Yep. Jack Bauer uses them all the time. Every movie, TV show, novel, and newspaper article talks about them. Apparently, they exist as some magical device that at one time both renders a “server” impenetrable and throws open secret files to terrorists. Depending on the character in our little drama, there seems to always hide some trick or pathway around this “firewall” thing, and the description usually relies on pseudo-technical jargon to explain it away.
My wife and I home school our children using excellent videos from Abeka, and it works out very well. They can travel with me when the opportunity arises, work from the dentist’s waiting room, or whatever. Except for the problem of how to let the kids get to the Internet safely. Well, there’s all kinds of thoughts out there on the subject. Everything from “Don’t” (absolutist) to the school of thought that says “They’re Going to See It Anyway” (defeatist).

There are two main classification schemes for data objects; the most well-known is used by the US Government for protected national information.It uses terms, now made somewhat clichÃ©d in popular media. The other generally used schema is for the private sector.
Once again, I have pestered the editors at the ordinarily refined Linux.com into publishing an article. I had a harder time getting this one right. I was stuck in a fiction writing mode–half of the sentences I wrote were in passive voice. Very frustrating–probably more so for the editors.
In any case, go check out the story–SmoothWall is an excellent choice for network border security.
There are a great many commercial network security scanners on the market. McAfee FoundStone, HfNetCheck, Retina, and probably scads of others. The problem with this is the word “commercial”. Commercial means “takes money”. Well, scanning with Nessus would be a good way to save money, right?
