To protect people, we need a different type of machine learning

Despite thousands of cybersecurity products, data breaches are at an all-time high. For decades, businesses have focused on securing the machine layer -- layering defenses on top of their networks, devices, and finally cloud applications. But these measures haven't solved the biggest security problem -- an organization's own people. Traditional machine learning methods that are used to detect threats at the machine layer aren't equipped to account for the complexities of human relationships and behaviors across businesses over time. There is no concept of "state" -- the additional variable that makes human-layer security problems so complex.
