Hi all!Just wondering, is there a way to "prevent" a rogue DCHP server from playing havoc with a network? I have been digging into "dhcp security" but I haven't really found anything that makes it possible to auth. a DHCP server, so that the clients don't fall for a rogue one.
I wrote a paper on this (and put the slides for a presentation I did on it online). At the time (and still, apart from what I've stuck online), there doesn't seem to be any definitive guide to why DHCP is insecure and what one might do to improve it. It's not totally exhaustive, but I think it's reasonable:
