I agree heavily with you Joe. Security in DEPTH means multiple layers, and obscurity certainly does add one more dimension. Thank you for the well written response to clear up the misunderstandings going on.

Half the responses are slamming security that is dependent exclusively or heavily on obscurity. Was that really what the article proposed? Show me where. It's been a while since high school English classes so I will be the first to admit I can misread things at times. From what I can tell, the article proposes that adding obscurity to an already well secured system can add benefits. While I think the analogy used in the article is pretty weak, the idea is not. Quite a few security researchers have done this but feel free to try it for yourself. Setup some server application that is a common target for attacks (just so you'll get some quick responses) using standard secure configuration and setup another one in exactly the same secure way but listening on some completely off-the-wall port and non-default protocol. Track how many attempts you get on each. Again, security that is heavily or solely dependent on obscurity is bad - I don't think there'll be a lot of contention there. However, Mr. Miessler is proposing that if you already have reasonable security measures in place, obscurity can provided an added layer. This actually does help in many situations. Is it a security cure-all? Well, is anything?
