If you are in charge of securing your school's computer lab, what steps would
                                    you take to protect the computers from hackers, and how would you ensure
                                    that your classmates' data stays safe?


                      CYBER THREATS

                  Cyber threat is a criminal activity in which computers are used to damage data, steal data, or
                  disrupt the digital life of a person. Most cyber threats are carried out in order to gain personal
                  profit. Some people break security only to check their skills.
                  Types of Cyber Threats

                  There are various types of cyber threats. Some of them are as follows:
                  Data Diddling

                  This refers to the process of changing the data going into or out of a computer. For example, a
                  student breaks into his/her university’s grade recording system and changes the grades he/she
                  earned in the last semester or class, thus raising his/her grade point average.
                  Phreaking

                  This crime is  committed against telephone companies by using computers with the goal of
                  making free long-distance calls, impersonating directory assistance or other operator services,
                  diverting calls to numbers of the perpetrator’s choice, or tapping phone lines.
                  Cloning

                  This refers to a fraud in which scanners are used to steal the electronic serial numbers of cellular
                  phones, which may be used for billing purposes and making broadcast calls. With stolen serial
                  numbers, clones can be made to make free calls that are billed to the owner of the original cell phone.
                  Carding

                  This refers to the process of stealing credit card numbers online, to be resold or used to charge
                  merchandise against the victim’s account.
                  Hacking

                  Hacking is when someone accesses someone else's computer or account without permission.
                  They might steal information, change things, or cause other problems. People who engage in
                  computer hacking activities are often called hackers.
                  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.
