What do you know about hacking? Do you thinkgetting into someones facebook account or google account is called hacking? No.
In computer networking, Hacking is any technicaleffort to manipulate behaviour of network connections and connected systems.
Hacking is historically referred to constructive,clever technical work that was not necessarily related to computer systems.
So when did hacking originate? MIT engineers in 1960s carried out some harmlesstechnical experiments and fun learning activities.
These were so called hacks.
Before the internet, several hackers in USexperimented with methods to modify telephones for making 'FREE' long distance calls overthe phone network illegally.
As computer networking and internet explodedin popularity, data networks became the most common target of hackers.
Malicious attacks on computer networks areofficially known as cracking, while hacking truly applies only to activites having goodintentions.
However, Most non technical people fail tomake this distinction.
Hacking on computer networks is often donethrough scripts or other network programming.
These programs generally manipulate data passingthrough a network connection in ways designed to obtain more information about how the targetsystem works.
Many such pre-packaged scripts are posted on the Internet for anyone, typicallyentry-level hackers, to use.
More advanced hackers may study and modify these scriptsto develop new methods.
A few highly skilled hackers work for commercial firms with thejob to protect that company's software and data from outside hacking.
Cracking techniques on networks include creatingworms, initiating denial of service (DoS) attacks, or establishing unauthorized remoteaccess connections to a device.
I will talk more about viruses, worms, dosattacks, etc on this channel.
