Tiger Lake Intel’s Anti-Malware Hardware Added CPUs

The latest hardware-based security feature, Control-Flow Enforcement Technology (CET) will be used by Intel in its future Tiger Lake mobile CPUs. The vice president of Intel’s Client Computing Group and general manager of Security Strategies and Initiatives, Tom Garrison said, It was something that needed a company like Intel to stand up and deliver a hardware-based solution, but also to do it at scale with our partners and deliver it throughout the ecosystem.


Details: Tiger Lake CPUs


The Intel described CET in 2016, and work on CET for four years collaborating with Microsoft, and very soon their effort will be first seen in the laptops of 10-nanometer Tiger Lake CPUs. The CET based CPUs will able to work with only the operating system which will be capable support that, that is not a matter of stress because Microsoft has previously added support for CET in Windows 10 version 2004.

Tom Garrison said the performance impact of CET is very minimal. He further said, The idea here is that if they don’t match it, it’s because somebody manipulated the address, and it flags that as an error, and it’s detected.

Garrison also said, The compiler that they use will be enabled with CET. That’s where most of the work is.

There are two leading abilities included in the CET, Indirect Branch Tracking, and Shadow Stack.

The Indirect Branch Tracking, secure against Jump based programing. This not only prevents attackers thus they can not jump to an arbitrary part of the code, but also it forces them to end the branch of an address.  It assure the attacker can not modify code into an inadvertent process.

The Shadow Stack authorized at the Operating system level and work as an exact duplicate of the return addresses of an application. On the condition of if a return address is modified and does not match its exact duplicate copy in the shadow stack then the Control-Flow Enforcement Technology (CET) will protect the code from performing, and also throwback a failure.

The expected released date of Intel’s Tiger Lake CPUs is in 2021.
