How do you prevent your software being vulnerable to IP address spoofing? Authentication? Certificates? VPN? Nah, just check the MAC address field of every packet. Nobody ever spoofed a MAC address before, that's just impossible. I thought that in binary there were only ones and zeros, but I guess nobody told me about the special tamper-resistant ones and zeros that MAC address fields are made of.

Oh, once you've done that, don't forget to tell the marketing people to put it in a brochure as an "innovation" for everyone to see.

I should post more of the crap the idiots I work "with" (quotes, because I am only here in body not mind) say. Especially when it comes to network stuff.
