Mithril: Adaptable Security for Survivability in Collaborative Computing Sites

Scientific computing sites enable collaborations over the Internet but also face increased risks from malicious parties. Ensuring availability of computing services at these sites is critical for scientists and engineers across the world and requires addressing the challenges of openness, usability, performance, and compatibility. We have developed an approach for survivability of sites using adaptable security mechanisms that address these challenges. Using this approach we have develop tools that tackle immediate threats facing open sites as illustrated in recent events
