Application phenotyping
A collection of techniques is disclosed to allow for the detection of malware that leverages pattern recognition and machine learning to effectively provide “content-less” malware detection, i.e., detecting a process as being an ‘anomaly’ not based on its particular content, but instead based on comparisons of its behavior to known (and characterized) ‘trusted’ application behaviors, i.e., the trusted applications' “phenotypes” and/or the phenotypes of known malware applications. By analyzing the patterns of normal behavior performed by trusted applications as well as malware applications, one can build a set of sophisticated, content-agnostic behavioral models (i.e., “application phenotypes”)—and later compare the processes executed on a user device to the stored behavioral models to determine whether the actual measured behavior reflects a “good” application, or if it differs from the stored behavioral models to a sufficient degree and with a sufficient degree of confidence, thus indicating a potentially malicious application or behavior. |

Layer 4 switching for persistent connections
This disclosure provides for a Layer 4 switching approach wherein a set of L4 switches are organized into a cluster so as to act as a single (or “big”) Layer 4 switch. Connections between the L4 switches are carried out, e.g., using Layer 2 switches. To this end, an intra-cluster routing entity of the switch maintains mapping information (e.g., in a database, or set of data structures) about connections that have been established by the individual switches within the cluster. In this approach, each host (itself a switch) preferably acts like a group of ports of the larger (big) switch. This obviates having each member host from having to maintain connections to many possible destinations. Rather, the intra-cluster routing entity maintains the information about which hosts (and its ports) are connected to which destinations, and the connections are re-used as necessary, even if connections on one side of the “big” switch ceased being used. |
