    Learn how to lock down your Linux system from unwanted access locally and across the network with eight helpful system controls.

    Security is a perennial topic of interest for sysadmins. And securing new systems always presents a challenge because there really are no set standards for doing so. I'm pulling this article's list of security measures and controls from a variety of sources, including personal experience, DISA STIGs, and recommendations from other system administrators and security folks. While these security measures are good, they're only a first step toward better system security. These eight system controls are in no particular order of importance.
