This hour, you've learned to consider the physical environment as an integral part of a holistic approach to Linux security. The basic steps to be taken are

  • Lock away all systems in isolation when possible.

  • Prevent power cycle issues by disabling reset and power buttons, securing the power cable, and installing battery backups.

  • Lock floppy and CD-ROM drives or remove them altogether if they aren't needed.

  • Install a cable lock of some kind to prevent your entire box from being stolen.

  • Lock your case as well.

  • Keep an active list of those individuals who have physical access to the machine in question.

  • Be aware and be vigilant!
