> What is your home address and phone number?

Neither of those are security systems. That's like asking for their password and claiming you've proven security through obscurity.

The idea behind dismissing obscurity is that if everything but private tokens were exposed, your system should still remain secure.

If you think that your address and phone number are secret information, consider how easy it would be to find yours from the information in your HN profile. I'm pretty sure I found your entry on whitepages within a few minutes and I'm barely motivated to find it.

I thought you were asking a rhetorical question to show that obfuscation is a valid security measure that we all use. What was your intention?

The correct question should be: "what firewall and IDS do you use?"
