Abstract: A system and method for building an executable script for performing a network security audit is described. A source program expressed in a network packet simulation language is stored. The same program includes a plurality of statements encoding logic to simulate an exchange of network protocol compliant-packets. Each statement is scanned into a sequence of individual tokens. Each token is parsed into grammatical phrases comprising at least one of an expression and a control construct. Each expression evaluates a data value. Each control construct defines a process flow. The grammatical phrases are compiled into program instructions to execute the logic on a target machine.

Abstract: A system, method and computer program product are provided for adaptive priority data filtering. Data is collected from a network segment and classified into multiple flows. The flows are prioritized into high and low priority flows. High priority flows are stored in a high priority queue prior to processing, while low priority flows are stored in a low priority queue prior to processing. An amount of data in the high priority flows is monitored. Buffers from the low priority queue are reallocated to the high priority queue if the amount of data in the high priority flows surpasses a predetermined threshold.

Abstract: A system and method for efficiently managing computer virus definitions using a structured virus database are described. One or more virus definition records are stored in a structured virus database. Each virus definition record includes an identifier uniquely identifying a computer virus, at least one virus name associated with the computer virus, a virus definition sentence including object code providing operations to detect the identified computer virus within a computer system, and a virus removal sentence including object code providing operations to clean the identified computer virus from the computer system. The virus definition records in the structured virus database are accessed indexed by the identifier and the at least one virus name for each virus definition record. The object code of the virus definition sentence and the virus removal sentence for each accessed virus definition record is interpreted.

Abstract: An Internet computer system with methods for dynamic filtering of hypertext tags and content is described. The system includes one or more Web clients, each operating a Web browser (e.g., Netscape Navigator or Microsoft Internet Explorer) with an Internet connection to one or more Web servers. Each client includes, interposed between its browser and communication layer, a Filter module of the present invention which traps and processes all communications between the browser and the communication layer. The Filter module, which implements client-side methodology at each individual Web client for dynamic filtering of hypertext tags and content, includes an output stream, a processing loop, a Filter method, and an input stream. During system operation, the Web browser generates multiple requests for retrieving content. More particularly, particular content is retrieved by a fetch or GET command (e.g., using HTTP protocol) transmitted to a target server from the client-side communication layer (e.g.

Abstract: A method and system for on-access virus scanning within an enterprise or in a workgroup, where all users are authenticated against a trusted certificate authority. The first time an item, such as an executable file or document, is accessed, it is scanned for viruses, worms, trojan horses, or other malicious code, and, after the item is determined to be free from threats or is corrected, a certificate noting this information is generated. At the same time a Globally Unique Identifier (“GUID”) is generated and appended to the item. The certificate contains various information, including the identity of the scanner that performed the virus check, as well as a means for determining if the original item has been altered since it was scanned, and is stored in a certificate database. The GUID is used as a pointer for locating the certificate. A subsequent user who accesses the item will detect the GUID and can use the GUID to locate the certificate for the item.

Abstract: A method for improving the performance and responsiveness of a computer program is presented. The system consists of a read-ahead mechanism that scans current data-sets and reads data-sets referenced within the current data-set prior to any actual request or access to the data set by the system. The determination of which data sets to access is made based upon a prioritization computed either through user defined settings or through heuristic observation of the system's behavior. The present invention has particular value in connection with Internet communications and access to remote data.

Abstract: The invention is directed to a method and apparatus for preventing software piracy. A license enforcement server may be integrated with an operating system running on a network-critical machine. As such, other computational devices connected to the network may obtain permission to perform licensed activities. These computational devices may have an instruction set for communicating with the license enforcement server. Further, the license enforcement server may communicate with a licensing organization. The license enforcement server may utilize a namespace tree to organize licenses and uniquely identify licensed activities. In this manner, a universal license enforcement system may be achieved in which disabling of the license enforcement mechanisms would adversely effect a network.

Abstract: The invention provides for on-access scanning of archives, such as “ZIP” files, for files containing viruses or other unwanted characteristics. In particular, disclosed are various techniques for beginning a scanning operation, and then monitoring the scanning operation to determine whether it is completing in a reasonable time. If the scanning operation is taking place within a terminal server type of environment, such as the Microsoft Terminal Server, where an application program is run in a virtual execution environment, then provision is made to identify client connections to the server so that error messages (such as denying file access due to a virus) can be presented to a terminal server client's terminal, rather than at the terminal server console.
