What Is Hacking ??

Hacking  has  been  a  part  of  computing  for  almost five  decades and  it  is  a  very  broad discipline, which covers a wide range of topics. The first known event of hacking had taken place in 1960 at MIT and at the same time,the term "Hacker" was originated.Hacking is the act of finding the possible entry points that exist in a computer system or a computer  network  and  finally  entering  into  them.  Hacking  is  usually  done  to  gain unauthorized  access to  a computer  system  or a computer  network,either  to  harm  the systems or to steal sensitive information available on the computer.

Hacking is usually legal as long as it is being done to find weaknesses in a computer or network system fortesting purpose. This sort of hacking is what we call Ethical Hacking.A computer expert who does the act of hacking is called a "Hacker". Hackers are those who seek knowledge, to understand how systems operate, how they are designed, and then attempt to play with these systems.

Types of Hacking

We can segregate hacking into different categories, based on what is being hacked. Hereis a set of examples:

Website Hacking: Hacking a website means taking unauthorized control over a web server and its associated software such as databases and other interfaces.

Network  Hacking: Hacking  a  network means  gathering  information  about  a network by using tools like Telnet, NS lookup, Ping, Tracert, Net stat, etc.with the intent to harm the network system and hamper its operation.

Email Hacking: It includes getting unauthorized access on an Email account and using it without taking the consent of its owner.

Ethical  Hacking: Ethical  hacking involves  finding weaknesses  in  a  computer  or network system for testing purpose and finally getting them fixed.

Password Hacking: This is the process of recovering secret passwords from data that has been stored in or transmitted by a computer system.

Computer Hacking: This is the process of stealing computer ID and password by applying hacking methods and getting unauthorized access to a computer system.Advantages of Hacking. Hacking is quite useful in the following scenarios:

To recover lost information,especially in case you lost your password.

To perform penetration testing to strengthen computer and network security.To put adequate preventative measures in place to prevent security breaches

To have a computer system that prevents malicious hackers from gaining access.


Disadvantages of Hacking

Hacking is quite dangerous if it is done with harmful intent.

It can cause:

Massive security breach.
Unauthorized system access on private information.
Privacy violation.
Hampering system operation.
Denial of service attacks
Malicious attack on the system. Purpose of Hacking. There  could  be  various  positive  and  negative  intentions  behind  performing  hacking activities.Here is a list of some probable reasons

why people indulge in hacking activities:

Just for fun
Show-off
Steal important information
Damaging the system
Hampering privacy
Money extortion
