Access Control List

An Access Control List (ACL) is a security feature used in computer networks and systems to specify who can access certain resources and what actions they can take. Think of it like a guest list at a party—only approved people can enter, and they may have specific permissions, such as reading files or making changes. ACLs help protect data by allowing administrators to control access based on user identity, device, or network, ensuring that only authorized individuals can perform certain operations, thereby enhancing security and managing resource use effectively.
