Which NIST document addresses security and privacy controls for federal information systems but is not specifically focused on Zero Trust Architecture?

The choice referencing NIST 800-53 is correct because this document provides a comprehensive set of security and privacy controls tailored for federal information systems. It is designed to help organizations meet the requirements of the Federal Information Security Modernization Act (FISMA). NIST 800-53 focuses on a broad range of security controls that address various threats, vulnerabilities, and risks without being specifically tied to any architecture framework such as Zero Trust Architecture.

In contrast, other choices indicate documents that serve different purposes. NIST 800-61 is focused on incident handling, providing guidelines for effectively responding to and managing security incidents but does not address the broader control framework that NIST 800-53 covers. NIST 800-84 details the testing and evaluation of security controls but is not a core document for establishing baseline controls like NIST 800-53. NIST 800-207 explicitly discusses Zero Trust Architecture, making it unsuitable for fulfilling the requirement of focusing on a comprehensive set of controls without the Zero Trust framework context. Thus, NIST 800-53 is the document that meets the criteria of addressing security and privacy controls for federal information systems without a specific focus on Zero Trust Architecture.
