Abstract: When security-related behavior is detected on an endpoint, e.g., through a local security agent executing on the endpoint, a threat management facility associated with the endpoint can interact with a user via a second local security agent on a second endpoint in order to solicit verification, authorization, authentication or the like related to the behavior. In one aspect, an administrator for an enterprise managed by the threat management facility may verify, authorize, or otherwise approve the detected behavior using this technique. In another aspect, a user of the device may use this infrastructure to approve of a potentially risky behavior on one device by using a verification procedure on a second device associated with the user.
