Secure DHCP?

  • From: Nicholas Bastin

(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.
