Re: Catch-22
Denial-of-service attacks are definite threats. We don't know yet what happened at CenturyLink. but it appears - vendor claims to the contrary - that cascading system-wide failures are still a thing, even outside of BGP.

It is indeed easy to tap a fiber. Scratch off a little cladding and bend and hope that nobody notices the added loss. That's not the same thing as compromising hardware and/or software to create a covert monitor and side-channel -- and keeping them covert.

Re: Catch-22
 

How to tap and what you would do with it might be interesting.  Let's say we go to these networked self-driving cars....suddenly we have no wireless internet and poof all auto travel shut down in the US.

Why a particular spot?  Because assume ALL equipment is bugged (just the Cisco and Juniper gear is bugged by the CIA).  

How to do optical?  I worked on some stuff where we split small portions of the light for monitoring....

Re: Catch-22
No it was not debunked.  It was denied.  There are US Gov documents that show that it happened.

Re: Catch-22
Wasn't the hardware backdoor story debunked?

It turns out that Nokia has a significant presence in China, mostly China Mobile.

As a thought experiment, consider a WDM/OTN core transport switch (like a Huawei Optix OSN-9800). How would you mount an eavesdropping attack on such a beast and keep it hidden?

Another thought experiment: an OLT/edge router serving a rural community (with no defense-related presence).  Plenty of ways to get into the data path, but no valuable assets. Why would they bother?

Re: Catch-22
@Duh!,

Do you remember the scandal that was revealed this fall when it was reported that some servers that were made in China had hardware backdoors built into them?

Spies spy.  That is what they do.  No matter what country they are in.  China has heavily invested in comm equipment so that it no longer imports gear from the US.  Comm equipment is a modern form of weaponry.

Catch-22
I'm skeptical. It's fair to accept at face value that these companies will do the bidding of the Chinese government It's more difficult to believe that ALL classes of Chinese-made equipment, even in the remotest, most consumer focused corners of the network, could present a meaningful threat to national security. Edge/aggregation routers, maybe. OLTs or optical transponders? Please explain.

Here's the catch:  The deep-dive analysis (plus any intel) is undoubtedly classified with classifications that are classified. There isn't even an unclassified summary. So, they say: "trust us".

Of course, it's a complete coincidence that the US govermment is fomenting a trade war against China. 

Just asking.

Re: Big winners of Huawei ZTE USA Ban?
Will it make much difference? Huawei & ZTE are pretty much such out of the US market already.
