Abstract

In one embodiment, a router includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the router to perform operations including receiving software-defined networking in a wide area network (SD-WAN) policies from a component of an SD-WAN network. The operations also include establishing a session with a mobile device and receiving information associated with the mobile device in response to establishing the session with the mobile device. The operations further include filtering the SD-WAN policies based on the information associated with the mobile device to generate SD-WAN device-specific policies and communicating the SD-WAN device-specific policies to the mobile device.

First claim

What is claimed is:

1. An apparatus, comprising:
one or more processors; and
one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause the apparatus to perform operations comprising:
receiving software-defined networking in a wide area network (SD-WAN) policies from a component of an SD-WAN network;
establishing a session with a mobile device;
receiving information associated with the mobile device in response to establishing the session with the mobile device, wherein the information associated with the mobile device comprises device posture information comprising a hostname and an identification of an operating system;
filtering the SD-WAN policies based on the information associated with the mobile device to generate SD-WAN device-specific policies; and
communicating the SD-WAN device-specific policies to the mobile device.

2. The apparatus of claim 1 , the operations further comprising:
receiving updated SD-WAN policies from the component of the SD-WAN network;
filtering the updated SD-WAN policies based on the information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

3. The apparatus of claim 1 , the operations further comprising:
receiving updated information associated with the mobile device;
filtering the SD-WAN policies based on the updated information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

4. The apparatus of claim 1 , wherein the SD-WAN policies comprise at least one of the following types of policies:
access policies;
segmentation-based policies;
flow classification policies; or
path selection policies.

5. The apparatus of claim 1 , wherein the information associated with the mobile device further comprises security posture information.

6. The apparatus of claim 1 , wherein:
the apparatus is a virtual routing and forwarding (VRF) enterprise Internet Protocol Security (IPsec) gateway; and
the component of the SD-WAN network is a VRF SD-WAN edge router.

7. The apparatus of claim 1 , wherein:
the session between the mobile device and the apparatus is a Virtual Private Network (VPN) session; and
the apparatus is a VRF enterprise Secure Sockets Layer/Transport Layer Security SSL/DTLS gateway.

8. A method, comprising:
receiving software-defined networking in a wide area network (SD-WAN) policies from a component of an SD-WAN network;
establishing a session with a mobile device;
receiving information associated with the mobile device in response to establishing the session with the mobile device, wherein the information associated with the mobile device comprises device posture information comprising a hostname and an identification of an operating system;
filtering the SD-WAN policies based on the information associated with the mobile device to generate SD-WAN device-specific policies; and
communicating the SD-WAN device-specific policies to the mobile device.

9. The method of claim 8 , further comprising:
receiving updated SD-WAN policies from the component of the SD-WAN network;
filtering the updated SD-WAN policies based on the information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

10. The method of claim 8 , further comprising:
receiving updated information associated with the mobile device;
filtering the SD-WAN policies based on the updated information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

11. The method of claim 8 , wherein the SD-WAN policies comprise at least one of the following types of policies:
access policies;
segmentation-based policies;
flow classification policies; or
path selection policies.

12. The method of claim 8 , wherein the information associated with the mobile device further comprises security posture information.

13. The method of claim 8 , wherein:
the SD-WAN policies are received by a virtual routing and forwarding (VRF) enterprise Internet Protocol Security (IPsec) gateway; and
the component of the SD-WAN network is a VRF SD-WAN edge router.

14. The method of claim 8 , wherein:
the session is a Virtual Private Network (VPN) session; and
the SD-WAN policies are received by a VRF enterprise Secure Sockets Layer/Transport Layer Security SSL/DTLS gateway.

15. One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:
receiving software-defined networking in a wide area network (SD-WAN) policies from a component of an SD-WAN network;
establishing a session with a mobile device;
receiving information associated with the mobile device in response to establishing the session with the mobile device, wherein the information associated with the mobile device comprises device posture information comprising a hostname and an identification of an operating system;
filtering the SD-WAN policies based on the information associated with the mobile device to generate SD-WAN device-specific policies; and
communicating the SD-WAN device-specific policies to the mobile device.

16. The one or more computer-readable storage media of claim 15 , the operations further comprising:
receiving updated SD-WAN policies from the component of the SD-WAN network;
filtering the updated SD-WAN policies based on the information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

17. The one or more computer-readable storage media of claim 15 , the operations further comprising:
receiving updated information associated with the mobile device;
filtering the SD-WAN policies based on the updated information associated with the mobile device to generate updated SD-WAN device-specific policies; and
communicating the updated SD-WAN device-specific policies to the mobile device.

18. The one or more computer-readable storage media of claim 15 , wherein the SD-WAN policies comprise at least one of the following types of policies:
access policies;
segmentation-based policies;
flow classification policies; or
path selection policies.

19. The one or more computer-readable storage media of claim 15 , wherein the information associated with the mobile device further comprises security posture information.

20. The one or more computer-readable storage media of claim 15 , wherein:
the SD-WAN policies are received by a virtual routing and forwarding (VRF) enterprise Internet Protocol Security (IPsec) gateway; and
