症狀

Computers will be unable to connect using AMT or ISM with non-Transport Layer Security (TLS) network communication after upgrading the computer BIOS with ME firmware version 16.1.25.1991 or later.

Impacted Models:

  • Latitude:
    Latitude 9430, Latitude 9330, Dell Pro 13 Premium, Latitude 7530, Latitude 7430, Latitude 7330, Latitude 7230, Latitude 5531, Latitude 5530, Latitude 5431, Latitude 5430, Latitude 5330.
     
  • OptiPlex:
    OptiPlex 7400, OptiPlex 5400, OptiPlex 7000 MFF, OptiPlex 7000 OEM MT+, OptiPlex 5000 MFF.
     
  • Precision:

  • XPS:
    XPS 17 9720, XPS 15 9520, XPS 13 9320, XPS 13 9315

Impacted CPU:

  • Intel Core 12th Gen CPU (Alder Lake)

原因

Non-TLS network communications may be less secure than TLS network communications because non-TLS communications are not encrypted, while TLS network communications are encrypted.

解析度

Non-TLS Network Communication

Computers that ship with the Intel Core 12th Generation CPUs and Intel Xeon W-3400/W-2400, AMT/ISM no longer support non-TLS network communication.

This is an expected behavior, Intel removed the option to choose non-TLS network communications to help Users provide more secure solutions to Customers.
