Abstract:
A variety of techniques are disclosed for detection of advanced persistent threats and similar malware. In one aspect, the detection of certain network traffic at a gateway is used to trigger a query of an originating endpoint, which can use internal logs to identify a local process that is sourcing the network traffic. In another aspect, an endpoint is configured to periodically generate and transmit a secure heartbeat, so that an interruption of the heartbeat can be used to signal the possible presence of malware. In another aspect, other information such as local and global reputation information is used to provide context for more accurate malware detection.

Claim (Index 31):
A computer program product comprising a non-transitory computer readable medium having stored thereon computer executable code that, when executing on one or more computing devices, cause the one or more computing devices to perform the steps of:\n receiving, at a gateway interposed between a second network and an endpoint in an enterprise network separate from the second network and the gateway, a heartbeat addressed to the gateway, the heartbeat including a signal communicated from the endpoint to the gateway, and the heartbeat containing cryptographically secured information including a security health status of the endpoint, the security health status based on monitoring, by a health monitor on the endpoint, software items executing on the endpoint and the security health status indicating an uncompromised security health status when the endpoint is uncompromised; detecting, at the gateway, a change in the security health status included in the heartbeat; following detecting the change of the security health status included in the heartbeat at the gateway, receiving, by the gateway, network traffic other than the heartbeat from the endpoint, the network traffic addressed for forwarding by the gateway via the second network to a second destination address outside the gateway from the enterprise network; and responding to the change of the security health status included in the heartbeat in combination with the network traffic received following the change, the response including blocking, by the gateway, the network traffic other than the heartbeat the endpoint.
