Which aspect is NOT covered by SP 800-53?

SP 800-53, developed by NIST (National Institute of Standards and Technology), focuses mainly on security and privacy controls for federal information systems and organizations. The primary aim of this framework is to provide a catalog of security controls that address a wide range of security and compliance needs, including risk management, assessment, and security controls in areas such as incident response, data integrity, and access control.

The aspect of Public Relations Management is not covered by SP 800-53, as it does not fall within the framework's focus on technical security controls and risk management methodologies. Public relations, typically concerned with managing an organization’s communication with external stakeholders and the public, does not align with the core objectives of SP 800-53, which are to define and guide the implementation of security and privacy controls within information systems.

In contrast, the other areas mentioned—security and privacy controls, incident response plans, and data integrity protection—are all integral components of the SP 800-53 framework, highlighting its comprehensive approach to managing security and privacy risks in information systems.
