Cybersecurity threats are growing exponentially.  Better cybersecurity approaches are needed to defend critical infrastructures. There is also a need to better understand the cyber threats and develop effective mitigation solutions holistically. This drives the need for AI-based vulnerability assessment and predictive analytical capabilities.  Lockheed Martin (LM) is now applying its technical know-hows to cyber artificial intelligence (AI); Aalto University has developed cyber-attack graph capabilities. The LM and Aalto teams performed a joint research to explore different what-if attack scenarios.
