Abstract
Described systems and methods allow malware-protecting a client system (e.g., computer system, smartphone, etc.) connected to a network. In some embodiments, a network appliance transmits a boot image over the network, on demand, to the client system. The boot image may install a hypervisor, which may further load a local OS and applications into a virtual machine. The client system performs a mutual integrity attestation transaction with the network appliance over the network, wherein each side of the transaction verifies the integrity of software objects executing on the other side. When the network appliance determines that the client system is not in a trusted state, the network appliance may block access of the client system to the network. When the client system determines that the network appliance is not in a trusted state, the client system may block communications between the client system and the network appliance.
