What aspect of security does the Access Control (AC) family primarily address?

The Access Control (AC) family primarily focuses on managing user permissions and access to information systems and resources. This involves establishing policies and procedures that determine who is authorized to access specific data or systems and under what conditions. The goal of access control is to ensure that only legitimate users can interact with or retrieve sensitive information, thus minimizing the risk of unauthorized access or data breaches.

Access control mechanisms can include user authentication processes, role-based access controls, and access control lists. These measures are essential for safeguarding sensitive information within the Department of Defense and ensuring that personnel have the appropriate level of access necessary for their roles.

This answer highlights the foundational concepts of access control and its significance within a security framework. Other choices, while related to security, focus on different areas: data encryption pertains specifically to protecting data at rest or in transit, network security deals with the integrity of networking infrastructure, and incident response protocols are about how organizations react to security breaches or incidents. These areas, while important, do not fall under the direct management of user access and permissions, which is the core function of the Access Control family.
