US Patent 9462007 Human user verification of high-risk network access

Systems and methods for performing a human user test when a high-risk network access is captured by an intermediary security device are provided. According to one embodiment, network security application includes a network traffic control module, a human user test engine and a risk management module. The network traffic control module identifies a high-risk network access initiated by a device associated with a private network protected by the network security appliance. The human user test engine (i) sends a human user test message to the human user of the device to verify that the high-risk network access was initiated by or is otherwise authorized by the human user of the device; receives a response to the human user test message; and (iii) determines whether the response is a correct response to the human user test message. The risk management module allows the high-risk network access when the response is correct.
