Computer security is information security as applied to computers and networks.
The field covers all the processes and mechanisms by which computer-based equipment, information and 
services are protected from unintended or
 unauthorized access, change or destruction.
 This included not only protection from unauthorized activities or untrustworthy individuals, but also from unplanned events and natural disasters.
