System and method for communicating coalesced rule parameters in a distributed computing environment
Patent number: 6920493Abstract: A system and a method for communicating coalesced rule parameters in a distributed computing environment are described. A plurality of packet validation devices are communicatively interposed between network routing points within the distributed computing environment. The packet validation devices apply parameterized rules to transiting network packet traffic. A plurality of processing tree nodes are configured into a concast tree. In a lowermost layer of the concast tree, each processing tree node collects and coalesces rule parameters from at least one packet validation device. In each successive layer of the concast tree, each processing tree node collects and coalesce the rule parameters from at least one processing tree node in a next lower layer of the concast tree. A control center assembles the coalesced rule parameters from each packet validation device in an uppermost layer of the concast tree.Type: GrantFiled: March 19, 2001Date of Patent: July 19, 2005Assignee: Networks Associates Technology, Inc.Inventor: Stephen A.

Patent number: 6920558Abstract: One embodiment of the present invention provides a system for managing security policies in a distributed computing system. Security policies include, but are not limited to, a firewall policy, a policy for file access, a policy for application access, a policy for an encryption algorithm, a policy for audit trails, and a policy for activity logging. These security policies determine access rights to a computer application. The system operates by creating multiple security policies with individual security policies specifying a differing level of security for the distributed computing system. These security policies are then distributed to each computer in the distributed computing system. Next, a specific security policy is selected for use across the distributed computing system, and each computer in the distributed computing system is directed to use the specified security policy enforcing a selected security posture.Type: GrantFiled: May 22, 2001Date of Patent: July 19, 2005Assignee: Networks Associates Technology, Inc.Inventors: David L.

Publication number: 20050154900Abstract: A stream 14 of external computer program calls made from an application program 2 to an operating system 4 is logged by an anti-malware layer 8. This stream 14 is examined for a primary set XYZ of external program calls known to be associated with malicious computer program activity. When such a primary set XYZ of external computer program calls is identified, the malicious activity is blocked and the logged stream 14 is examined to determine one or more secondary sets of external program calls which are now added to the set of rules 10 against which the logged stream 14 of external program calls is tested. In this way the set of rules 10 is dynamically adapted so as to more rapidly and proactively identify malicious computer program activity.Type: ApplicationFiled: January 13, 2004Publication date: July 14, 2005Applicant: NETWORKS ASSOCIATES TECHNOLOGY, INC.Inventor: Igor Muttik

Patent number: 6907396Abstract: One embodiment of the present invention provides a system for emulating computer viruses and/or malicious software that operates by patching additional program instructions into an emulator in order to aid in detecting a computer virus and/or malicious software within suspect code. During operation, the system loads a first emulator extension into the emulator. This first emulator extension includes program instructions that aid in the process of emulating the suspect code in order to detect a computer virus and/or malicious software. The system also loads the suspect code into an emulator buffer. Next, the system performs an emulation using the first emulator extension and the suspect code. This emulation is performed within an insulated environment in a computer system so that the computer system is insulated from malicious actions of the suspect code. During this emulation, the system determines whether the suspect code is likely to exhibit malicious behavior.Type: GrantFiled: June 1, 2000Date of Patent: June 14, 2005Assignee: Networks Associates Technology, Inc.Inventors: Igor Muttik, Duncan V.

Patent number: 6904521Abstract: A technique, and system(s) implementing the technique, allow an encrypted message to be sent directly to a recipient, and when the recipient opens the message, the recipient's system sends a request to an arbiter server to retrieve decryption information to decrypt the message. When the arbiter server receives the request for the decryption information, the arbiter server generates evidence of the request and sends the decryption information to the recipient. In this way, an evidentiary trail, that cannot be repudiated, can be used to establish that the recipient received and attempted to open the message.Type: GrantFiled: February 16, 2001Date of Patent: June 7, 2005Assignee: Networks Associates Technology, Inc.Inventor: Andrey Jivsov

Patent number: 6898712Abstract: A library of anti computer virus test drivers is provided with classifications for the drivers which may be used to select the applied drivers in dependence upon which anti computer virus program is using that library. The library is typically shared between a suite of anti computer virus programs. The drivers are also classified with information that allows them to be placed in a priority order for application when scanning. In this way, the drivers that protect against the most threatening viruses may be checked for first and accordingly the highest level of protection achieved if the scanning process is early terminated.Type: GrantFiled: February 20, 2001Date of Patent: May 24, 2005Assignee: Networks Associates Technology, Inc.Inventors: James Malcolm Vignoles, Paul Nicholas Gartside, Barrett Tuttle
