Satellite Cyber Immune Response to Evolving Threats

Solutions to space cyber defense must combine a high degree of autonomy with the ability to address emergent threats while fitting within a tight resource budget. Bio-inspired solutions such as an Artificial Immune System (AIS) for cyber defense can leverage analogues between malicious cyber activity and exogenous biological immune triggers to provide a response. Among these analogues are threat detection, non-localized systems-of-systems under threat, large data volumes and speeds, and threat evolution. Bio-inspired solutions show added value beyond traditional algorithms: efficiency, optimization, and automation. The network of collaborative entities within the Biological Immune System (BIS) provides a blueprint to emergent intelligence upon which the Cyber Immune Response System (CIS) can be formed.
