Classifying hackers by the technology they deal with can be complicated. Because networking and computer technology is so vast, hackers often specialize in one or a few specific areas. There are basically three types of hackers: Coders, Admins, and script kiddies. This characterization is based upon overall competence and ability to compromise computer technology, networks, protocols, and systems.

1. Coders - They are programmers who have the ability to find unique vulnerabilities in existing software and to create working exploit codes. These hackers, as a whole, are not seeking publicity and are rarely part of front-page news stories. As a result, they are known only to the security community for the programs they write and the exploits they have uncovered.

2. Admins - They are far more common than Coders and may have experience with several operating systems, understand TCP/IP, and know how to exploit several vulnerabilities. They generally have less depth of knowledge but possibly greater breadth than Coders. This level of hacker would be part of a security team in a large organization. Some level of programming or scripting ability is required. For example, they should be able to port a tool form on flavor of Unix to another.

3. Script Kiddies - They are the lowest and most populated part of the hacker pyramid. Their name comes from the fact that members of this group generally rely on previously coded scripts and prepackaged hacking tools downloaded from the Internet to do their hacking. Script kiddies are usually individuals who are intrigued by the notion of gaining unauthorized access and are open to using untested pieces of code, especially while others (target networks and users) are at risk.
