Predictive Modeling for Insider Threat Mitigation
This project, funded by PNNL’s Laboratory Directed Research and Development Program is conducted under the Predictive Defense focus area of the Laboratory’s Information and Infrastructure Integrity Initiative. The current practice for addressing the insider cyber threat is to monitor the network and individual systems to identify when someone is not following established policy or is abusing their authorized level of access in a way that is harmful to the organization. The study takes many different approaches in order prevent inside threats.
