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.
