More Physical Security Measures

Treat the physical security of your servers with as much seriousness as you do network security. Using the checklist below, you should be able to make your physical location a bit more secure; at a minimum, you'll make things a lot more difficult for anyone looking to cause damage.

  • Disable servers' floppy and CD-ROM drives if you don't need them and if your OS permits this action.
  • In your BIOS, disable booting from floppy disks or from CD-ROM. Also, set a BIOS password so that others can't change this setting.
  • Don't leave documentation of your systems, network architecture, or passwords near the servers. Store documentation in a secured cabinet that requires a key for access, or better yet, store it on the network only and use access control to protect it.
  • Protect network devices such as routers, hubs, and switches. A switch in an unlocked closet could be used as an access point to cause network downtime.
