In one embodiment, a controller features a first data store, a second data store and route determination logic. The first data store is configured to store current routing information from a source transit gateway within at least a first transit cloud network to a destination transit gateway within at least a second transit cloud network of the cloud network. Each of the source transit gateway and the destination transit gateway being one of a plurality of transit gateways associated with the cloud network. The second data store is configured to store alternative routing information between the source transit gateway and the destination transit gateway. The route determination logic is configured to (i) conduct analytics on all available route paths for a message intended to be sent from the source transit gateway to the destination transit gateway and (ii) select a best route path for the message.

Multi-cloud active mesh network system and method

According to one embodiment, a network system features a first virtual private cloud (VPC) network and a second VPC network. The first VPC network includes a first plurality of gateways. Each gateway of the first plurality of gateways is in communications with other gateways. Similarly, a second VPC network includes a second plurality of gateways. Each of the second plurality of gateways is communicatively coupled to the each of the first plurality of gateways to support data exchanges between resources deployed in different public cloud networks.

According to one embodiment, a network system features a first virtual private cloud (VPC) network and a second VPC network. The first VPC network includes a first plurality of gateways. Each gateway of the first plurality of gateways is in communications with other gateways of the first plurality of gateways in accordance with a first tunnel protocol. Similarly, a second VPC network includes a second plurality of gateways. Each of the second plurality of gateways is communicatively coupled to the each of the first plurality of gateways in accordance with a second security protocol to provide redundant routing.

Active mesh network system and method

Techniques are provided for obtaining first and second digital certificates from a certificate authority database for establishing a secure exchange between network devices. The first digital certificate contains identity information of a first network device, and the second digital certificate contains classification information of the first network device. In one embodiment, a secure key exchange is initiated with the second network device, and the first and second digital certificates are transmitted as a part of the secure key exchange to the second network device. In another embodiment, the first and second digital certificates are received by an intermediate network device. The first digital certificate is encrypted and is not evaluated by the intermediate network device. The second digital certificate is evaluated for classification information of the first network device. Source information associated with the first network device is stored, and encrypted traffic is processed between the network devices.

Techniques to classify virtual private network traffic based on identity

A method is disclosed for obtaining certificate revocation information from a server, obtaining from a client a request for a revocation status of a certificate and notifying the client when the certificate identified in the client request has been revoked. The method may be performed by a networking device that is separate from the server and the client.

Determining certificate revocation status

In one embodiment, an apparatus comprises logic for detecting stolen authentication cookie attacks. A first transport connection is established between a client and a gateway server, where the first transport connection is authenticated by the gateway server. A first authentication cookie is associated with a client session, between the client and the gateway server, that includes the first transport connection. A second transport connection is established at the gateway server. A request is received over the second transport connection. The request includes the first authentication cookie to associate the second transport connection with the client session. A second authentication cookie is generated for the client session and is returned over the second transport connection. Thereafter, a determination is made whether the second authentication cookie is received over the first transport connection. An attack is detected when the second authentication cookie is not received over the first transport connection.
