A multiple network protocol encoder/decoder comprising a network protocol layer, data handler, O.S. State machine, and memory manager state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine which decodes network protocols such as TCP, IP, User Datagram Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler which consists of data state machines that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML). Each data state machine reacts accordingly to the pertinent data, and any data that are required by more than one data state machine is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location with a pointer designating such data (thereby ensuring minimal memory usage). Resulting display data are immediately passed to a display controller. Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

A networking protocol includes definitions of quality of service enhancements to provide reliable multimedia data stream connections in wireless computer networks. These enhancements may be implemented as extensions to packet headers, such as a multimedia control field made up of various sub fields.

Methods, systems, and computer program products for insider threat detection are provided. Embodiments detect insiders who act on documents and/or files to which they have access but whose activity is inappropriate or uncharacteristic of them based on their identity, past activity, and/or organizational context. Embodiments work by monitoring the network to detect network activity associated with a set of network protocols; processing the detected activity to generate information-use events; generating contextual information associated with users of the network; and processing the information-use events based on the generated contextual information to generate alerts and threat scores for users of the network. Embodiments provide several information-misuse detectors that are used to examine generated information-use events in view of collected contextual information to detect volumetric anomalies, suspicious and/or evasive behavior. Embodiments provide a user threat ranking system and a user interface to examine user threat scores and analyze user activity.

The present invention provides the benefits of negotiated network resources to session-unaware applications. When a session-unaware application runs on a mobile device, the device, knowing that the application is session-unaware, negotiates appropriate network-policy parameters for the application. The application remains unaware, but it receives the benefits of the network-policy parameter negotiation. The network-policy parameter negotiation is carried on between the mobile device and a “network policy mediator” in the network. Together, they reserve the appropriate network resources and secure the appropriate guarantees. In some embodiments, a software “shim” runs in the network-protocol stack on the mobile device. By intercepting network-access attempts sent by the session-unaware application, the shim knows to begin the network-policy parameter negotiation. In some embodiments, the mobile device downloads information about session-unaware applications from the network. This information includes a list of which network-policy parameter guarantees would be most beneficial to each application.

The invention relates to network based content inspection (NBCI). More specifically, the invention provides systems and methods for improved NBCI in complex networks that are typical for enterprises and service providers. These networks are shared by large numbers of concurrent users who send and retrieve application content of various sizes via a variety of communication protocols. This invention improves the efficiency of the NBCI of an individual communication session by learning from the processing results of other communication sessions which may be carried via different network protocols. In addition, the invention provides methods that do not weaken the overall security for the network and that improve the stability of NBCI systems by minimizing the risk of system resource exhaustion if subjected to a burst of large payloads. The invention also improves perceived network stability by preventing the system resources from being “live-locked” by a few large content inspection tasks. Further still, the invention improves the cost-effectiveness of NBCI by allowing the optimization knowledge gained by one NBCI node be shared with other nodes.
