System, method, and computer program product for receiving security content utilizing a serial over LAN connection
View Patent ↗A system, method, and computer program product are provided for receiving security content utilizing a serial over LAN connection. In use, an unsuccessful attempt to connect to a network for accessing security content at a remote second device is indicated by a first device, where the unsuccessful attempt results from a malfunction at the first device. Further, the security content is received at the first device utilizing a serial over local area network (LAN) connection established with the remote second device, based on the indication.
1. A non-transitory computer readable medium, comprising instructions stored thereon to cause one or more processors to:
detect, at a central manager device, an indication of a failure of a client device to obtain security content from a security content provider system over a first computer network, the failure caused by a software malfunction at the client device; and
instruct the security content provider system to:
establish a serial over local area network connection to the client device in response to the detection by the central manager device of the indication of the failure of the client device to obtain the security content from the security content provider system over the first computer network; and
transmit the security content to the client device utilizing the serial over local area network connection.
2. The non-transitory computer readable medium of claim 1 , wherein the security content includes signatures for use in detecting malware.
3. The non-transitory computer readable medium of claim 1 , wherein the central manager device detects the indication of the failure at the client device at least in part by reading a flag at the client device.
4. The non-transitory computer readable medium of claim 3 , wherein reading the flag comprises obtaining the flag from a storage area of active management technology provided by a processor of the client device.
5. The non-transitory computer readable medium of claim 1 , wherein establishing the serial over local area network connection comprises establishing a connection over a second network.
6. The non-transitory computer readable medium of claim 1 , wherein the software malfunction includes a network driver malfunction.
7. The non-transitory computer readable medium of claim 1 , wherein the software malfunction includes non-compliance with a security policy requiring compliance to connect to the first computer network.
8. The non-transitory computer readable medium of claim 1 , wherein the serial over local area network connection comprises a connection to a virtual serial port of the client device.
9. The non-transitory computer readable medium of claim 1 , wherein the serial over local area network connection includes a connection by the security content provider system to an active management technology BIOS of the client device, wherein the active management technology BIOS is able to bypass an operating system network communication protocol while the client device receives the security content.
10. A non-transitory computer readable medium, comprising instructions stored thereon to cause one or more processors to:
identify, at a client device, a failure of an attempt to connect to a first computer network to obtain security content from a security content provider system, the failure caused by a software malfunction at the client device;
provide to a central manager device an indication of the failure to obtain the security content in response to the failure to obtain the security content over the first computer network from the security content provider system; and
receive, at the client device, the security content from the security content provider system utilizing a serial over local area network connection.
11. The non-transitory computer readable medium of claim 10 , wherein the instructions to provide an indication of the failure comprise instructions to send an error status event over a second computer network.
12. The non-transitory computer readable medium of claim 10 , wherein the instructions to provide an indication of the failure comprise instructions to set a flag in a storage area of active management technology provided by a processor of the client device.
13. The non-transitory computer readable medium of claim 12 , wherein the storage area is readable by the central manager device to allow the central manager device to detect the flag.
14. The non-transitory computer readable medium of claim 12 , further comprising instructions stored thereon to cause one or more processors to:
clear the flag upon receipt of the security content.
15. The non-transitory computer readable medium of claim 10 , wherein the serial over local area network connection comprises a connection to a virtual serial port of the client device.
16. The non-transitory computer readable medium of claim 10 , further comprising instructions to cause one or more processors to:
install the security content on the client device.
17. A system, comprising:
a central manager device;
a client device adapted to provide to the central manager an indication of a failure of an attempt to connect to a first computer network to obtain security content, the failure caused by a software malfunction at the client device; and
a security content provider adapted to establish a serial over local area network connection with the client device over a second computer network in response to instructions from the central manager device responsive to a detection by the central manager device of the indication, the serial over local area network connection utilized to send the security content between the security content provider and the client device.
18. The system of claim 17 , wherein the serial over local area network connection comprises a connection to a virtual serial port of the client device.
