Disaster Planning: Preparation for Recovery After an Attack

Disaster planning should be a key part of your security strategy. The old saying “Hope for the best, and prepare for the worst” certainly applies to PC or network security. Murphy’s law predicts that if you don’t have a way to recover from a network or security disaster, you’ll need one. If you’re prepared, you can recover quickly and may even be able to learn something useful from the experience. Here are some suggestions to help you prepare for the worst:

  • Make permanent, archived “baseline” backups of exposed computers before they’re connected to the Internet and anytime system software is changed.

  • Make frequent backups once online.

  • Prepare written, thorough, and tested computer restore procedures.

  • Write and maintain documentation of your software and network configuration.

  • Prepare an incident plan.
