Abstract

A network device comprises one or more processors coupled to a memory, and a dynamic services module configured for execution by the one or more processors to receive, from a client device, a service request specifying a service. The dynamic service module is further configured for execution by the one or more processors to, in response to obtaining a negative indication for the service, send a representation of the service request to a honeypot to cause the honeypot to offer the service to the client device.

First claim

What is claimed is:

1. A method comprising:
receiving, by a network device from a client device, a service request to receive a service indicated in the service request from a server indicated in the service request, wherein the service request specifies an address for the server indicated in the service request, and wherein the address is not associated with the network device; and
by the network device and in response to obtaining a negative indication for the service that indicates the server indicated in the service request does not offer the service, sending a representation of the service request to a honeypot to cause the honeypot to offer the service to the client device, wherein the negative indication for the service comprises an expiry of a timer for the service response without the network device having received a positive indication for the service from the server indicated in the service request.

2. The method of claim 1 ,
wherein the service request includes address for the server indicated in the service request comprises a layer 3 destination address to indicate the server indicated in the service request, and
wherein no server of a network that includes the network device has a layer 3 address that is the layer 3 destination address.

3. The method of claim 1 , further comprising:
generating, by the network device in response to obtaining a negative indication for the service that indicates the server indicated in the service request does not offer the service, a positive indication for the service; and
sending, by the network device to the client device, the positive indication for the service.

4. The method of claim 1 , further comprising:
proxying, by the network device, a service session for the service between the honeypot and the client device to offer the service to the client device.

5. The method of claim 1 ,
wherein the service request comprises a first service request, and
wherein the negative indication for the service comprises a negative indication for the first service request, the method further comprising:
receiving, by the network device, a second service request specifying the service; and
by the network device and in response to obtaining the negative indication for the first service request, sending a representation of the second service request to the honeypot to cause the honeypot to offer the service to the client device without obtaining a negative indication for the second service request.

6. The method of claim 1 ,
wherein the network device comprises a security appliance, and
wherein the service request includes a layer 3 destination address for the server indicated in the service request, wherein the server is located within a network protected by the security appliance.

7. The method of claim 1 ,
wherein the network device comprises a security appliance, and
wherein the client device is located within a network protected by the security appliance.

8. The method of claim 1 , wherein the representation of the service request causes the honeypot to dynamically offer the service to imitate the service to the client device as if the service were provided by the server indicated in the service request.

9. A method comprising:
receiving, by a network device, a probe from a client device;
receiving, by the network device from the client device and after receiving the probe, a service request to receive a service indicated in the service request from a server indicated in the service request;
sending, by the network device in response to obtaining a negative indication for the service that indicates the server indicated in the service request does not offer the service and determining the network device previously received the probe from the client device, a representation of the service request to a honeypot to cause the honeypot to offer the service to the client device.

10. The method of claim 9 , wherein the probe specifies a destination address that is not associated with the network device, the method further comprising:
by the network device and in response to receiving the probe from the client device, generating a probe response indicating that the destination address is associated with the server indicated in the service request; and
sending, by the network device, the probe response to the client device.

11. The method of claim 9 ,
wherein the probe comprises an Internet Control Message Protocol echo request, and
wherein the probe response comprises an Internet Control Message Protocol echo response.

12. The method of claim 9 ,
wherein the probe specifies a destination address that is not associated with the network device, and
wherein the destination address is not associated with any server of a network that includes the network device.

13. The method of claim 9 ,
wherein the service request specifies an address for the server indicated in the service request, wherein the address is not associated with the network device, and
wherein obtaining a negative indication for the service comprises receiving, by the network device, a negative service response for the service from the server indicated in the service request.

14. The method of claim 13 ,
wherein the service request comprises a Transmission Control Protocol SYN packet, and
wherein the negative service response comprises a Transmission Control Protocol SYN RST packet.

15. The method of claim 9 , wherein the negative indication for the service comprises an expiry of a timer for the service response without the network device having received a positive indication for the service from the server indicated in the service request.

16. A non-transitory computer-readable storage medium comprising instructions stored thereon that, when executed, configure one or more processors to:
receive, by a network device from a client device, a service request to receive a service indicated in the service request from a server indicated in the service request, wherein the service request specifies an address for the server indicated in the service request, and wherein the address is not associated with the network device; and
by the network device and in response to obtaining a negative indication for the service that indicates the server indicated in the service request does not offer the service, send a representation of the service request to a honeypot to cause the honeypot to offer the service to the client device, wherein the negative indication for the service comprises an expiry of a timer for the service response without the network device having received a positive indication for the service from the server indicated in the service request.

17. A network device comprising:
one or more processors coupled to a memory;
a dynamic services module configured for execution by the one or more processors to:
receive, from a client device, a service request to receive a service indicated in the service request from a server indicated in the service request, wherein the service request specifies an address for the server indicated in the service request, and wherein the address is not associated with the network device; and
in response to obtaining a negative indication for the service that indicates the server indicated in the service request does not offer the service, send a representation of the service request to a honeypot to cause the honeypot to offer the service to the client device, wherein the negative indication for the service comprises an expiry of a timer for the service response without the network device having received a pos
