ACLs in Computing

Access Control Lists (ACLs) are tools used in computing to manage who can access resources, such as files or networks. Think of an ACL as a list of permissions that specifies which users or systems can perform certain actions, like reading, writing, or executing. For example, in a shared folder, an ACL can allow some people to view the contents while restricting others from making changes. This helps ensure security and proper use of information by controlling access according to permissions set by an administrator or resource owner.
