Abstract: A device may receive a malicious file associated with a network of network devices and may identify a file type and file characteristics associated with the malicious file. The device may determine one or more rules to apply to the malicious file based on the file type and the file characteristics associated with the malicious file and may apply the one or more rules to the malicious file to generate a partial file signature for the malicious file. The device may provide the partial file signature for the malicious file to one or more of the network devices of the network. The partial file signature may cause the one or more of the network devices to block the malicious file.

Abstract: A network device may be configured to receive a file stream associated with an file. The network device may be configured to identify, based on receiving the file stream, an initial portion of the file. The network device may be configured to process the initial portion of the file to determine one or more features of the file. The network device may be configured to generate, based on the one or more features of the file, a determination as to whether the file is malicious. The network device may be configured to block or allow, based on the determination, the file stream.

Abstract: Methods and apparatus are disclosed which provide a system for secure and reliable communication between client computers residing on separate private networks but connected via a public network such as the Internet. The communications described herein are designed to function even if a persistent link can not be established between the two computers. Further, the systems and apparatus described herein are designed to traverse any locally installed gateways or firewalls to obtain access to a remote destination.

Abstract: Methods and apparatus are disclosed which provide a system for accurate time and usage based metering of client application or client application feature usage and the reporting of said usage to a site on a public network. The present invention can be used as an alternative to traditional license granting systems, or be used for any other purpose where tracking and metering of valuable resources or services is useful. While the current invention can provide metering and billing capability to software applications akin to the billing systems deployed by telecommunication companies for line and feature usage, the metering can also emulate traditional licensing models and operate in conjunction with traditional licensing systems.
