Abstract
In 2002, the Defense Advanced Research Projects Agency (DARPA) challenged the research community to design and demonstrate an unprecedented level of survivability for an existing US Department of Defense (DoD) information system by combining Commercial-Off-The-Shelf (COTS) technologies with those developed by DARPA. The development team, led by BBN Technologies, produced a solution architecture entitled Designing Protection and Adaptation into a Survivability Architecture (DPASA).
