I completely agree with Diego.The purpose of a capability model is to 'understand each other' with precise, thus more granular, information that allows avoiding any ambiguity. Hence, a controller could automatically decide how to use NSFs.
It is pretty known that marketing units repackage NSFs with brand new names that are good for selling software and equipment, but increase confusion for technical people (and for automatic systems as well).
Imagine a scenario where a company make an epsilon modification to an IDS and sells it as a Smart IDS (SIDS). An automatic system must understand what 'Smart' means and what a SIDS can do that an IDS cannot actually do already. And now think about a concrete case, the IPS...
So, in my opinion, flat enumeration of capabilities is the only way to deal with issue (different fields, like the actions that enforce, the flows/traffic they can identify, the events they react to, etc., i.e., the capability model we are authoring).

If you associate a capability action (let's say collect-attack-evidence-enable) with a particular kind of device (as part of the antivirus branch) I would not be able to declare or use that particular capability unless the provider has stated the function is an antivirus, and therefore consider all the other capabilities for the antivirus. What is more, this prevents to have a common semantics for something like collect-attack-evidence-enable if you have to declare it under other branches. My understanding is that we have to deal with flat enumeration of capabilities, but I might be completely mistaken from the beginning...

As an example, rather than thinking of "antivirus", I'd propose to think about "content analysis" or "content scanning" capabilities.

However, I think it only list the corresponding names. And each type of the secuity function action (i.e. ips, antivirus, etc.) should have many selective profiles that could be executed. Therefore, we proposed a draft, draf-dong-i2nsf-asf-config-00, that specifies the configuration detail for each of the security function profile settings. And the NSF-facing data model is able to reference these profiles. This -00 version of draft only contains the antivirus, ips, and anti-ddos profiles. * Antivirus: The following figure shows the top-level tree diagram for antivirus profile settings.

Name:draft-dong-i2nsf-asf-config Revision:00 Title:Configuration of Advanced Security Functions with I2NSF Security Controller Document date:2018-06-30 Group:Individual Submission Pages:29 URL: https://www.ietf.org/internet-drafts/draft-dong-i2nsf-asf-config-00.txt Status: https://datatracker.ietf.org/doc/draft-dong-i2nsf-asf-config/ Htmlized: https://tools.ietf.org/html/draft-dong-i2nsf-asf-config-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-dong-i2nsf-asf-config Abstract: This draft defines a network security function (NSF-) facing interface of the security controller for the purpose of configuring some advanced security functions. These advanced security functions include antivirus, anti-ddos, and intrusion prevention system (IPS). The interface is presented in a YANG data model fashion and can be used to deploy a large amount of NSF blocks that all support above mentioned functions in the software defined network (SDN) based paradigm. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
