (RMF). This comprehensive guide will delve into the NIST RMF, exploring its importance, steps, and best practices for implementation.

What is the NIST Risk Management Framework?

Created by the National Institute of Standards and Technology, the RMF is a comprehensive, flexible, repeatable, and measurable 7-step process aimed at integrating security and risk management activities into the system development life cycle. It provides a structured process that ensures information security and risk management are not afterthoughts but integral components of an organization’s overall mission and business processes.

Who does NIST RMF apply to?

NIST RMF can be applied to any type of organization. In addition to federal agencies, state, local, and tribal governments and private sector organizations across industries are encouraged to use this voluntary framework to better manage security and privacy risks.

The benefits of implementing the NIST RMF

NIST RMF is designed to help strengthen the underlying information systems, components, products, and services of any organization. 

Implementing NIST RMF offers benefits to all types of organizations, including:

  • Standardization: The RMF provides a standardized approach to risk management, ensuring consistency across various departments and systems and alignment with the organization’s mission and business objectives.
  • Compliance: By adhering to the RMF, federal agencies satisfy the requirements in the Federal Information Security Modernization Act of 2014 (FISMA), the Privacy Act of 1974, OMB policies, and Federal Information Processing Standards, among other laws, regulations, and policies. Following RMF guidelines also helps federal agencies as well as other organizations implement the NIST Cybersecurity Framework (CSF).
  • Security and privacy protections: The RMF ensures that security and privacy considerations are integrated into every phase of the system development life cycle and that appropriate risk response strategies are implemented. This helps achieve security protections for information and information systems and privacy protections for individuals.
  • Proactive security and privacy: The RMF’s emphasis on preparation and continuous monitoring promotes a proactive stance toward managing security and privacy risks.
  • Risk-based decision-making: By providing a structured approach to risk assessment, the RMF aids in better decision-making regarding resource allocation and risk mitigation strategies.
  • Tailored risk management: Encouraging the tailoring of controls ensures they are relevant and effective for the specific organizational context.

NIST 800-37 Rev 2

The RMF is detailed in NIST Special Publication 800-37, “Guide for Applying the Risk Management Framework to Federal Information Systems.” The latest version, NIST 800-37 Revision 2, builds on the foundation established by Revision 1, offering a more comprehensive and integrated approach to risk management.

Key changes in Revision 2 include:

  • The introduction of the Prepare step: The "Prepare" step was introduced in the updated version of the NIST Risk Management Framework, detailed in NIST Special Publication 800-37 Revision 2. This step aims to facilitate more effective, efficient, and cost-effective security and privacy risk management processes by laying the groundwork for the subsequent RMF steps.
  • The integration of privacy: Revision 1 focused primarily on information security. Recognizing the growing importance of privacy, Revision 2 integrates privacy risk management processes into the RMF to ensure organizations are building privacy protections into the risk management process alongside security. This includes identifying privacy risks and implementing controls to mitigate these risks.
  • The integration of supply chain risk management: Revision 2 also integrates security-related, supply chain risk management (SCRM) concepts into the RMF. This addition recognizes that supply chain risk is a growing concern to organizations as they increasingly rely on third-party providers and commercial off-the-shelf products, services and systems. 
  • Alignment with other NIST frameworks: Revision 2 aligns more closely with other NIST frameworks, such as NIST CSF and NIST Privacy Framework, to provide a more cohesive approach to risk management that can be applied across different sectors and frameworks.

NIST Risk Management Framework steps

The NIST RMF consists of seven steps that are critical to the framework's overall effectiveness.  Below you’ll find an overview of each step, including its purpose and series of associated tasks.   Each list of tasks is not exhaustive. You can find a complete list of tasks as well as expected outcomes in NIST SP 800-37.

It provides guidelines to help organizations manage information security and privacy risks effectively, ensuring that these considerations are incorporated into every phase of system development and operation.

What are the steps in the NIST RMF?

The NIST RMF consists of seven steps:

1. Prepare: Establish a foundation for subsequent RMF steps by defining roles, strategies, and conducting organization-level risk assessments.

2. Categorize: Categorize the system and information processed, stored, and transmitted based on an impact analysis.

3. Select: Select appropriate security and privacy controls based on the system's categorization.

4. Implement: Implement the selected controls within the information system. 

5. Assess: Assess the controls to ensure they are correctly implemented and effective.

6. Authorize: Make a risk-based decision to authorize the system to operate.

7. Monitor: Continuously monitor the system and its controls to ensure ongoing effectiveness and address new risks.

What is the purpose of the Prepare step introduced in NIST SP 800-37 Revision 2?

The purpose of the Prepare step is to carry out essential risk management tasks to establish context and help prepare the organization to manage its security and privacy risks using the NIST Risk Management Framework. It was introduced in NIST SP 800-37 to help organizations achieve more effective, efficient, and cost-effective security and privacy risk management processes. 

How does NIST SP 800-37 Revision 2 integrate privacy into the RMF?

Revision 2 emphasizes the integration of privacy risk management alongside security in the RMF process. In Revision 2, identifying privacy risks, implementing controls to mitigate these risks, and ensuring privacy considerations are addressed throughout the RMF process. This integration helps organizations manage both security and privacy risks comprehensively.

What is Supply Chain Risk Management (SCRM) in the context of the RMF?

SCRM involves identifying, assessing, and managing risks that arise from the supply chain, which can impact the security and privacy of information systems. Revision 2 of NIST SP 800-37 incorporates SCRM by encouraging organizations to consider supply chain risks during all RMF steps.

Is the NIST RMF applicable only to federal agencies?

While the NIST RMF was initially developed for federal agencies, its guidelines are widely applicable across various industries and sectors. Many private sector organizations, state and local governments, and international entities adopt the RMF to manage information security and privacy risks effectively.

How does continuous monitoring fit into the RMF?

Continuous monitoring is a critical component of the RMF, ensuring that security and privacy controls remain effective over time. This process involves ongoing assessments, real-time risk management, and regular reporting to detect and respond to changes in the threat landscape and organizational context.
