Working with Linux File Access Control Lists (FACLs)

In this lab, we'll review what file access lists (FACLs) are used for. We'll set up a FACL to restrict access to a single file. We'll implement one rule to permit access for a single user, and then we'll edit permissions to remove access for all other users.
