Building a distributed security defence system

Given the complexity of infrastructures current state of security technology and the limited budgets any security defense systems can be outnumbered by a sufficient number of random sequential failures, e.g. due to multiple DOS attacks. Complementary to the regular solutions where per node several identical dedicated nodes are added (i.e. redundants), a resource sharing approach between undedicated nodes is aimed to build a large scale cluster of redundants and approximate perpetual availability of security distributing nodes. In this paper principles are acquired from related and unrelated fields to build a distributed defense system (DDS) that relies on resource sharing. The proposed protocol set, called Medusa, achieves this DDS by dissociating trust authority from identity and hardware, making trust a moveable emancipated commodity. As a moveable object trust can apply traditional fault tolerance techniques by process migration.
