[AusNOG] SDWAN Security

[Tim Dooley]

It sounds like you need to boil it down to what does your network requires (or may soon require) and use that information to try and find shortcomings in the meraki offering.

Also do you need to minimise management overhead (not that there's a lot of overhead for a running network).

If people see issues with my information, please explain them, I'm keen to learn more on this topic from those with more experience.

Heya,

How are those solutions more suited to swapping in for an MPLS network? Aren't they all just some flavour of vpn with a cloud frontend, and some neat fail over behaviours?

I am in the unenviable positive of having to prove "why not meraki", rather than "what's the best option". Hopefully that comes later, but the meraki solution has some...investment...to overcome.

And that can only be done with hard facts

Hi Dusty,

I don’t think you will find that Cisco meraki is not a proper SDWAN solution. It’s just a glorified VPN with a cloud dashboard. If you call that SDWAN then SDWAN has been around for 30 years then.....

You need to be looking at proper SDWAN solutions like Velocloud(VMware), Cisco Viptella, Peplink, etc. These are proper SDWAN solutions that can replace an MPLS.

Hi Dusty,

Full disclosure: I work for VMware (we have a SD-WAN offering) but I’ll keep it agnostic—

Hi Folks,

After a number of years being more managerial than technical, I find myself staring at a proposal to swap a perfectly good MPLS network with some Meraki shenanigans.

This, frankly, gives me the heebie jeebies.

I've done a bunch of poking around but, alas, it is remarkably difficult to locate reliable analyses of the actual security (or lack thereof) of these solutions - plenty of glossy marketing and whizzbang, not a lot of facts.

Can anyone point me in the direction of some decent whitepapers, blogs, etc about the relative merits of these things?

Thanks!

(tl;dr: talk to your friendly vendor SE.)

What sort of collateral would you look for, to give warm fuzzies, if you were evaluating a traditional WAN routing platform?

You should be able to find security whitepapers and other technical documents that describe management and data plane security, use of crypto/PKI etc.

Vendors targeting enterprise customers should be putting their products through security evaluation frameworks such as Common Criteria — look for certification, in-flight or completed, against the Network Device collaborative Protection Profile (NDcPP) plus optional modules like VPN. Crypto libraries may be FIPS 140-2 [US centric] certified.

For vendors offering things as-a-service, certifications and statements of conformance against other regulatory frameworks should be applicable (SOC, FedRAMP [again US centric], IRAP etc. may exist).

Cheers,
Dale
