ACL’s

What is ACL’s?

Access Control Lists (ACLs) are fundamental security mechanisms used to control access to resources in computer systems and networks. An ACL is essentially a list of permissions attached to an object (like a file, directory, or network port), specifying which users or system processes are granted access to the object and what operations they are allowed to perform (e.g., read, write, execute). ACLs provide a more granular level of access control than simple permission schemes, enabling administrators to define precise rules for resource access.
