Some responses to Carolyn Meinel's SciAm Article.. In the October 1998 special report on computer security, the term "hacker" was used incorrectly. You stated that hackers are malicious computer security burglars, which is not the correct mean- ing of "hacker" at all. The correct term for such a person is "cracker." Hackers are the expert programmers who engi- neered the Internet, wrote C and UNIX and made the World Wide Web work. Please show more respect for hackers in the future. Further information about this distinction can be found at the Hacker Anti-Defamation League's site at http://members.xoom.com/jcenters/ on the World Wide Web. JOSH CENTERS via e-mail Editors' note: We agree that there is indeed a differ- ence between "hacker" and "cracker," but the mainstream media has used "hacker" to encompass both. We did, however, try to draw a distinction by using the term "white-hat hacker." Part of the problem with "cracker" is that the word has been used disparagingly in the past to refer to a poor, white per- son from the South. As a computer security professional with many years' experience in both public and private industry, I was extremely disturbed to see that you published an article by Carolyn P. Meinel in your October issue ["How Hackers Break In ... and How They Are Caught"]. Meinel has absolutely no credibility in the computer security community. She does not have the tech- nical awareness to be considered know- ledgeable, nor is she in any stretch of the imagination considered an expert in the field. Her article probably gave CEOs a fairly good sense of how insecure their networks might be, but I shudder to think that companies looking to jump on the computer security bandwagon will now be using her article as a tech- nical reference.
