For example, President Clinton proposed that we develop an information security "cyber-corps" of recent college grads to fight DDoS and other cybercrimes. Assume a service should be turned off, unless it is absolutely required.

Contact your operating system vendor to find out if there are additional kernel level services that are not in the system documentation, and, if so, how to disable them.
Peer2Peer or DNS Peer2Peer Command and Control distributes functionality within the botnet itself, not relying on a single system for administration duties. Compare the available tools from security tool vendors. The bots can point to multiple servers for redundancy and improved survivability. It should be noted, however, that in all likelihood a more intrusive government role is inevitable if uncontrollable attacks continue.
Against Smurf To determine if you are an attack platform: Despite all the warnings and the fines, backhoe operators end up digging up fiberoptic cables and disrupting networks.
