Are there anyway to let AMT use dedicated LAN port?

Are there anyway to let mainboard's LAN port only visible to AMT, and disable any access from the operating system just like regular BMC does on server boards? Therefore I can plug AMT port and OS port to different switches to avoid security issues.

Re: Are there anyway to let AMT use dedicated LAN port?

Hello HKong5,

 

Thank you for joining the Intel community

 

This is a pretty interesting question indeed. To be honest I've never heard about this been attempted and the reason might be that AMT is intended for consumer systems (desktops, laptops) which usually contain only 1 ethernet NIC and probably 1 WLAN controller. On servers, it is different because they come at a minimum with 2 NIC ports and sometimes 1 more dedicated for BMC. If this could be done it needed to be at BIOS level probably. I will look for related information and will let you know

Re: Are there anyway to let AMT use dedicated LAN port?

Thank you for your answer! I have a Lenovo TS440 server, which has only 1 onboard LAN port, it hasn't onboard BMC so I have to use AMT to do out band managment.

 

I'm have inserted a 10GbE NIC to PCIe slot for regular communication, and I want onboard NIC invisible to the operating system (make it dedicated for managment just like regular BMC does), therefore if someone hacks into my system, they can't access the managment network.

Hi HKong5,

 

In the OS, you can disable the NIC from it being accessible "in-band".

 

In this scenario, you can disable the AMT NIC (onboard from the OS, disabling in-band access to the NIC) in the OS and use the 10GbE NIC for in-band purposes.

Re: Are there anyway to let AMT use dedicated LAN port?

Thank you, That's I have done. I just to ask there's anyway to force OS don't touch the AMT NIC. Because cracker may have root privilege to re-enable AMT NIC. So I want to find a neat way to disable OS access from firmware layer.

 

Maybe I should create a Point to Point link between firewall and AMT port. And can I disable AMT access from localhost?

Hello HKong5,


If you are planning on using AMT, technically, in his scenario, if someone has root privilege to OS, then they can always enable the AMT NIC in the OS. There is no way that we are aware of the OS to stop something like this. If you just wants it disabled and are not planning on using AMT, just leave it disabled in MEBx.
