To prevent computer theft, we should secure the environment. Prevention measures help you to stop theft or burglars from stealing your computer.

Flood, hurricane, tornado, fire can also cause a physical damage to a computer system. The power outage has a great impact in business. Hackers can take an advantage of this to get in someone's computer system to steal database, records.
Besides all above reasons of hardware security concern, the unauthorized access is brought to attention.
