You are invited to attend the DETER Community Workshop on June 15 -16 in Arlington VA. This event will demonstrate the capabilities of the DETER Security Testbed and highlight the research of experimenters using the testbed. The DETER laboratory effort has developed a collaborative and vendor-neutral experimental environment for cyber-security research. The DETER effort includes

• DETER testbed: a shared testbed infrastructure based on the University of Utah's Emulab, that is specifically designed for medium-scale (e.g., 100 - 200 node) repeatable experiments, and especially for experiments that may involve "risky" code.

• DETER research community: a community of academic, industry, and government researchers working toward better defenses against malicious attacks on our networking infrastructure, especially critical infrastructure.

The nucleus of the DETER laboratory effort is formed of two research projects, DETER and EMIST, funded by the National Science Foundation (NSF) and DHS, along with a growing number of experimenters from academia, industry and government organizations.

Presentations at the workshop will demonstrate the current capabilities of the DETER testbed, methodologies and tools developed (under the EMIST grant and other research efforts) and highlight activities that have used the testbed.

Attendees are expected from a wide community of researchers, industry, and government program representatives. The workshop will include sessions on lessons learned from the first three years of testbed usage, national exercises, and future plans for the DETER Security Experimenters Workbench. The workshop will also provide an opportunity for the user community to exchange information on tools and methodologies. Finally, the workshop will include live demonstrations and posters from current testbed users.
