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.

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.

Verification of server name in a proxy device for connection requests made using domain names

In one embodiment, a method includes establishing at a security device, a secure session for transmitting data between a client device and an end host, receiving decrypted data at the security device from the client device, inspecting the decrypted data at the security device, encrypting the decrypted data at the security device, and transmitting encrypted data to the end host. Decryption at the client device is offloaded from the security device to distribute decryption and encryption processes between the client device and the security device. An apparatus and logic are also disclosed herein.

Method and apparatus for distributing encryption and decryption processes between network devices

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.

Context sharing between endpoint device and network security device using in-band communications

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.

Mobile device identify factor for access control policies

Integrity checking a remote client includes generating integrity services configured to perform integrity checks on the client when executed thereon, and downloading a set of the generated services to the client. The integrity checking also includes receiving respective integrity check results from the downloaded services and performing respective integrity tests on each downloaded service based in part on the integrity check results received from that service. The integrity checking further includes replacing the set of downloaded services with a new set of services that perform same integrity tests as the replaced set of downloaded services if any downloaded service fails the respective integrity test performed thereon.
