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 for the testing 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
- Website Hacking − Hacking a website means taking unauthorized control of 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, Netstat, etc. with the intent to harm the network system and hamper its operation
- Email Hacking − It includes getting unauthorized access to 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
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
- 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
- Just for fun
- Show-off
- Steal important information
- Damaging the system
- Hampering privacy
- Money extortion
- System security testing
Types of hackers
none Hat Hackers
none Hat hackers are also known as Ethical Hackers. They never intent to harm
a system, rather they try to find out weaknesses in a computer or a network
system as a part of penetration testing and vulnerability assessments.
Ethical hacking is not illegal and it is one of the demanding jobs available in
the IT industry. There are numerous companies that hire ethical hackers for
penetration testing and vulnerability assessments.
Black Hat Hackers
Black Hat hackers, also known as crackers, are those who hack in order to gain
unauthorized access to a system and harm its operations or steal sensitive
information.
Black Hat hacking is always illegal because of its bad intent which includes
stealing corporate data, violating privacy, damaging the system, blocking
network communication, etc.
