In addition, I think that a lot of ISO Layer 1/2 and even L3 gear can be swapped out too without much effort because of open standards (IETF, ISO, etc) that allows for easier mixing and matching.

Whereas a lot of wireless components are more tightly coupled to each other.

Which is why many service providers are talking about Open RAN.

This is the type of content we're here for! Thanks.

Welp. This is what I come to HN for.

good answer. cheers.

"Optical networks like you listed are pretty dumb so aren't nearly as much of a threat"

They can be tapped into still, of course. Doesn't GCHQ copy all the data coming through their fibre lines and run it through computers for analysis?

> They can be tapped into still, of course

Slightly different threat model.

This doesn’t quite make sense... at the end of the day you still put data in one end and it comes out the other... can you not just encrypt?

I’m missing something right?

yes, denial of service attacks.

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?
