Understanding Access Control Lists
An Access Control List (ACL) is a security record that decides who can enter a system, file, or network. Think of it as a guest list for digital resources. Each rule in the list outlines which users or devices can read, edit, or block data. This way, sensitive information stays protected while approved users keep working without interruption.
ACLs appear in many places. On a computer, they can manage file permissions. In a business network, they can filter traffic through routers and firewalls. Within software, they can assign user roles that match job needs. No matter the setup, an access rules list helps reduce risk and keep systems organized.
