Center for Internet Security (CIS) Framework versus NIST SP 800-171

The Center for Internet Security (CIS) Framework is an internationally recognized, non-profit organization dedicated to improving the security of networks and systems around the world. The CIS Framework is a set of best practices and security standards designed to help organizations protect their systems from cyber threats. The Framework is composed of three components: the CIS Controls, the CIS Benchmarks, and the CIS Hardened Images. The CIS Controls provide a set of 20 security controls that are recommended to be implemented in order to achieve a secure environment. The CIS Benchmarks provide detailed, step-by-step instructions on how to properly configure and secure network and system components. Lastly, the CIS Hardened Images provide pre-configured, hardened operating system images that can be used to quickly and securely deploy systems. All three components of the CIS Framework are regularly updated to ensure that organizations are using the most up-to-date security measures.

The National Institute of Standards and Technology (NIST) Special Publication (SP) 800-171, “Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations”, provides guidance for protecting Controlled Unclassified Information (CUI) in nonfederal systems and organizations. The publication outlines the security requirements for protecting CUI in nonfederal systems and organizations, and provides guidance for assessing and mitigating the risks associated with CUI. The publication also provides guidance for organizations to develop and implement a security program to protect CUI from unauthorized access, use, disclosure, disruption, modification, or destruction. The publication is intended to provide guidance to nonfederal organizations on how to protect CUI in their systems and organizations.

1. Both frameworks are developed and maintained by the US government.

2. Both frameworks focus on the protection of sensitive information, including data security and privacy.

3. Both frameworks use a risk-based approach to prioritize security objectives.

4. Both frameworks provide guidance on developing security policies, procedures, and technical controls.

5. Both frameworks provide guidance on implementation of controls and testing of the implemented controls.

1. The CIS Framework is a set of security best practices for organizations of all sizes, while NIST SP 800-171 is a set of security requirements for organizations that handle controlled unclassified information (CUI).

2. The CIS Framework is a voluntary framework, while NIST SP 800-171 is a mandatory requirement for organizations that handle CUI.

3. The CIS Framework is focused on system hardening and security best practices, while NIST SP 800-171 is focused on protecting sensitive data.

4. The CIS Framework is a broad set of security best practices, while NIST SP 800-171 is a specific set of security requirements.

5. The CIS Framework is available to all organizations, while NIST SP 800-171 is only applicable to organizations that handle CUI.
