Computer Security

And another part of network security includes computer security. Computer Security means protecting your computer system from unwanted damages due to network. One of the major reasons for such damages is computer viruses or spyware on the computer. Viruses wipe off all the data or information from the hard disk. And sometime it may cause hardware problems too. The network must be protected from such type of software damages.  The people behind this software damages are generally known as hackers.  As a computer network is a part of it so the computer security from hackers is also a part of network security. The need for computer security from hackers are as follows:- 

  • It needs proper protection from the worms.
  • It should be protected from replicating and capturing viruses from infected files.
