Survivability and Simulation

The past few years have shown a need for fundamentally new approaches to the security and survivability of large scale networked systems. Infrastructures and other modern systems pose problems that arise from many factors: partial information, complexity of combined interactions of very large numbers of human and automated participants, ubiquitous access, loss of centralized administrative control, the growing threat of automated attacks, and a shift in priorities for security from confidentiality of information to availability of services. Survivability research seeks new methods, including emergent algorithms, diversity, and dynamic trust validation, to ensure that systems satisfy their most critical requirements. Easel is an automated simulation tool for research in survivability, infrastructure assurance, and other applications that must contend with incomplete and imprecise information.
