Nobody could say when it had been configured that way, and the access log showed 40 accounts had read files they should never have seen. <code>Get-Acl</code> would have surfaced the problem in seconds.</p> <h2>What is an ACL on Windows?</h2> <h3>What does ACL mean in systems security?</h3> <p><strong>An ACL (Access Control List) is the permission list attached to a file or folder on Windows — it defines who can read, write, modify or take full control of that resource.</strong> Each entry in the list is called an ACE (Access Control Entry) and holds the user or group, the permission type, and whether it was inherited from the parent folder or set directly.</p>
