Abstract. Grids should not just be facilitating advances in science and engineering; rather they should also be making an impact on our daily lives by enabling sophisticated applications such as new consumer services and support for homeland defense. This is not possible today because the poor grid dependability—which is tolerated by scientific users—would be unacceptable in critical infrastructure applications. This project aims at correcting this problem by devel oping technology that will allow grids to be used to provide services upon which society can depend. Through the Grid Dependability and Survivability Architecture (GDSA) and the Dependability Exchange and Specification Language (DESL), Grids will be engineered both to achieve high dependability and to permit assurance that high dependability has been achieved.
