What is the primary purpose of an access control list (ACL)?

The primary purpose of an access control list (ACL) is to restrict access to network resources based on user permissions. ACLs are a set of rules that define which users or system processes have access to specific resources and what operations they can perform on those resources. This is essential for enforcing security policies and ensuring that only authorized personnel can access sensitive data or critical systems.

ACLs operate through a series of permission settings that can be applied to users or groups, determining if they can view, modify, or execute certain files or services. By implementing ACLs, organizations can protect their network resources from unauthorized access or attacks, ensuring that sensitive information remains secure and reducing the risk of data breaches.

In contrast, organizing files within a network, monitoring user activity, and enhancing network speed do not align with the core function of an ACL, which specifically focuses on defining and managing access rights and permissions.
