I accept the first bet and please send the $100 to ST Vincent's Community Services. I do believe that the bet was "1 instructor" - here are a couple quotes and a couple courses that dispell your assumptions regards to SANS. Don't bother sending me the money - just the charity above. Security 309 - A Framework for Information Security - Day 1 (see course notes) (Schneier): Relying on security through obscurity (proprietary interfaces and older equipment) is always a chancy proposition. (Shpantzer): Security by obscurity MAY work for opportunistic threats but determined threats targeting a particular network love this model. Security/ Writing Secure Web Applications - SANS London 2006 "Developers who once could rely on application obscurity are now targeted by criminals who use their programming errors to make millions of dollars in illicit gains and bring shame and ridicule to the victim organizations."

This idea that your logs are not full of junk as you have obscurity? Where did this come from? Please?
Are you serious? How about because the only people touching your daemon will be those with private information? Hence, less noise. I hate to bust out with this, Craig, but you seem to have some major gaps in your understanding of the concepts being discussed here. You have SANS certifications. Find me a SANS instructor that disagrees with my article. I'll bet you $100 that you can't. I'll also bet that I can find 3 (Mike Poor, Eric Cole, Ed Skoudis) that agree with it. Plus, I've already run the issue by Richard Bejtlich (a speaker at SANS and the author of Tao Of Network Security Monitoring). He promotes the running of SSH on a non-standard port, and agrees with my position. In short, you're out in left field somewhere. You're obviously a bright guy, though, so I'm not quite sure why this isn't clicking for you. But since it isn't I'm not going to keep debating you about it.
