  • Patent number: 7062555
    Abstract: A system and method for distributed function discovery with third party responses in a peer-to-peer network to facilitate efficient use of bandwidth and resources are disclosed. The method for secure automatic selection of a designated service provider in a peer-to-peer network generally comprises broadcasting a digitally signed election initiating packet containing a value for at least one criteria by a sending node, awaiting response time-out period expiry or receipt of a response election packet, broadcasting a digitally signed election result packet indicating the sending node is the designated service provider if response time-out period expiry occurs prior to receipt of a response election packet, and awaiting for, verifying, and storing election result in an election result broadcast if receipt of a response election packet occurs prior to expiry of response time-out period.

  • Patent number: 7013330
    Abstract: A source computer 2 having a copy of a computer file that it is desired to download to a plurality of target computers issues broadcast messages via a computer network linked to those target computers. The broadcast messages indicate the availability of the computer file for download and include a download qualifying parameter. The download qualifying parameter is used by receiving target computers to determine whether or not they qualify to attempt a download from the source computer in response to the received broadcast message. Only those target computers that do qualify attempt a download. The source computer monitors how many target computers make a download attempt in response to a particular broadcast message and adjusts the download qualifying parameters in subsequent broadcast messages so that the target computers progressively download the new computer file without overloading the source computer.

  • Patent number: 6983380
    Abstract: One embodiment of the present invention provides a system that automatically generates a valid behavior specification for use in an intrusion detection system for a computer system. The system operates by receiving an exemplary set of system calls that includes positive examples of valid system calls, and possibly negative examples of invalid system calls. The system automatically constructs the valid behavior specification from the exemplary set of system calls by selecting a set of rules covering valid system calls. This set of rules is selected to cover all positive examples in the exemplary set of system calls without covering negative examples. Moreover, the process of selecting a rule for the valid behavior specification involves using an objective function that seeks to maximize the number of positive examples covered by the rule while seeking to minimize the number of possible system calls covered by the rule.

  • Patent number: 6968461
    Abstract: A computer virus scanning system is described in which during the scanning operation a measurement value indicative of the amount of data processing performed is calculated and this measurement value used to trigger breaks in the virus scanning operation. The triggered breaks can be used to perform a determination as to whether or not the virus scanning operations should be early terminated. One possibility is to measure the total size of the data processed during the virus scanning operation and calculate a ratio of this compared to the size of the computer file being virus scanned. If this calculated ratio exceeds a predetermined threshold, then virus scanning may be terminated. Another possibility is to associate a complexity value with each of a plurality of tests applied in the virus scanning operation. A total for these complexity values may be used to trigger the breaks and also to trigger early termination upon exceeding of respective threshold levels.

  • Patent number: 6950947
    Abstract: Two or more computers acting as firewalls share network state data to enhance throughput performance. A firewall creates a separate common TCP control block (CCB) for each group of TCP connections through the firewall having common endpoints. The CCB is a shared data structure comprising a single microstate shared across the group of TCP connections. Each such individual TCP connection has a TCP control block, which instead of a microstate, contains a pointer to the appropriate CCB. Preferably, each firewall receives CCBs from its peers and stores them. Each firewall preferably adjusts data traffic passing through it based on the CCBs stored within it. By adjusting traffic to reduce or eliminate congestion, throughput is enhanced.

  • Patent number: 6947986
    Abstract: A system and method for providing Web-based remote security application client administration in a distributed computing environment is described. A self-extracting configuration file is stored. The self-extracting configuration file contains an executable configuration file that is self-extractable on a target client into an administered security application. An executable control is embedded within an active administration Web page. The executable control is triggered upon each request for the active Web page and causes dynamic Web content to be generated therefrom. A Web portal including the active administration Web page is exported to a browser application independent of a specific operating environment. The executable control is interpreted to facilitate copying of the self-extracting configuration file to the target client.

  • Patent number: 6944775
    Abstract: A system, method and computer program product are provided for scanning data utilizing multiple scanning engines. Initially, a request for data to be scanned for viruses is generated utilizing a scanning interface. Thereafter, such request to scan data is sent to a plurality of scanning engines utilizing an engine interface application control module coupled between the scanning interface and the scanning engines. The request is adapted for prompting the scanning engines to scan the data and respond with events upon locating a virus. Such events are then received utilizing an event processor module coupled to the scanning engines and the engine interface application control module for processing the events. The processed events are then sent to the engine interface application control module for being monitored by the scanning interface.

  • Patent number: 6938161
    Abstract: 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.
