What does Hacking mean?
Hacking generally refers to unauthorized intrusion into a computer or a network. The person engaged in hacking activities is known as a hacker. This hacker may alter system or security features to accomplish a goal that differs from the original purpose of the system.
Hacking can also refer to non-malicious activities, usually involving unusual or improvised alterations to equipment or processes
TYPES OF HACKERS
Hackers Are Classified into 3 Parts :
1. BLACK HAT HACKERS
A black hat is a person who compromises the security of a computer system without permission from an authorized party, typically with malicious intent. The term white hat is used for a person who is ethically opposed to the abuse of computer systems, but is frequently no less skilled. The term cracker was coined by Richard Stallman to provide an alternative to using the existing word hacker for this meaning.The somewhat similar activity of defeating copy prevention devices in software which may or may not be legal in a country’s laws is actually software cracking.
2. WHITE HAT HACKERS
A white hat hacker is a computer security specialist who breaks into protected systems and networks to test and asses their security. White hat hackers use their skills to improve security by exposing vulnerabilities before malicious hackers (known as black hat hackers) can detect and exploit them. Although the methods used are similar, if not identical, to those employed by malicious hackers, white hat hackers have permission to employ them against the organization that has hired them.
3. GRAY HAT HACKERS
A gray hat hacker (also spelled grey hat hacker) is someone who may violate ethical standards or principles, but without the malicious intent ascribed to black hat hackers. Gray hat hackers may engage in practices that seem less than completely above board, but are often operating for the common good. Gray hat hackers represent the middle ground between white hat hackers, who operate on behalf of those maintaining secure systems, and black hat hackers who act maliciously to exploit vulnerabilities in systems.
