Re: Locking down Ports and DHCP (Tyler Robinson)

If you are running Cisco as the switching platform, I have a configuration builder on my blog http://www.melcara.com.  
The posting is called "Secure Switch Config 0.01".  The config builder show how to enable Dynamic ARP Inspection (DAI), 
DHCP Snooping and Port Security.  The config builder also shows how to harden then control plane of the switch.  If you 
don't have Cisco switches, the concepts shown should also be somewhat applied to any other vender if the vender 
supports the features previously mentioned.  Also you  might want to consider something like 802.1x, which uses RADIUS 
to authenticate a user to the switch port and can quarantine the user if authentication fails.  Sophos 
(www.sophos.com<http://www.sophos.com>) also have a good NAC product and the Cisco NAC is good, but very expensive.
