Hacker

Definition - What does Hacker mean?

A hacker utilizes alternative system access methods to sabotage computer systems and networks.

Hacking actions are differentiated as illegal and unacceptable (black/grey hat hacking), or legal and acceptable (white hat hacking).

Techopedia explains Hacker

Hacker is a term that refers to many different computing topics. However, in the mainstream, a hacker is any individual or group that circumvents security to access unauthorized data.

Most hackers are highly skilled computer programmers that locate security gaps and access secure systems via unique analytical skills. A great hacker is known to be able to "think outside the box."

Hacker types are delineated according to intent, as follows:

  • Black hat hackers break into computer systems illegally and cause harm by stealing or destroying data, i.e., a banking system to steal money for personal gain.
  • White hat hackers use their skills to help enterprises create robust computer systems.
  • Grey hat hackers perform illegal hacking activities to show off their skills, rather than to achieve personal gain.
