Which of the following were purposes in introducing overlays in SP 800-53r4?

• A. Replace outdated security baselines
• B. Allow pre-tailoring of security baselines for specific situations
• C. Reduce the requirement for ad hoc tailoring
• D. Allow the Authorizing Official to pre-approve system operation

Answer: (B)

The introduction of overlays in NIST SP 800-53 Revision 4 serves several purposes, with the primary goal of facilitating the security baseline tailoring process for specific circumstances, which aligns with the choice that was selected. Overlays provide a mechanism for organizations to adapt and refine standard security controls to fit the unique environmental, operational, or risk requirements of their specific systems or missions. This pre-tailoring capability helps ensure that security baselines are not only relevant but also effectively address particular threats and vulnerabilities that may be present in different contexts. By allowing for specific customizations, overlays enhance the effectiveness of security measures while still maintaining a foundational baseline that is consistent with broader federal risk management frameworks. This tailored approach ultimately supports better alignment between security practices and the risk profile of an organization, leading to more efficient and effective security implementations. It enables organizations to focus on controls that are critical for their specific operational needs while still adhering to established standards.
