(I felt this message had enough operational relevance to post on this list. If
any feels otherwise, please let me know.)
After having experienced a rather malicious attack on our corporate network by
someone running a rogue DHCP server, I'm wondering if there's any way to
prevent this from happening again? The perpetrator basically managed to
renumber most of an entire subnet (into an entirely different IP block) of our
network, causing a major denail of service. I've read the RFC's and checked
all the network reference books I can find, and none of them indicate any way
to prevent this from happening again. Am I missing something here, or is it
time to start writing RFC's? Thanks in advance.
