Access Control Lists (ACLs) in Linux provide a flexible and granular way to secure files and directories beyond traditional Unix permissions. While standard permissions only allow setting access for owner, group, and others, ACLs enable administrators to assign specific permissions to individual users and groups simultaneously. This allows fine-grained control over access rights using commands like setfacl and getfacl to define read, write, and execute permissions for multiple entities. How ACLs Work ACLs extend the basic Unix permission model by maintaining additional permission entries for files and directories. Each ACL entry specifies a user or group and their ...
