摘要： An appliance and method for authorizing a level of access of a client to a virtual private network connection, based on a client-side attribute includes the step of establishing, by an appliance, a control connection with a client upon receiving a client request to establish a virtual private network connection with a network. The appliance transmits, via the control connection, a request to the client to evaluate at least one clause of a security string, the at least one clause including an expression associated with a client-side attribute. The client transmits, via the control connection, a response to the appliance comprising a result of evaluating the at least one clause by the client. The appliance assigns the client to an authorization group based on the result of evaluation of the at least one clause.

摘要： A method for allowing or denying, by an appliance, access to a resource by an application on a client via a virtual private network connection includes basing the decision to allow or deny access on identification of the application. The appliance intercepts a request from an application on a client on a first network to access via a virtual private network connection a resource on a second network. The appliance identifies the application and associates with the intercepted request an authorization policy based on the identity of the application. The appliance determines, using the authorization policy and the identity of the application, to either allow or deny access by the application to the resource.

摘要： A method for intercepting communication of a client to a destination on a virtual private network includes an agent executing on the client that intercepts a network communication of the client. The agent provides a virtual private network connection from a first network to a second network. The decision to intercept is based on a network destination description or an identification of an application authorized to be accessed via the virtual private network. In one case, the agent determines that a destination specified by the intercepted communication corresponds to a network identifier and a port of a network destination description of an application on the second network authorized for access via the virtual private network. In response to this determination, the agent transmits the intercepted communication.

摘要： The present invention relates to systems and methods to identify a level of access for a resource being accessed via a secure socket layer virtual private network (SSL VPN) connection to a network, and to control the action on the resource based on the identified level of access. The appliance described herein provides intelligent secure access and action control to resources based on a sense and respond mechanism. When a user requests access to a resource via the SSL VPN connection of the appliance, the appliance obtains information about the client to determine the user access scenario—the location, device, connection and identify of the user or client. Based on the collected information, the appliance responds to the detected user scenario by identifying a level of access to the resource for the user/client, such as rights to view, print, edit or save a document, Based on the identified level of access, the appliance controls the actions performs on the resource by various techniques described herein so that the user can only perform the allowed action n accordance with the level of access. As such, the present invention allows organization to control and provide the appropriate level of access to valuable, confidential or business critical information accessed remotely or via a pubic network while protecting such information by controlling the types of actions performed or allowed to be performed remotely on the information.
