Access Control List (ACL)

32.5k

An Access Control List or ACL is a set of permissions given to an individual or group, limiting their access to a system. These are mostly used in Unix-like operating systems to control file access.

For file systems, an access control list (ACL) provides an additional, more flexible authorization mechanism. Its purpose is to help with UNIX file permissions. ACL allows you to grant rights to any disc resource to any user or group.

ACLs are a type of access control list. They are used to control the permissions of users and groups. An ACL is a set of instructions that define which users or groups have access to a certain resource. Those instructions can be stored in three different formats: as an ACL, as an Extended ACL, or as a named local group policy object (GPO). The first two formats can be applied within Windows NT file systems and NTFS file system volumes only. The last one is more flexible and can also be applied to Active Directory objects like user and group accounts, domains, organizational units (OUs), and sites.

A network access control list (ACL) is a set of rules that either grant or refuse access to a computer system.

The primary goal of utilising an ACL is to secure your network. Without it, any traffic can enter or exit, leaving the area open to unwelcome and harmful traffic. You can use an ACL to improve security by denying specific routing modifications or controlling traffic flow.
