Hi Paul,Thank you for your answer and for addressing my comments. I am fine with all your proposed changes, with one observation.> => [PAUL] RFC 8329 (Framework for Interface to Network Security Function) is anInformational RFC. If RFC 8329 is moved to Normative Reference, the ID-NITS tool
(https://www6.ietf.org/tools/idnits) returns an error as follows:
“** Downref: Normative reference to an Informational RFC: RFC 8329”
Thus, we put RFC 8329 as an Informative Reference.I am aware that placing RFC 8329 as Normative creates a downref. This is admitted provided that the issue is justified and registered as such ar LC time. This is a non-blocking comment, anyway, so I will let you and the WG decide.Regards,DanOn Wed, Jan 26, 2022 at 3:23 PM Mr. Jaehoon Paul Jeong <jaehoon.paul@xxxxxxxxx> wrote:Hi Dan,Here is the revised draft of NSF-Facing Interface according to your comments:Patrick and I have worked on the revision.I attach the revision letter to explain our revision for your comments.Thanks.Best Regards,PaulOn Tue, Jan 25, 2022 at 7:26 PM Dan Romascanu via Datatracker <noreply@xxxxxxxx> wrote:Reviewer: Dan Romascanu

Summary:
This document defines a YANG data model for configuring security policy rules
on Network Security Functions (NSF) in the Interface to the Network Security
Functions (I2NSF) framework. It's a solid, well-written and complete document.
It needs to be read in the context and together with several other documents
belonging to the I2NSF deliveries. The document is Ready from the perspective
of Gen-ART with a couple of minor non-blocking issues and a few editorial
problems that could be easily clarified and fixed if needed.
Major issues:
Minor issues:
1. How can RFC 8329 be only an Informative Reference. The Introduction dully
states that the YANG module is based upon the framework / architecture defined
in RFC 8329, and Section 4 uses RFC 8329 in several reference clauses.
2. Section 4.
> leaf frequency {
type enumeration
Is this enumeration sufficient (once, daily, weekly, monthly, yearly)? Are not
more cases needed? more flexibility?
Nits/editorial comments:
1. Section 3.3:
> A condition clause of generic network security functions is defined as IPv4
condition, IPv6 condition, TCP condition, UDP condition, SCTP condition, DCCP
condition, and ICMP (ICMPv4 and ICMPv6) condition.
Should not be rather 'or' instead of 'and'?
2. Section 4:
description of identity acces-violation
> "Identity for access-violation. Access-violation system
event is an event when a user tries to access (read, write,
create, or delete) any information or execute commands above
their privilege."
'above their privilege' is vague - probably meaning not-conformant with the
access profile
3. Section 4
identity memory-alarm
description
"Identity for memory alarm. Memory is the hardware to store
information temporarily or for a short period, i.e., Random
Access Memory (RAM). A memory-alarm is emitted when the RAM
usage exceeds the threshold.";
memory-alarm is emitted when the memory usage is exceeding the threshold - RAM
example does not really help, the alarm applies to all types of memory
4. Section 4
identity ot {
base device-type;
description
"Identity for Operational Technology devices";
}
identity vehicle {
base device-type;
description
"Identity for vehicle that connects to and shares
data through the Internet";
}
reference clauses would help - what is an OT and a 'vehicle' (in this context)?
5. Section 4
> identity forwarding {
base egress-action;
description
"Identity for forwarding. This action forwards the packet to
another node in the network.";
}
'This action forwards ... ' sounds odd. The action consists of forwarding, but
does not perform it. I suggest re-wording. There are a few more such instances
of 'This action [does] ...
