Abstract: A method and an apparatus to perform multi-connection traffic analysis and management are described. In one embodiment, the method includes analyzing data packets in the first data flow of a client application for a pattern of interest, where the client application communicates data using first and second data flows. In response to the method detecting a pattern of interest in the first data flow, the method identifies the second data flow and identifies a traffic policy for that second data flow. The method applies the identified traffic policy to the second data flow. Other embodiments have been claimed and described.

Abstract: A method and an apparatus to perform multiple packet payload analysis have been disclosed. In one embodiment, the method includes receiving a plurality of data packets, each of the plurality of data packets containing a portion of a data pattern, determining whether each of the plurality of data packets is out of order, and making and storing a local copy of the corresponding data packet if the corresponding data packet is out of order. Other embodiments have been claimed and described.

Abstract: A global response network collects, analyzes, and distributes “cross-vector” threat-related information between security systems to allow for an intelligent, collaborative, and comprehensive real-time response.

Abstract: Some embodiments of on-the-fly pattern recognition with configurable bounds have been presented. In one embodiment, a pattern matching engine is configured based on user input, which may include values of one or more user configurable bounds on searching. Then the configured pattern matching engine is used to search for a set of features in an incoming string. A set of scores is updated based on the presence of any of the features in the string while searching for the features. Each score may indicate a likelihood of the content of the string being in a category. The search is terminated if the end of the string is reached or if the user configurable bounds are met. After terminating the search, the scores are output.

Abstract: A method and an apparatus request web pages and content rating information thereof have been disclosed. In one embodiment, the method includes receiving a request from a user for a web page, retrieving content rating of the web page in response to the request, and fetching the web page substantially simultaneously with the retrieving of the content rating in response to the request. Other embodiments have been claimed and described.

Abstract: A method and apparatus for identifying data patterns of a file are described herein. In one embodiment, an exemplary process includes, but is not limited to, receiving a data packet of a data stream containing a file segment of a file originated from an external host and destined to a protected host of a local area network (LAN), the file being transmitted via multiple file segments contained in multiple data packets of the data stream, and performing a data pattern analysis on the received data packet to determine whether the received data packet contains a predetermined data pattern, without waiting for a remainder of the data stream to arrive. Other methods and apparatuses are also described.

Abstract: A method and an apparatus request web pages and content rating information thereof have been disclosed. In one embodiment, the method includes receiving a request from a user for a web page, retrieving content rating of the web page in response to the request, and fetching the web page substantially simultaneously with the retrieving of the content rating in response to the request. Other embodiments have been claimed and described.

Abstract: Information concerning a plurality of identified threats provided by a plurality of preselected sources is stored in memory. An e-mail message may be received over a communication network. The received e-mail message is separated into a plurality of components. The stored information is searched to identify a reputation score associated with each of the plurality of components. It is then determined whether the e-mail is a threat based on the identified reputation score of each of the plurality of components. The determination is sent to a designated recipient.

Abstract: Techniques for notification of reassembly-free file scanning are described herein. According to one embodiment, a first request for accessing a document provided by a remote node is received from a client. In response to the first request, it is determined whether a second request previously for accessing the document of the remote node indicates that the requested document from the remote node contains offensive data. If the requested document contains offensive data, a message is returned to the client, without accessing the requested document of the remote node, indicating that the requested document is not delivered to the client.

Abstract: Some embodiments of reassembly-free deep packet inspection (DPD on multicore hardware have been presented. In one embodiment, a set of packets of one or more files is received at a networked device from one or more connections. Each packet is scanned using one of a set of processing cores in the networked device without buffering the one or more files in the networked device. Furthermore, the set of processing cores may scan the packets substantially concurrently.

Abstract: Some embodiments of an efficient string search have been presented. In one embodiment, a string of bytes representing content written in a non-delimited language is received, wherein the content has been classified into a predetermined category. In a single pass through the string of bytes, a set of N-grams is searched for simultaneously. Statistical information on occurrences of the N-grams, if any, in the string of bytes is collected. In some embodiments, a model is generated based on the statistical information, where the model is usable by a content filter to classify content.

Abstract: Some embodiments of cloud-based gateway security scanning have been presented. In one embodiment, some data packets are received sequentially at a gateway device. The data packets constitute at least a part of a file being addressed to a client machine coupled to the gateway device. The gateway device forwards an identification of the file to a remote datacenter in parallel with forwarding the data packets to the client machine. The datacenter performs signature matching on the identification and returns a result of the signature matching to the gateway device. The gateway device determining whether to block the file from the client machine based on the result of the signature matching from the datacenter.
