Say what? I can denial of service attack any brand of network with state level resources... what does Huawei change in that equation?

Do you mean like they could disable the equipment and deny service?

If the COM/SYS layer to the infrastructure is all Huwawei due to no other providers being immediately available for contract, then all of the infrastructure has security issues along the entire chain.

It's implementing the security and 'ownership' of the data along the infrastructure thats at risk. And Huwawei don't have a good track record.

... this isn’t denial of service. ? Also my original question: doesn’t encryption secure the entire chain?
