Schneier’s Law Applied to Networking
A while ago I stumbled upon Schneier’s law (must-read):
Any person can invent a security system so clever that she or he can't think of how to break it.
I’m pretty sure there’s a networking equivalent:
Any person can create a clever network design that is so complex that she or he can't figure out how it will fail in production.
I know I’ve been there with my early OSPF network designs.
