Artificial Immunization in Hierarchical and Peer-to-Peer Networks to Protect Against Cyber Threats

Immunization approaches for cyber-physical systems based on hierarchical and peer-to-peer network topologies are described. A systematic analysis of existing immunization methods based on graph theory is carried out, together with theoretical formalization and experimentation. The approach demonstrates sufficient effectiveness of artificial immunization using global strategies for cyber-physical systems based on a hierarchical network infrastructure.
