The cyber security research realm is plagued with the problem of collecting and using trace data from sources. Methods of anonymizing public data sets have been proven to leak large amounts of private network data. Yet access to private and public trace data is needed, this is the problem that NEMESIS seeks to solve.

NEMESIS is a virtual network system level solution to the problem where instead of bringing the data to the experiments one brings the experiments to the data. NEMESIS provides security and isolation that other approaches have not; allowing for filtering and anonymization of trace data as needed.

The solution came about from a desire and need to have a system level solution that leveraged and allowed for the usages of the best current technologies, while remaining highly extendible to future needs.
