The .dll, or .ida files can be dropped at an edge router as well if you use
a Cisco router. You will need to use : 2600 3640 7200 IOS 12.1(5)T and the
7500 IOS 12.1(6)E. Check www.cisco.com for more info or here:
http://iponeverything.net/CodeRed.html . The beauty of this solution is that
it can be used to block Code Red infections today and can be easily modified
with new signatures in the future using the HTTP sub-port classification
mechanism in IOS.
