Marc Solomon: Defense-in-Depth has Failed Us. Now What?
Wow, there's so much wrong with this article that I don't even know where to start... Defense in depth does not mean, as the author seems to think, to heap "disparate" "point products" onto one another in the hopes that one will probably catch an attack attempt. Defense in depth means to understand both the threat landscape and the environment you're trying to defend, tailor solutions to make an attacker's job as hard as possible, and find the right points to place meaningful alarms. (Which rarely anyone ever does, but that's a different topic.)
Oh, I do get that threat intelligence services are the current hot stuff in the security industry (and the author wants to help sell his own), but when a defender doesn't get the basics of IT security design, heaping another "point product" on top won't help a whole lot.
