NIST is an agency under the U.S. Department of Commerce that develops and promotes measurement, standards, and technology. One of their primary responsibilities is the development of cyber security standards and guidelines, which help organizations improve their security posture by following the best practices and recommendations laid out by NIST.

Some important NIST publications related to cyber security are:

NIST Cybersecurity Framework

The NIST Cybersecurity Framework provides a structure for managing cyber risks and helps organizations understand, communicate, and manage their cyber risks. It outlines five core functions:

NIST Special Publication 800-53 (SP 800-53)

NIST SP 800-53 provides guidelines for selecting security and privacy controls for federal information systems as well as for systems that process federal information. This publication defines specific security and privacy controls that can be applied to address various risk factors and offers guidance on tailoring these controls for the unique needs of an organization.

NIST Special Publication 800-171 (SP 800-171)

NIST SP 800-171 addresses security requirements for protecting controlled unclassified information (CUI) in non-federal information systems and organizations. It is particularly relevant for entities that work with federal agencies, as they must meet these requirements in order to manage and safeguard CUI effectively.

NIST Risk Management Framework (RMF)

The NIST Risk Management Framework provides a structured process for organizations to manage security and privacy risks using NIST guidelines and standards. This framework consists of six steps:

By following NIST cyber security standards, organizations can reduce their vulnerability to cyber-attacks and enhance their overall security posture.
