Controller-Based Networking: - focused on network - user input is a policy - uses block list security model Traditional Networking: - focused on devices - user input is a configuration - uses allow list security model In Controller-Based Networking everything is blocked by default. https://www.computernetworkingnotes.com/ccna-study-guide/traditional-vs-controller-based-networking.html

I am sorry to say that Block list and allow list need to the swapped in your answer.

given answers are correct Controller-based networking employs an allow list (whitelist) security model, where only authorized traffic is permitted based on defined policies, so everything is blocked unless you allow it.

Anyone have any idea on what they are referring to regarding the allow list and block list?

Zero based trust is the new "way" and instead of starting where everything is allowed unless denied, zero trust starts with everything blocked and everything you want to allow has to be enabled.

Isn't denying everything by default as traditional configuration ACLs have worked? I don't see any difference, so I'll call marketing bs.

Actually no, if you don't apply and ACL everything is open an available to pass (on cisco devices) and from default you don't have any ACLs created on the device, so default deployment is wide open to pass any traffic.

I believe that in traditional networks we focus more on blocks when creating ACLs. Unlike Software Defined Networks such as ACI (Application Policy Infrastructure Controller (APIC)) which focuses more on Permission Policies or SDA networks (DNA-Center controller) which also focuses on Permissions but with SGT, as these networks are Intent Based Networks (IBN) leaving the blocks and the rest to the Artificial Intelligence to do.
