A breakdown of security control families in NIST SP 800-53

The NIST SP 800-53 framework provides a comprehensive set of controls that organizations can use to protect their information systems and ensure compliance with US federal regulations. These controls are organized into 20 security control families, which are:

NIST SP 800-53 control families include specific controls for implementing and maintaining security measures. For example, the access control family includes controls such as account management, access enforcement, and least privilege. The audit and accountability family includes controls for audit generation, audit review, and audit reduction.

The selection of security controls is guided by the impact levels defined by the Federal Information Processing Standards (FIPS) Publication 199. The impact levels (low, moderate, and high) reflect the potential impact that a breach or compromise of the information would have on the organization and determine the minimum set of security controls that must be implemented.

To align with NIST SP 800-53, organizations can select the appropriate security controls from the relevant control families and implement them. 6clicks can then streamline the compliance process by providing a centralized platform for managing compliance efforts and automating control assessments.

It is essential to designate a dedicated team to assess, implement, and monitor the selected controls in NIST SP 800-53. By assigning specific roles and responsibilities, organizations can avoid duplication of efforts and allow for better coordination and accountability throughout the compliance process.

Continuous monitoring is also a key aspect of NIST SP 800-53 compliance. It is important to have mechanisms in place as well as people operating them to consistently track and evaluate compliance with the selected controls. This enables organizations to identify and address any potential non-compliance issues promptly.

Understand your existing policies and operation

Each organization has its own unique set of policies, procedures, and operational needs, which must be taken into consideration when implementing the security controls of NIST SP 800-53.

By understanding your existing policies and operations, you can accurately assess your organization's privacy and security needs. This allows you to identify the appropriate controls that address the specific risks and threats your organization faces, ensuring that you implement the most appropriate and effective measures to protect your systems and data.

Take a common approach to implementation where possible

Opting for a common approach to NIST SP 800-53 implementation can save valuable resources and time for organizations. Luckily, several controls within the framework can be implemented centrally and then embedded in different systems or programs.

For example, control guidance on user account access can be utilized as a common policy across multiple systems or programs. This not only saves time in developing individual policies for each system but also ensures consistency and reduces the risk of errors or gaps in security measures.

By adopting a common approach to implementation where possible, organizations can allocate resources more effectively and optimize their compliance efforts.

Reference the control catalog

The NIST SP 800-53 control catalog serves as a comprehensive resource that provides valuable information and guidance for organizations to effectively implement and adapt controls based on their specific requirements or risk profiles.

One of the key benefits of using the control catalog is that it helps organizations identify the interdependencies between controls. Some controls may rely on or be connected to others, and understanding these relationships is crucial for a successful and systematic implementation.

Moreover, the control catalog provides additional information on control enhancements and control baselines, allowing organizations to choose the most appropriate controls for their specific security needs and risk appetite.

Record evidence of implementation

Efficient evidence collection is another critical factor to consider. Organizations must be able to provide auditors and stakeholders with the necessary evidence to demonstrate their compliance with NIST SP 800-53 and provide assurance of their security posture.

Records of how each control is implemented, managed, and monitored, as well as any changes made over time must be properly documented and maintained. This documentation serves as proof that the necessary security controls have been implemented and are functioning effectively.

Proper record-keeping also allows organizations to track and manage their progress in implementing security controls and ensures that critical information is accessible for future reference, including during incident response or when conducting risk assessments.
