Storbritannien vil ikke tillade Huawei at stå for centrale dele af deres 5G-netværk

And yes, we assumed in the decision process that the Chinese state:
* could compel anyone in China to do anything (which they’ve now codified in their National Intelligence Law)
* would carry out cyber attacks against the UK at some point (which we’ve recently publicly confirmed)

The mitigation formed a set of principles that BT still follow to this day, although they’ve evolved a bit as technology matures. They include things like:
...
* keep more risky vendors out of sensitive functions (like some of those in the core and anything to do with lawful intercept)
...
This was going fine until about 2008, when other operators wanted to use Huawei. It made no sense to try to get every operator to replicate the work BT had done, so we came up with a different model, which expanded the principles a little and required the establishment of the Huawei Cyber Security Evaluation Centre (HCSEC). HCSEC is a common security team created to analyse and give information to operators to help them do their risk management well when using Huawei kit.
...
That model has worked pretty well for the past 8 years. It’s not perfect; not every operator that uses Huawei kit follows the principles or uses HCSEC to get information, but most of the big ones do.

Last year’s Oversight Board report raised some serious concerns about Huawei’s software engineering and cyber security capabilities. This year’s report will expand on that but, because of this mitigation model, the UK operators that use HCSEC have unparalleled information to help them manage the risk of using Huawei kit. However, this long-term risk management of Huawei’s poor security and engineering takes sustained effort over the life of the system, and is only possible if supported by strong architecture and operational management. Management of the national security risks takes sustained effort as well.

Britain will block Huawei from all core parts of the 5G network and access to non-core parts would be restricted
