Secure your Unix system and explore methods for controlling file system and command execution access. During this course you will start by learning how to use chmod and changemode commands to set standard Unix file system permissions. Next, learn how to use an ACL (Access Control List) to assign user access and specify allowed operations. Understand Unix special permission bits to control read, write, and execute permissions for file users. Observe how to distinguish access privilege levels for Unix files, including the root user. Other topics on this course include the following: Configure Sudo to enable standard users to run privileged commands; Create a firewall to block unwanted network access; Configure and test OpenBSD PF Firewall rules.
