Some organisations actually employ computer hackers as part of their technical support staff.
                  These individuals use their skills to find flaws in the company’s security system so that they can
                  be repaired quickly. In many cases, this type of computer hacking helps prevent identity theft
                  and other serious computer-related crimes.

                  Cracking
                  The  process  of  stealing  personal  information,  changing  financial  data,  and  breaking  security
                  systems to gain unauthorised access to computer systems  is called cracking. The people who
                  are involved in the process of cracking are called crackers.
                  Software cracking is considered illegal and cracked software is often called pirated software.


                   i +  CYBERSECURITY

                  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,
                  damage, or attack is called cybersecurity.

                  Confidential data and privacy must be safeguarded, and the system must be protected against
                  malicious acts of theft or disruption. Unfortunately, the number of cybrcrimes is on the rise
                  around the world. The various reasons for increased cybrcrimes are:

                  •  Increasing use of Internet                      •  Multi-pronged attacks
                  •  Lack of awareness                               •  Existing loopholes in software

                  •  Untrained Internet users
