The computer network has become the mainstay of a workplace, whether it is an office, small business or a large corporate. It stores all kinds of data, confidential and general. It lends itself to various activities. It is integrated between different departments. People share information on it and use information stored in it. There is a lot of software stored on the mainframe that can be used by everyone in the network. Businesses are run via the computer system. If this system shuts down, it is akin to the company closing down till it is fixed again. If it crashes, millions of dollars will be wasted while the system is put back on track again.

What could cause a system to shut down or a crash?
The most common cause for a system shut down is when the system perceives a threat.

If it is unable to defend the network against the threat, inbuilt defense systems automatically take over and shut the system down, till measures can be taken to rectify the threat.
