Abstract: A handshake procedure to establish a first connection between a client and a server is monitored at an intermediate network device. A request message sent to the server from the client is received at the intermediate network device. The request message includes parameters defining a manner of receiving information from the server. The parameters defining the manner of receiving information from the server are modified to produce modified parameters. A redirect message is sent from the intermediate network device to the client to induce or cause the client to establish a second connection with the server based upon the modified parameters, wherein the redirect message contains the modified parameters.

Abstract: Techniques are presented herein for a proxy device to verify that the server name listed in a connection request message is the name of the server at the IP address listed in the connection request message. The proxy device obtains a domain name server query sent by a client to a domain name server and then obtains a domain name server result that is sent by the domain name server. The proxy device may cache the data of the domain name server result. The proxy device may obtain a connection request message sent by the client seeking a connection with a server, and then compare the connection request message to the cached domain name server result. Finally, the proxy device may apply one or more policies to the connection request message based on the comparison between the connection request message and the domain name server result.

Abstract: A network security device (NSD) is connected between a network and an endpoint device configured to host a client application. The client application communicates with the network through the network security device using a request-response protocol. The NSD receives from the client application a request destined for the network and that seeks a response from the network. The request has a context header including context information about the client application. The NSD determines whether the client application or a file accessed thereby has a suspicious nature based on the context information. If it is determined that the client application or the file accessed thereby has a suspicious nature, the NSD blocks the request from the network, and sends to the client application a response indicating the block.

Abstract: A secure VPN connection is provided based on user identify and a hardware identifier. A client application may initiate the VPN connection. A client device user may provide identification information to the application, which then sends a VPN connection request to a remote VPN gateway. The VPN gateway may require an equipment identifier to establish the secure VPN gateway. If the hardware ID is registered, the secure VPN connection is established. If the hardware ID is not registered with the VPN gateway, the connection may be denied. In some instances, a connection may be established with an unregistered equipment ID based on settings at the VPN gateway.
