During the last years several worm epidemics have emerged as major threats to critical digital infrastructures. To make large-scale networks more resilient against these kind of threats, we evaluate the usage of peer-to-peer architectures whereby each peer is responsible for

  • Detecting whether a virus or worm is uncontrollably propagating through the network resulting in an epidemic.
  • Automatically dispatching warnings and information to other peers of a security-focused group.
  • Taking specific precautions for their host by automatically hardening their security measures during the epidemic.
