Detecting endpoint compromise based on network usage history
In the context of network activity by an endpoint in an enterprise network, malware detection is improved by using a combination of reputation information for a network address that is accessed by the endpoint with reputation information for an application on the endpoint that is accessing the network address. This information, when combined with a network usage history for the application, provides improved differentiation between malicious network activity and legitimate, user-initiated network activity. |

Remote assistance controller that provides control over what a remote assistor can access
A remote assistance controller serves as an intermediary between a user requesting remote assistance and a remote assistor.

Reprogramming multicast replication using real-time buffer feedback
Methods and systems are described for programming a substitution of ingress replication buffering for egress replication buffering after identifying egress buffer errors (such as overflow) for multicast traffic.

Using virtual output queues in ingress buffers may reduce risk of egress port congestion, as egress buffers have more limited resources than ingress buffers; however, relying solely on ingress replication for multicast traffic may hinder unicast traffic. Ingress buffer replication of multicast traffic may be used selectively and temporarily. |
