Computer Hacking

Unlike most computer crime / misuse areas which are clear cut in terms of actions and legalities (e.g. softwarepiracy), computer hacking is more difficult to define. Computer hacking always involves some degree of infringement on the privacy of others or damage to computer-based property such as files, web pages or software. The impact of computer hacking varies from simply being simply invasive and annoying to illegal. There is an aura of mystery that surrounds hacking,and a prestige that accompanies being part of a relatively "elite" group of individuals who possess technological savvy and are willing to take the risks required to become a true "hacker". An interesting alternative view of how hackers positively impact areas such as software development and hacker ideology is presented in Technology and Pleasure: Considering Hacking Constructive.
Even attempting to define the term "hacker" is difficult. Perhaps the premiere WWW resource in introducing individuals to hacking is the The New Hacker's Dictionary (http://www.logophilia.com/jargon/jargon_toc.html), a resource which encompasses everything from hacker slang, jargon, hacker folklore, writing style and speech to general appearance, dress, education and personality characteristics. According to TheNew Hacker's Dictionary, a hacker can be defined as:
  1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary.
  2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming.
  3. A person capable of appreciating hack value.
  4. A person who is good at programming quickly.
  5. An expert at a particular program, or one who frequently does work using it or on it.
  6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example.
  7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations.
  8. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence 'password hacker', 'network hacker'. The correct term for this sense is cracker.
Even within hacker society, the definitions range from societally very positive (dare I say characteristic of gifted and talented individuals) to criminal. In his book, "Fighting Computer Crime: A New Framework for Protecting Information" (1998), Donn B. Parker lists two basic principles hacker live by:
  1. The belief that information sharing is a powerful good and that it is the ethical duty of hackers to share their expertise by writing free software and facilitating access to information and to computing resources whenever possible.
  2. The belief that system cracking for fun and exploitation is ethically OK as long as the cracker commits no theft, vandalism or breach of confidentiality.
Parker differentiates between benign and malicious hackers based on whether damage is performed, though in reality all hacking involves intrusion and a disregard for the efforts, works and property of others.

Ways to Minimize Potential for Hacking

There are a number of ways for schools to minimize potential for hacking.
  1. Schools need to clearly establish acceptable use policies and delineate appropriate and inappropriate actions to both students and staff.
  2. Students and staff need to instructed regarding hacking, the mentality associated with it, the consequences of various hacking actions and possible consequences of interacting and forming online relationships with anonymous individuals who claim to be proficient in invading others' privacy.
  3. The use of filters may be considered in reducing access to unauthorized software serial numbers and hacking-related materials, newsgroups, chatrooms and hacking organizations.
  4. Teachers need to be aware of student activities in the computer labs and pay special attention to things they hear in terms of hacking behavior.
