How to enable for vPro/AMT computers mutual authentication using certificates.

In May 2017 Intel publicly confirmed the vulnerability in own firmware for vPro/AMT.

To download and patch such computers from Dell use links inside the PDF file from following link.

But as i mentioned in my linkedin post it’s possible to protect even noname computers (without updated BIOS) with compromised ME firmware — implementing SSL/TLS certificates for mutual authentication. In this post i will show how it can be done.

Rufus as an alternative for free Microsoft Windows 7 USB DVD download tool

Microsoft Windows 7 USB DVD download tool is very capricious, long time is not updated, doesn’t work in many cases (can after spent long time to copy 2-4gb, only in the end of process suddenly cast error that couldn’t create boot records; or doesn’t work on other version of windows and so on).

How to create handy boot USB toolbox

To have for each tool CD/DVD/USB flash disk is too inconvenient, so let’s combine on one USB flash disk all of them.

Some recommendations for windows installers.

    1. if you want to install any version of Windows on large disk (bigger than 2TB) start your PC from UEFI, not from conventional BIOS boot. Otherwise you will be able after installation to use only 2TB from for example 3 or 4TB hdd.
    2. sometimes previous OEM repair service partitions, or linux/unix partitions cannot be removed from HDD by windows GUI, in this case just do following (NEVER DO IT ON HDD WITH DATA, after “clean” command whole disk (all partitions) will be erased ! ):
      list disk
      select disk 0

      (if you install fresh windows – during booting

How manually enable Let’s encrypt SSL for Windows IIS server.

Let’s Encrypt free certificates are very useful for Microsoft web servers, MS Dynamics Nav web client access, Exchange and Lync/Skype for business external accesses and so on (better to use it with windows ACME clients for auto prolongation of certificate)
