ACLs and DACLs

In Active Directory:

  • ACL (Access Control List): an ordered list attached to each object that defines permissions (grant/deny/audit).

  • ACE (Access Control Entry): an individual entry in an ACL specifying a security principal (user/group), access type (allow/deny/audit), and rights (e.g., read, write)

  • DACL (Discretionary Access Control List): part of the security descriptor that uses ACEs to determine who is allowed or denied access

Together, ACLs, ACEs, and DACLs are essential for securing and managing object access in AD.

There are tons of ACLs you can configure. I'll show how to configure the most common ones.
