GRAFENWOEHR, Germany - Airmen from the 102nd  Network Warfare Squadron of the Rhode Island Air National Guard are learning to  protect computer operating systems from improper use, hacking and other  suspicious activity as part of Combined Endeavor 2010. 
Combined Endeavor, hosted here from Sept. 3-16, is the  largest military communications exercise of its kind in the world, which  enables participating nations to test the interoperability of their  communications systems and networks in order to support their nation's  respective security priorities during crisis.
FBI Director Robert S. Mueller III recently told the  Washington Post that terrorist organizations have identified cyberspace as  "a means to damage both our economy and our psyche -- and countless  extremists have taken this to heart." 
The 102nd NWS supports Combined Endeavor by ensuring no  inappropriate or malicious activity on the network interrupts the test  schedule. Each of the 40-partner nations participating in the exercise may have  differing ideas of minimum network security criteria.
The exercise provides a common platform for participants  to learn from each other, build collaborative network systems and to protect  those networks from attack or breakdown.
One of the valuable lessons learned from this mission is  the opportunity to work through cultural and technological differences to  complete the objective, said Senior Master Sgt. David Fleury of the 102nd NWS. 
The Rhode Island airmen have supported Combined Endeavor  since 2003. Five airmen are located at Grafenwoehr, three are assisting the  exercise from a forward site in Romania. 
“Having a forward site in Romania is a good part of the  exercise,” said Marine Maj. David Norton, site commander for Combined  Endeavor-Romania. “It adds to the level of complexity and makes troubleshooting  exponentially harder.”
“The exercise allows me to improve and refresh my  skills,” said Staff Sgt. Miguel Barajas, also of the 102nd. He also said that  he enjoys the camaraderie of the numerous participating nations within the  facility.
Very few missions allow a technician to learn and  encounter so much within a three week period, Combined Endeavor is a great  opportunity, Fleury said.
