Systems and methods for providing secure access to vulnerable networked devices

1. A computer-implemented method for providing secure access to vulnerable networked devices, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:

identifying a vulnerable networked device connected to a local network;

identifying an application executing on a device connected to the local network as a safe application;

identifying a first portion of local network traffic originating from the safe application and destined for the vulnerable networked device;

tagging the first portion of local network traffic as safe based on the identity of the safe application and the destination of the first portion of local network traffic, wherein the tagging includes marking the first portion of local network traffic with an identifier;

identifying the first portion of local network traffic destined for the vulnerable networked device and that has been tagged as safe;

passing the first portion of local network traffic tagged as safe to the vulnerable networked device; and

performing a security action on a second portion of local network traffic destined for the vulnerable networked device that has not been tagged as safe,

wherein the steps of identifying the application as a safe application, identifying the network traffic originating from the application, and tagging the network traffic as safe are performed external to the device.

2. The computer-implemented method of claim 1 , wherein the identifier corresponds to at least one of:

a virtual local area network tag associated with an ethernet frame; or

an options field within an internet protocol (IP) header.

3. The computer-implemented method of claim 1 , wherein identifying an application as a safe application comprises monitoring network traffic by way of at least one of a filter network driver, a system call, a usability application, establishing a virtual private network, or by acting as a proxy server.

4. The computer-implemented method of claim 1 , further comprising:

identifying a user generating the network traffic destined for the vulnerable networked device; and

wherein tagging the network traffic as safe is further based on the identified user generating the network traffic.

5. The computer-implemented method of claim 1 , further comprising verifying a validity of the tagged network traffic with a public key.

6. The computer-implemented method of claim 1 , further comprising:

prompting an administrator for authorization to tag network traffic originating from a local source and destined for the vulnerable networked device as safe;

receiving authorization from the administrator to tag the network traffic originating from the local source and destined for the vulnerable networked device as safe; and

tagging the network traffic originating from the local source and destined for the vulnerable networked device as safe.

7. The computer-implemented method of claim 6 , further comprising maintaining a record of the authorization from the administrator and tagging future network traffic originating from the local source and destined for the vulnerable networked device without prompting the administrator for further authorization.

8. A system for providing secure access to vulnerable networked devices, the system comprising:

at least one physical processor;

physical memory comprising computer-executable instructions that, when executed by the physical processor, cause the physical processor to:

identify a vulnerable network device connected to a local network;

identify an application executing on a device connected to the local network as a safe application;

identify a first portion of local network traffic originating from the safe application and destined for the vulnerable networked device;

tag the first portion of local network traffic as safe based on the identity of the safe application and the destination of the first portion of local network traffic, wherein the instructions cause the physical processor to mark the first portion of local network traffic with an identifier;

identify the first portion of local network traffic destined for the vulnerable network device and that has been previously tagged as safe;

pass the first portion of local network traffic that has been previously tagged as safe to the vulnerable network device; and

perform a security action on a second portion of local network traffic destined for the vulnerable network device that has not been tagged as safe,

wherein the instructions cause the physical processor to identify the application as a safe application, identify the network traffic originating from the application, and tag the network traffic as safe external to the device.

9. The system of claim 8 , wherein the identifier corresponds to at least one of:

a virtual local area network tag associated with an ethernet frame; or

an options field within an internet protocol (IP) header.

10. The system of claim 8 , wherein the computer-executable instructions further cause the physical processor to:

identify a user generating the network traffic destined for the vulnerable network device; and

wherein tagging the network traffic as safe is further based on the identified user generating the network traffic.

11. The system of claim 8 , wherein the computer-executable instructions further cause the physical processor to:

prompt an administrator for authorization to tag network traffic originating from a local source and destined for the vulnerable network device as safe;

receive authorization from the administrator to tag the network traffic originating from the local source and destined for the vulnerable network device as safe; and

tag the network traffic originating from the local source and destined for the vulnerable network device as safe.

12. The system of claim 11 , wherein the computer-executable instructions further cause the physical processor to:

maintain a record of the authorization from the administrator, and

tag future network traffic originating from the local source and destined for the vulnerable network device without prompting the administrator for further authorization.

13. The system of claim 8 , wherein the computer-executable instructions further cause the physical processor to:

verify a validity of the tagged network traffic with a public key.

14. A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

identify a vulnerable network device connected to a local network;

identify an application executing on a device connected to the local network as a safe application;

identify a first portion of local network traffic originating from the safe application and destined for the vulnerable networked device;

tag the first portion of local network traffic as safe based on the identity of the safe application and the destination of the first portion of local network traffic, wherein the instructions cause the computing device to mark the first portion of local network traffic with an identifier;

identify the first portion of local network traffic destined for the vulnerable network device and that has been previously tagged as safe;

pass the first portion of local network traffic that has been previously tagged as safe to the vulnerable network device; and

perform a security action on a second portion of local network traffic destined for the vulnerable network device that has not been tagged as safe,

wherein the instructions cause the computing device to identify the application as a safe application, identify the network traffic originating from the application, and tag the network traffic as safe external to the device.

15. The non-transitory computer-readable medium of claim 14 , wherein the identifier corresponds to at least one of:

a virtual local area network tag associated with an ethernet frame; or

an options field within an internet protocol (IP) header.
