This FAQ will concentrate wholly upon computer related security issues.
The discussions posted range from the likes of "What's such-and-such system like?" and "What is the best software I can use to do so-and-so" to "How shall we fix this particular bug?", although there is often a low signal to noise ratio in the newsgroup (a problem which this FAQ hopes to address).
The most common flamewars start when an apparent security novice posts a message saying "Can someone explain how the such-and-such security hole works?" and s/he is immediately leapt upon by a group of self appointed people who crucify the person for asking such an "unsound" question in a public place, and flame him/her for "obviously" being a cr/hacker.
Please remember that grilling someone over a high flame on the grounds that they are "a possible cr/hacker" does nothing more than generate a lot of bad feeling. If computer security issues are to be dealt with in an effective manner, the campaigns must be brought (to a large extent) into the open.
Implementing computer security can turn ordinary people into rampaging paranoiacs, unable to act reasonably when faced with a new situation. Such people take an adversarial attitude to the rest of the human race, and if someone like this is in charge of a system, users will rapidly find their machine becoming more restrictive and less friendly (fun?) to use.
This can lead to embarrasing situations, eg: (in one university) banning a head of department from the college mainframe for using a network utility that he wasn't expected to. This apparently required a lot of explaining to an unsympathetic committee to get sorted out.
A more sensible approach is to secure a system according to its needs, and if its needs are great enough, isolate it completely. Please, don't lose your sanity to the cause of computer security; it's not worth it.
