Patent number: 9075804Abstract: 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.Type: GrantFiled: November 17, 2014Date of Patent: July 7, 2015Assignee: Dell Software Inc.Inventors: Thomas E. Raffill, Shunhui Zhu, Roman Yanovsky, Boris Yanovsky, John Gmuender

Patent number: 9065848Abstract: 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.Type: GrantFiled: October 28, 2013Date of Patent: June 23, 2015Assignee: Dell Software Inc.Inventors: Aleksandr Dubrovsky, John Everett Gmuender, Boris Yanovsky, Roman Yanovsky, Shunhui Zhu

Publication number: 20140373156Abstract: 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.Type: ApplicationFiled: September 2, 2014Publication date: December 18, 2014Inventors: Aleksandr Dubrovsky, Igor Korsunsky, Roman Yanovsky, Boris Yanovsky

Publication number: 20140324415Abstract: 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.Type: ApplicationFiled: July 8, 2014Publication date: October 30, 2014Inventors: Thomas E.

Publication number: 20140089249Abstract: Techniques for data pattern analysis using deterministic finite automaton are described herein. In one embodiment, a number of transitions from a current node to one or more subsequent nodes representing one or more sequences of data patterns is determined, where each of the current node and subsequent nodes is associated with a deterministic finite automaton (DFA) state. A data structure is dynamically allocated for each of the subsequent nodes for storing information associated with each of the subsequent nodes, where data structures for the subsequent nodes are allocated in an array maintained by a data structure corresponding to the current node if the number of transitions is greater than a predetermined threshold. Other methods and apparatuses are also described.Type: ApplicationFiled: December 4, 2013Publication date: March 27, 2014Applicant: SONICWALL, INC.Inventors: Aleksandr Dubrovsky, Justin Michael Brady, Roman Yanovsky, Boris Yanovsky
