For example, decide which tools could be used to help protect your hardware and data, to prevent theft of equipment and attacks by viruses and hackers, to detect viruses and unauthorized use, and to recover from natural disasters. Recovering from Disasters Once you complete your risk analysis and reduce your risks to an acceptable level, begin planning for emergencies. If something goes wrong that threatens your system's security, you need a contingency plan to fall back on. Your backup plan should enable you to respond to the crisis and recover from the disaster. This process is called disaster recovery.
Successful recovery is dependent on taking certain preventative measures.
Install emergency power supply systems and surge suppressors to protect against interruptions in your power supply. Make emergency startup disks for each PC in your system so you can boot from clean system disks after virus attacks. Your contingency plan should indicate what actions to take when an accident occurs and who is responsible for taking those actions. If you already have someone on your staff who is competent in restoring lost data, removing viruses, backing up systems, etc. Make sure you have a backup plan in place for when that person goes on vacation.
