Systems and methods for application-based interception of SSL/VPN traffic
A method for intercepting, by an agent of a client, communications from the client to be transmitted via a virtual private network connection includes the step of intercepting communications based on identification of an application from which the communication originates. The agent receives information identifying a first application. The agent determines a network communication transmitted by the client originates from the first application and intercepts that communication. The agent transmits the intercepted communication via the virtual private network connection.
1. A method for intercepting application communications for transmission via a virtual private network connection, the method comprising:
(a) receiving, by an agent of a client, an application routing table identifying one or more applications authorized for access via a virtual private network connection established with an device intermediary to the client and at least one server, each of the one or more applications identified via a name of an executable of the corresponding application;
(b) determining, by the agent, whether a first communication from the client is from a first application with a name of an executable identified by the received application routing table; and
(c) transmitting, by the agent based on the determination, the first communication via the virtual private network connection established with the device.
2. The method of claim 1 , comprising transmitting, by the device, the application routing table to the agent.
3. The method of claim 1 , comprising establishing, by the agent, the virtual private network connection with the device.
4. The method of claim 1 , comprising determining, by the agent, that a second communication is from a second application not identified in the application routing table, and allowing the second communication to pass via the client's network stack.
5. The method of claim 1 , comprising determining, by the agent, that a second communication is from a second application not identified in the application routing table, and not intercepting the network communication.
6. The method of claim 1 , comprising determining, by the agent, the name of the executable of the first application via a system level or kernel level call.
7. The method of claim 1 , comprising determining, by the agent, the name of the executable of the first application via an application programming interface.
8. The method of claim 1 , comprising comparing, by the agent, information from the first communication with information in the application routing table.
9. The method of claim 1 , comprising one of granting or denying, by the device, a level of access to the first application based on identification of the first application.
10. The method of claim 1 , comprising transmitting, by the agent, to the device an identification of the first application.
11. A system for intercepting application communications for transmission via a virtual private network connection, the system comprising:
an application routing table identifying one or more applications authorized for access via a virtual private network connection established with an device intermediary to a client and at least one server, each of the first one or more applications identified via a name of an executable of the corresponding application; and
an agent of a client, configured for receiving the application routing table, determining, based on the identification, whether a first communication from the client is from an application with a name of an executable identified by the received application routing table, and transmitting, based on the determination, the first communication via the virtual private network connection established with the device.
12. The system of claim 11 , wherein the application routing table is transmitted by the device to the agent.
13. The system of claim 11 , wherein the agent establishes the virtual private network connection with the device.
14. The system of claim 11 , wherein the agent determines that a second communication is from a second application not identified in the application routing table, and allows the second communication to pass via the client's network stack.
15. The system of claim 11 , wherein the agent determines that a second communication is from a second application not identified in the application routing table, and does not intercept the network communication.
16. The system of claim 11 , wherein the agent determines the name of the executable of the first application via a system level or kernel level call.
17. The system of claim 11 , wherein the agent determines the name of the executable of the first application via an application programming interface.
18. The system of claim 11 , wherein the agent compares information from the first communication with information in the application routing table.
19. The system of claim 11 , wherein the device grants or denies a level of access to the first application based on identification of the first application.
20. The system of claim 11 , wherein the agent transmits to the device an identification of the first application.
