While the traditional method (ugo/rwx) of permissions is generally useful for providing access to files and directories, sometimes we need a little more. Access Control Lists (ACLs) give us finer-grained control of Linux filesystem permissions. In this hands-on lab, we will create and use file access control lists on RHEL 8.
Successfully complete this lab by achieving the following learning objectives:
- Configure a Shared Directory for Collaboration
- Configure a directory for collaboration using ACL’s.
- Grant Users additional permissions to the directory.
- Test user’s access by creating files.
- Remove a Current User’s Permissions to the Shared Directory
- Backup the directory Access Control List permissions.
- Remove a user’s access the directory.
- Restore the directory permissions.
