ACL

Access Control List

In plain language

A list attached to a file, folder or network device that states who is allowed to use it.

The metaphor

Like the guest list at a venue door: if your name is not on it, you do not get in.

Going deeper

How it works

  • Each entry says who and what they may do, such as read or edit.
  • Files, folders and firewall rules all use lists like this.
  • Lists grow messy over time and need a review.
  • Giving access to groups instead of individuals keeps them short.

How WILDCARD handles it

Cloud covers permissions in your workspace, and Network covers the firewall rules on the network side.

In practice
  • A firm checks who can open the payroll folder.
  • An office tightens a firewall list to allow only one printer address.
  • A shop removes a former employee from a shared drive.

A question owners ask

How often should I review who has access?

At least twice a year, and any time someone leaves or changes roles.
