US Patent 9407606 Methods and systems for context-based application firewalls

Context-based application firewall functionality. A user session is initiated with a client device. The user session allows access a remote resource on a server device coupled with the client device over a network. The connection between the client device and the remote resource is through an application firewall. An application firewall context setup is performed with the application firewall in response to the user session. The application firewall context comprises firewall context information to be used during the user session to perform network and application security operations with the application firewall. A response is created to provide information from the remote resource to the client device. The response includes metadata to be used to update the firewall context information. The firewall context information is updated with the application firewall based on the metadata. The response is transmitted to the client device.
