Abstract: The present disclosure includes methods and systems for multi-domain information sharing. One or more embodiments can include a computing device with a VMM hosting a first information domain VM, a second information domain VM, and a cross-domain solution VM that controls information transfer between the first information domain VM and the second information domain VM. One or more embodiments can also include a hypervisor to enforce an isolation policy within the system.

Abstract: A device to prevent, detect and respond to one or more security threats between one or more controlled hosts and one or more services accessible from the controlled host. The device determines the authenticity of a user of a controlled host and activates user specific configurations under which the device monitors and controls all communications between the user, the controlled host and the services. As such, the device ensures the flow of only legitimate and authorized communications. Suspicious communications, such as those with malicious intent, malformed packets, among others, are stopped, reported for analysis and action. Additionally, upon detecting suspicious communication, the device modifies the activated user specific configurations under which the device monitors and controls the communications between the user, the controlled host and the services.
