If logging can't be enabled on the countermeasure servers, how about
routing all those machines through an internal proxy and then tracking
the connections that way?

We don't keep a history of individual file hashes/IP addresses in our
protection system because the computers in our protection system are
already pushed close to their limits. Any deep data collection (file
hashes, IP addresses, etc.) on our protection system would negatively
affect our protection effectiveness. Because of this problem, we
created a separate data collection system in order to collect more raw
data.

The data feed files from our data collection system contain raw data for
supply and demand (including IP address) on the respective networks.
The data collection system only collects supply and demand, it is not
connected or related to our protection system in any way, so there is no
spoof, decoy, or interdiction data associated with the data feed files
for each network.

Do you record the file hashes (for edonkey in particular) for every
swarm you interdict? Is that in the supply feed?
