Hackers in the field of computer security is concerned with breech of security mechanisms and finding their weaknesses.

Hackers : The Less Known World

 

Depending on the motivation and loyalty to the law, a distinction is made between the hackers – White Hat Hackers, Black Hat Hackers, Blue or Gray Hat Hackers and the Black Hat hackers are synonymous to as crackers. Following the introduction of laws on cybercrime, white hat, gray hat and black hat hackers are distinguished from each other, depending on the legality of their activities. This classification is based on characterizes old Western films, which “Cowboys” (white) because of their hat color as “good”, “neutral” (gray) or “bad” (Black) – typically like a villain in movies of ’70s.Previously we published how Methodology hackers use for an intrusion to a network and about cybercrime.

White hat : Hackers using their knowledge both within the law and within the hacker ethics, for example, by a professional for network penetration as test.

Virus : A computer virus is a computer program or script which has the special property of reproducing itself, once it is executed.

Through user interaction, which connects an infected removable media to another system, the virus code also reaches for execution, by which other systems are infected by the virus. Besides the secret spread of the virus, the malicious function make changes to the system can not be controlled. In this way it is possible to compromise many computers in a corporate network or even semi-automatically from the Internet server.
Worm : Unlike the virus, the computer worm is a system installed utility that is used in order to copy to another system. This could be for example a particular e-mail program that remotely controls the worm, to be distributed to all recipients listed there. Depending on the nature of the utility itself, the worm code on the newly infected system. Therefore, this method is very efficient. On systems that do not have the necessary utility to the worm can not reproduce.
