The impact of a truly autonomous cyber capability could be profound. The research that will be presented intends to explore the benefits and drawbacks of autonomous cyber capabilities. It presents a method and emphasizes the importance of testing the robustness of the machine learning algorithms which form the basis for autonomous decision making. Robust assessment will help mitigate risks associated with nefarious actors compromising the learning systems. Considerations are also presented concerning the right level of human interaction and the importance of the human machine team. Finally, a brief discussion on how the latest uses of blockchain technologies could be used to improve the security and bound the behavior of cyber autonomous systems are discussed.
