Abstract: Systems and methods are disclosed herein for verifying the integrity of a remote computing device. The system includes a challenge processor in communication with a communication device. The challenge processor selects a challenge from a plurality of challenges for determining the integrity of a computer program on a remote computing device. The challenge is selected in a manner which is substantially unpredictable by the remote computing device. The communication device transmits the challenge to the remote computing device and receives an output of the challenge. The challenge processor is also configured to determine from the output of the challenge whether the integrity of the computer program on the remote computing device has been compromised.

Abstract: Systems and methods are disclosed herein for detecting a threat to a computing device. The system includes a server and a computing device in communication with the server and configured to browse the Internet. The server receives data indicating a configuration parameter of the computing device and executes an emulation of the computing device that replicates the configuration parameter. The server also receives data relating to the computing device's browsing behavior and replicates the browsing behavior on the emulation. Upon detecting an undesired modification to the emulation of the computing device caused by the replicated browsing behavior, the server automatically generates and outputs an alert related to the undesired modification and related browsing behavior.
