A method for processing network traffic data includes receiving a packet, and determining whether the packet is a previously dropped packet that is being retransmitted. A method for processing network traffic content includes receiving a plurality of headers, the plurality of headers having respective first field values, and determining whether the first field values of the respective headers form a first prescribed pattern. A method for processing network traffic content includes receiving a plurality of packets, and determining an existence of a flooding attack without tracking each of the plurality of packets with a SYN bit.

Detecting and preventing flooding attacks in a network environment

A method and apparatus for managing a transfer of data in a data network identifies data associated with a communication session between a first node and a second node in the data network. Further processing of the communication session occurs when a portion of the communication session meets a criterion and the communication session is permitted to continue when the portion of the communication session does not meet the criterion.

Managing transfer of data in a data network

An integrated security switch and related method for managing connectivity and security among networks. The integrated security switch includes a security function connectable with a first network and at least one switching function connectable with a second network. A common management interface driven by both command line interface and graphic user interface protocols manages the switching function via a management path dedicated between the security function and the switching function. The common management interface enables secure switching of traffic to flow via a traffic path dedicated between the switching function and the security function. Typically, the traffic is a flow of data between the Internet and a group of networked users such as a wide area network.

Integrated security switch

Various embodiments illustrated and described herein include systems, methods and software for content type classification. Some such embodiments include determining a potential state of classification for packets associated with a session based at least in part on a packet associated with the session that is a packet other than the first packet of the session.

A cloud security service is made available to endpoint computers. Network traffic from originating application programs running on endpoint computers are redirected to the cloud security service based on characteristics of the originating application programs. Network traffic from an originating application program may be redirected to the cloud security service by way of a virtual private network (VPN) tunnel or generic routing encapsulation (GRE) tunnel between an endpoint computer and a cloud computing system hosting the cloud security service, for example. Network traffic from an originating application program may also be routed from an endpoint computer to a gateway system, and then redirected from the gateway system to the cloud computing system. The cloud security service may drop or forward network packets of the network traffic depending on a result of scanning the network packets.

Application-based network traffic redirection for cloud security service

One embodiment relates to a computer-implemented method of preemptively scanning targets for malicious codes. Input qualities regarding said targets are received. A first computer-implemented procedure is applied to generate a measure of priority for scanning of said targets. Targets are selected for preemptive scanning using said measure of priority. In addition, resource utilization inputs may be received, and a second computer-implemented procedure may be applied to determine a system resource usage level using the resource utilization inputs. In that case, the malware scanning may be performed opportunistically based on the system resource usage level. Other embodiments, aspects and features may also be disclosed.
