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.

Abstract: A firewall may identify a uniform resource locator (URL) being transmitted to a user device, the URL link pointing to a host system. The firewall can then modify the URL link to point instead to a sandbox system. Once a user at the user device selects the URL link (e.g., by clicking or touching it in a browser), the firewall receives the user device's HTTP request and directs it to the sandbox system, which generates a new HTTP request that is then sent through the firewall to the host system. The host system then sends host content to the sandbox system instead of to the user device. The user device may then be presented with a representation of the host content as rendered at the sandbox system (e.g., through a remote desktop interface).

Abstract: Methods and apparatus consistent with the present disclosure may be performed by a Cloud computing device may use instrumentation code that remains transparent to an application program that the instrumentation code has been injected into, may perform deep packet inspection (DPI) on computer data, or identify a content rating associated with computer data. In certain instances, data sets that include executable code may be received via packetized communications or be received via other means, such as, receiving a file from a data store. The present technique allows one or more processors executing instrumentation code to monitor actions performed by the program code included in a received data set. Malware can be detected using exception handling to track memory allocations of the program code included in the received data set. Furthermore, access to content associated with malware, potential malware, or with inappropriate content ratings may be blocked.

Abstract: An appliance works in conjunction with an agent on a remote device to control application access to a corporate network. In conjunction with an SSL tunnel and policy operating at the appliance, granular application control may be implemented. In particular, a device user may determine what applications from a set of applications may access the corporate network and which applications do not access the network. The applications may be analyzed to determine whether the application is good or bad, as what security configurations, approvals and denials are associated with the application.

Abstract: Some embodiments of reassembly-free deep packet inspection (DPD on multicore hardware have been presented. In one embodiment, a set of packets of one or more files is received at a networked device from one or more connections. Each packet is scanned using one of a set of processing cores in the networked device without buffering the one or more files in the networked device. Furthermore, the set of processing cores may scan the packets substantially concurrently.

Abstract: Some embodiments of cloud-based gateway security scanning have been presented. In one embodiment, some data packets are received sequentially at a gateway device. The data packets constitute at least a part of a file being addressed to a client machine coupled to the gateway device. The gateway device forwards an identification of the file to a remote datacenter in parallel with forwarding the data packets to the client machine. The datacenter performs signature matching on the identification and returns a result of the signature matching to the gateway device. The gateway device determining whether to block the file from the client machine based on the result of the signature matching from the datacenter.

Abstract: The present disclosure relates to a system, a method, and a non-transitory computer readable storage medium for deep packet inspection scanning at an application layer of a computer. A method of the presently claimed invention may scan pieces of data received out of order without reassembly at an application layer from a first input state generating one or more output states for each piece of data. The method may then identify that the first input state includes one or more characters that are associated with malicious content. The method may then identify that the data set may include malicious content when the first input state combined with one or more output states matches a known piece of malicious content.

Abstract: A method and an apparatus to perform multi-connection traffic analysis and management are described. In one embodiment, the method includes analyzing data packets in the first data flow of a client application for a pattern of interest, where the client application communicates data using first and second data flows. In response to the method detecting a pattern of interest in the first data flow, the method identifies the second data flow and identifies a traffic policy for the second data flow. The method applies the identified traffic policy to the second data flow. Other embodiments have been claimed and described.

Abstract: The present disclosure relates to securely setting up mesh networks in a manner that does not require a physical network cable being attached to a wireless mesh device and that does not require transmitting unencrypted information wirelessly when a mesh network is setup. Methods and apparatus consistent with the present disclosure may allow a user to choose which mesh nodes can join a network and that user may specificity a custom profile that may include rules that may identify how mesh network identifiers are used, that identify passcodes/passphrases assigned to a particular network, may identify types of traffic that may be passed through particular 802.11 radio channels, or other parameters that may control how traffic is switched between devices in a particular wireless mesh network. This combined with dual factor verification and the use of different types of communication channels make wireless mesh networks easy to deploy and expand.

Abstract: The present disclosure is directed to preventing computer data from being usurped and exploited by individuals or organizations with nefarious intent. Methods and systems consistent with the present disclosure may store keys and keying data for each of a plurality of connections in separate memory locations. These memory locations may store data that maps a virtual address to a physical memory address associated with storing information relating to a secure connection. These separate memory locations may have a unique instance for each individual communication connection session, for example each transport layer security (TLS) connection may be assigned memory via logical addresses that are mapped to one or more physical memory addresses on a per-core basis. Such architectures decouple actual physical addresses that are used in conventional architectures that assign a single large continuous physical memory partition that may be accessed via commands that access physical memory addresses directly.

In certain instances, data sets that include executable code may be received via packetized communications or be received via other means, such as, receiving a file from a data store. The present technique allows one or more processors executing instrumentation code to monitor actions performed by the program code included in a received data set. Malware can be detected using exception handling to track memory allocations of the program code included in the received data set.

Abstract: A global response network collects, analyzes, and distributes “cross-vector” threat-related information between security systems to allow for an intelligent, collaborative, and comprehensive real-time response.

Abstract: This disclosure is related to methods and apparatus used to for preventing malicious content from reaching a destination via a dynamic analysis engine may operate in real-time when packetized data is received. Data packets sent from a source computer may be received and be forwarded to an analysis computer that may monitor actions performed by executable program code included within the set of data packets when making determinations regarding whether the data packet set should be classified as malware. In certain instances all but a last data packet of the data packet set may also be sent to the destination computer while the analysis computer executes and monitors the program code included in the data packet set. In instances when the analysis computer identifies that the data packet set does include malware, the malware may be blocked from reaching the destination computer by not sending the last data packet to the destination computer.

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.
