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


Impacted CPU:

  • Intel Core 12th Gen CPU (Alder Lake)

Cause

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.

Resolution

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.
