                 be repaired quickly. In many cases, this type of computer hacking helps prevent identity theft
                 and other serious computer-related crimes.

                 Security is an important issue for all modern information systems. The process of protecting
                 computer resources such as networks, devices, programs, and data from unauthorised access,

                 malicious acts of theft or disruption. Unfortunately, the number of cyber crimes is on the rise
                 around the world. The various reasons for increased cyber crimes are:
