Necip,

I believe we're already feeding Aaron's team gigs of data feeds from our Data Collection system daily.

Thanks,
Ben

Aaron and all,
 
I interpret "90% overlap" to mean that the Data Collection system sees 90% of the interdictions (decoys files?) served by the Protection System. It misses the other 10%. If so, this is a very good number.
 
On a related note, I really do not know what type of data is being captured by the Data Collection System. What triggered my interest on this topic was the desire to enable ourselves to gain visibility into countermeasures at the individual infringer level (e.g., IP and preferably the user hash on eDonkey). I need to learn more about the type of data being captured and stored by the DC system. Can I see a quick snapshot?
 
Best wishes,
 
Necip

Thanks Ben. Necip, 90% overlap sounds like it would be good enough. Shall we proceed as is?

Aaron,

 

Too funny. I just saw the e-mail from Andrew. Here's what we had to say.

Andrew,

 

The fundamental problem is that we can't link the Protection System to the Data Collection system completely. We extrapolated from a sample of several of our nodes on the network and found a high percentage of overlap between the Protection and Data Collection systems -- in the 90%+ range. We ran these tests since the Tuesday following our phone call through this morning to extend the time frame to smooth out any inter-day or intra-day noise. This was a huge effort which required several of our development staff to run manual queries on each node at different times of the day, affecting each computer's Protection performance.

 

Thanks,

Ben Grodsky

Hi Ben,

 

Have you been able to run any tests to estimate how much overlap there is between what the countermeasure machines see? When can we expect this data?

 

 

Thanks,

Andrew
