  • Patent number: 10425234
    Abstract: A new approach is proposed to support monitoring Perfect Forward Secrecy (PFS) network traffic by utilizing a hardware security module (HSM) appliance. Here, the HSM appliance is a high-performance, Federal Information Processing Standards (FIPS) 140-compliant security hardware with embedded firmware, which can be used for management and sharing of ephemeral keys used in a secured PFS communication session between two parties. Specifically, the HSM allows a server to share one or more of its ephemeral keys and/or parameters used in PFS traffic during the session with a third party under specified access rights and/or authorization, wherein the third party can be but is not limited to a traffic monitoring module. The HSM allows the third party to access the ephemeral keys stored on the HSM under the specified access rights and/or authorization so that the third party may decrypt and run analytics on the PFS traffic captured during the session.

  • Patent number: 10182063
    Abstract: Architectures and techniques for in-app behavior detection. A behavior detection agent within an application running on a hardware computing device captures events within the application. The events are inputs received from one or more sources external to the application. The behavior detection agent generates an event stream from the captured events. The behavior detection agent analyzes the event stream for significant feature frequencies and associations corresponding to one or more attack profiles. The behavior detection agent initiates an attack response in response to finding one or more significant feature frequencies and associations. The attack response comprises at least changing an operational configuration of the application.
