I think it is also important to point out here that sharing of cybersecurity playbooks is not a high volume activity. It is not akin to sharing real-time cybersecurity data related to situational awareness, or even data like threat intelligence. Efficiencies gained at the wire protocol or on-disk regarding CBOR vs JSON will not be consequential to anyone in practice for this kind of data. What is more paramount is ease of interoperability between all of the many kinds of solutions looking to produce, revise, curate, and consume these playbooks.

+1 If we want this to take off I support to be as close to the current market as possible

The initial version needs to be done in JSON, if we want the market as a whole to adopt this. I have walked the floor at RSA and Blackhat for the past 2 years talking to all of the vendors that would potentially implement this.  They all say the same thing.  If it was JSON, they could easily do it.  If it is something else, well, maybe, maybe not.  We would then be reliant on market pressure and consumers to influence vendors to adopt.  That can take 10 years or more. Usually by then, the standard is failed and the market has moved on.  Let us not be yet another standard on the dusty shelves of of the SDO Library.

 

Further, anything not JSON would require the Web2.0 world of products and APIs to support something totally different.  CBOR may take off at some point.  YANG my take off at some point.  XML may come back from the dead. But right now, today, JSON is the model that the developers of products use and know. Adding additional hurtles for the solution to be adopted is not a good idea for this first version.  

 

Overtime, once we get our first versions done and out the door and they get adopted, we can make changes or add functionality based on market demand.  If the market comes back and says, hey, we really need this done in a binary format like Protobuf, then great.  We can write a binding for that.

I fundamentally do not support the idea of not using JSON for this work.

[Med] Are you referring to application encoding or data modelling part?

 

 Over time we may write a binding document for some other serialization.  But we need something that can be implemented and have guaranteed interoperability.  

[Med] Why CBOR wouldn’t be an option here? BTW, there might be other requirements such as compactness (that may be worth when actions are enriched/augmented on-path). As a group, we don’t have yet the full set of requirements to make a design choice.

 

In order to gain mass adoption, we need a solution that can be used by the existing eco system.
