What type of control restricts information system access to authorized users?

Access Control (AC.L1-3.11)
Account Management (AM)
Awareness and Training (AT)
Identification and Authentication (IA)

The correct answer is: Access Control (AC.L1-3.11)

Access control is the foundational mechanism for ensuring that information system access is limited to authorized users. This type of control encompasses policies and procedures that govern who can access specific resources within an information system and under what circumstances. Access control involves the implementation of various measures, including user permissions, roles, and credentials, to manage access to data and system functionalities effectively. This includes not only determining who is permitted to access the system but also enforcing restrictions based on the principle of least privilege, ensuring users have the minimum necessary access to perform their job functions. While account management focuses on the creation, modification, and deletion of user accounts, and identification and authentication concentrate on verifying user identity and providing secure access, they are components of the broader access control framework. Awareness and training emphasize the importance of informing users about security practices but do not directly restrict access. Therefore, access control is the key mechanism that ensures security by restricting access to only those users who have been authorized, making it essential for an organization's overall cybersecurity strategy.
