  • Patent number: 12238825
    Abstract: The present disclosure distributes processing capabilities throughout different nodes in a wireless network. Methods and apparatus consistent with the present disclosure increase the efficiency of communications in a wireless network because they help minimize the need to forward communications to other nodes in the network. Apparatus and methods consistent with the present disclosure perform a function of elastic content filtering because rating information may be stored in different memories of different mesh nodes according to rules or profiles associated with a wireless mesh network as responses to requests are sent back along a route in a wireless mesh network in a manner that may not increase an amount of network traffic. When, however, network traffic dips below a threshold level, additional messages may be sent to certain mesh nodes that update rating information stored at those certain mesh nodes.

  • Patent number: 12169564
    Abstract: The present disclosure is directed to analyzing received sets of computer data. Methods and apparatus consistent with the present disclosure may forecast that a received set of computer data does not include malware after allowing instructions included in that set of computer data to execute for an amount of time that does not exceed an allocated amount of time. Methods consistent with the present disclosure may instrument a set of received program code and allow instructions in that received set of program code to execute as instrumentation code collects information about the set of program code. This collected information may be compared with sets of known good data when determining whether a received set of program code is likely not to include malware. This collected information may be associated with “behaviors” performed by the received set of program code that may be identified using sets of contextual data.

  • Patent number: 12074863
    Abstract: Methods and apparatus consistent with the present disclosure may prevent a computer process from failing when a firewall located between a client device and a server identifies that a process at the firewall should be bypassed using fingerprint information associated with a connection attempt. When fingerprint information stored at a firewall matches previously received fingerprint information, the firewall may allow processes typically performed at the firewall to be bypassed, thereby, allowing communications to pass between the client device and the server without inspection. When that fingerprint information does not match previously received fingerprint information, the firewall may perform a process that causes the client device to fail the first connection attempt. Because of this, methods consistent with the present disclosure may allow communications from an application program to be passed through a firewall without relying on an ever growing list of trusted application programs.

  • Patent number: 12069480
    Abstract: The present disclosure distributes processing capabilities throughout different nodes in a wireless network. Methods and apparatus consistent with the present disclosure increase the efficiency of communications in a wireless network because they help minimize the need to forward communications to other nodes in the network by allowing different wireless nodes to receive and store content ratings regarding requested content in caches associated with respective wireless nodes. Apparatus and methods consistent with the present disclosure perform a load balancing function because they distribute content ratings to different nodes in a wireless network without increasing messaging traffic. As response messages regarding access requests are passed back to a requestor, cache memories at nodes along a communication path are updated to include information that cross-references data identifiers with received content ratings.
