  • Publication number: 20190132288
    Abstract: Application identification and control in a network device. In one embodiment, a method may include establishing, at a network device, a Virtual Private Network (VPN) tunnel through which all Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) traffic sent from or received at the network device is routed. The method may also include monitoring, at the network device, all TCP and UDP traffic sent from or received at the network device through the VPN tunnel. The method may further include extracting, at the network device, payload data from the monitored TCP and UDP traffic. The method may also include analyzing the extracted payload data to identify applications executing on the network device that sent or received the monitored TCP and UDP traffic. The method may further include taking, at the network device, a security action on the network device based on the identified applications.

  • Patent number: 9781143
    Abstract: A computer-implemented method for detecting near field communication risks may include (1) identifying a mobile device capable of near field communication, (2) identifying an attempted near field communication involving the mobile device, (3) tracking at least one contextual behavior relating to the attempted near field communication; and (4) determining, based at least in part on the contextual behavior, that the attempted near field communication poses a risk to the mobile device. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 9331856
    Abstract: A computer-implemented method for validating digital signatures may include (1) receiving, through a camera of smart glasses, an image of an object, (2) decrypting, using a processor of the smart glasses, a digital signature on the object to obtain a decrypted digital signature, (3) attempting, using the processor of the smart glasses, to validate the object by comparing content of the object with the decrypted digital signature, and (4) outputting a result of the attempt to validate the object from an output component of the smart glasses. Various other methods, systems, and computer-readable media are also disclosed.
