  • Patent number: 9264429
    Abstract: The present invention provides a system and method of managing traffic traversing an intermediary based on a result of end point auditing. An authentication virtual server of an intermediary may determine a result of an end point analysis scan of a client. Responsive to the determination, the traffic management virtual server can obtain the result from the authentication virtual server. Further, the traffic management virtual server may apply the result in one or more traffic management policies to manage network traffic of a connection of the client traversing the intermediary. In some embodiments, the authentication virtual server may receive one or more expressions evaluated by the client. The one or more expressions identifies one or more attributes of the client. The traffic management virtual server can also determine a type of compression or encryption for the connection based on applying the one or more traffic management policies using the result.

  • Patent number: 8909756
    Abstract: The present application is directed towards systems and methods for managing server initiated connections via a multi-core system that provides VPN access between clients and servers. The solution described herein provides a mechanism by which server and client communications via the multi-core system for a server initiated connection may be received on different cores and for the system to manage these communications across different cores to provide an end-to-end connectivity between the client and the server.

  • Patent number: 8782755
    Abstract: The present invention provides a system and method for dynamically selecting an authentication virtual server from a plurality of authentication virtual servers. A traffic management virtual server may determine from a request received from a client to access content of a server that the client has not been authenticated. The traffic management virtual server can identify a policy for selecting an authentication virtual server to provide authentication of the client. Responsive to the identification, the traffic management virtual server can select, via the policy, an authentication virtual server of the plurality of authentication virtual servers to authenticate the client. Responsive to the request, the traffic management virtual server may transmit a response to the client The response includes an instruction to redirect to the selected authentication virtual server.

  • Patent number: 8667575
    Abstract: A method for propagating authentication session information to a plurality of cores of a multi-core device includes establishing, by an authentication virtual server executing on a first core of a device intermediary to at least one client and server, a session for a user, the authentication virtual server authenticating the session. A traffic management virtual server executes on a second core of device, and receives a request to access a server via the session. The traffic management virtual server may identify, responsive to a determination that the session is not stored by the second core, from an identifier of the session that the first core established the session. The second core may send to the first core a request for data for the session identified by the identifier. The second core may receive from the first core a response to the second request identifying whether the session is valid.

    Abstract: The present invention provides a system and method for authentication of network traffic managed by a traffic management virtual server. A traffic management virtual server may determine that a client has not been authenticated from a request of the client to access a server. Responsive to the request, the traffic management virtual server may transmit a response to the client with instructions to redirect to an authentication virtual server. The authentication virtual server may receive a second request from the client. The authentication virtual server may then authenticate credentials received from the client and establish an authentication session for the client. Further, the authentication virtual server may transmit a second response to redirect the client to the traffic management virtual server. The second response identifies the authentication session. The traffic management virtual server then receives a request from the client with an identifier to the authentication session.
