  • Social media login and interaction management
    Patent number: 10057271
    Abstract: A hardware or software firewall may be installed within a private network. The firewall may intercept a first set of login credentials entered into a login interface of a social media platform. The firewall then checks that the first set of login credentials are correct against a first set of reference login credentials stored in a firewall memory, and sends a second set of login credentials to the login interface of the social media platform. This allows business employees to access a corporate social media profile from a private network but not outside the private network. The firewall can also limit social media interactions using the firewall by limiting the other profiles that a user's profile can interact with (e.g., using a whitelist, blacklist, or reputation score), by limiting communication types (e.g., using a whitelist or blacklist), by imposing firewall policies, or some combination thereof.

  • Statistical message classifier
    Patent number: 10044656
    Abstract: A system and method are disclosed for improving a statistical message classifier. A message may be tested with a machine classifier, wherein the machine classifier is capable of making a classification on the message. In the event the message is classifiable by the machine classifier, the statistical message classifier is updated according to the reliable classification made by the machine classifier. The message may also be tested with a first classifier. In the event that the message is not classifiable by the first classifier, it is tested with a second classifier, wherein the second classifier is capable of making a second classification. In the event that the message is classifiable by the second classifier, the statistical message classifier is updated according to the second classification.

  • Virtual private network dead peer detection
    Patent number: 10044585
    Abstract: Methods and systems are provided for detecting dead tunnels associated with a VPN. An indicator of a tunnel capability, for example, a DPD vendor ID, is received from a peer through a VPN connection. The tunnel capability is associated with one or more phase II tunnels associated with the VPN. Traffic generated by the peer is detected, and if traffic is detected at a tunnel, the tunnel is presumed to be alive. When no traffic is detected in a tunnel, a DPD packet exchange with the tunnel is initiated. A determination is made, based on the packet exchange, whether the tunnel is alive.

  • Notification for reassembly-free file scanning
    Patent number: 10021121
    Abstract: Techniques for notification of reassembly-free file scanning are described herein. According to one embodiment, a first request for accessing a document provided by a remote node is received from a client. In response to the first request, it is determined whether a second request previously for accessing the document of the remote node indicates that the requested document from the remote node contains offensive data. If the requested document contains offensive data, a message is returned to the client, without accessing the requested document of the remote node, indicating that the requested document is not delivered to the client.

  • Unified source user checking of TCP data packets for network data leakage prevention
    Patent number: 10015145
    Abstract: Systems and methods are directed towards network data leakage prevention (DLP). More specifically, the systems and methods are directed towards using TCP (Transmission Control Protocol) data packets in conjunction with the DLP monitor. The network DLP utilizes TCP data packets to carry source user identity. With the source user identity, the DLP monitor can determine if sensitive data can be transmitted based on the provided user information and corresponding DLP policies for each user. Furthermore, the DLP monitor can determine if sensitive data can also be transmitted for particular users in situations where multiple users share the same IP address.

  • Rule-based routing to resources through a network
    Patent number: 10003576
    Abstract: Techniques for determining which resource access requests are handled locally at a remote computer, and which resource access requests are routed or “redirected” through a virtual private network. One or more routing or “redirection” rules are downloaded from a redirection rule server to a remote computer. When the node of the virtual private network running on the remote computer receives a resource access request, it compares the identified resource with the rules. Based upon how the identified resource matches one or more rules, the node will determine whether the resource access request is redirected through the virtual private network or handled locally (e.g., retrieved locally from another network). A single set of redirection rules can be distributed to and employed by a variety of different virtual private network communication techniques.

  • Dynamic bypass of TLS connections matching exclusion list in DPI-SSL in a NAT deployment
    Patent number: 9998425
    Abstract: The present invention provides the initiation of a transport layer security (TLS) session between a client device and a server using a firewall without interruption. The present invention holds a TLS hello message received from the client device until after the server has been validated. A firewall consistent with the present invention does not interrupt a transport layer control (TCP) connection that was established between the client device and the firewall before the TLS hello message was received by the firewall.

  • Transparent deferred spooling store and forward based on standard network system and client interface
    Patent number: 9917882
    Abstract: A transparent batch file transfer is provided from a client to a server via a batch pool system. The batch pool system may be implemented by a proxy file server which is used to receive the file transfer from the client device and free the client device as soon as possible. The file transfer to an intended remote server is carried out by a batch transfer system at the proxy file server. The user of the client machine may then use their device to perform other tasks while the file transfer is completed by the proxy file server batch transfer system. The file transfer is coordinated by a background transfer module that is integrated with file system protocols. Hence, there is no new system or software for a user of the client to learn or operate.

  • Printed document control with verified unique watermarks
    Patent number: 9917979
    Abstract: Systems and methods are directed towards generating a verified unique watermark. More specifically, the systems and methods are directed towards generating a watermark that is as long as possible without any repetition. Such watermarks are possible by selecting characteristics of the watermark and methods for producing the watermarks (e.g., dandy rollers). By producing longer unique watermarks, users would be capable of generating longer rolls of paper whereby more sheets can be produced that each possesses a unique watermark. With the unique watermark, users can identify what information is printed on each sheet as well as authenticate the contents of each individual sheet.

  • Secure neighbor discovery (SEND) using pre-shared key
    Patent number: 9912484
    Abstract: An extension is provided to the SEND protocol without requiring a CGA or third party trust anchor. A shared key is provided to both a sender and receiver of a neighbor discovery (ND) message. A digital signature option is contained in the ND message. A digital signature field is determined by the algorithm field in the option. When the ND message is received, the receiver may verify the digital signature field using the pre-shared key according to the algorithm field. If the ND message passes verification, the receiver may process the message.
