Dear Yue,

I see your point.

Please refer to the "Information Model of NSFs Capabilities" document 
(draft-ietf-i2nsf-capability-02).
To the best of my knowledge, data models will be (derived from and) made 
coherent with the Information Model as soon as it will be (close to) final.


Regards,
Aldo

But in your comment, such kind of functions (e.g. ips, ids, etc.) are repackaged group of security capabilities. So I confused with it.

>> 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.
