Paul, I am so sorry that the BGP session running longer than expected. I will come to you in 5 minutes.

However, for points 1 and 2, we need to bridge I2NSF and SFC (or SDN). At least, we can work for the interface with SFC within IETF. Thanks. Paul On Thu, Nov 21, 2019 at 11:50 AM Diego R. Lopez <[email protected]<mailto:[email protected]>> wrote: Hi Paul, Just to frame today’s discussion, let me remark I find especially interesting points (3) and (4), that I believe can only happen within I2NSF. We can connect (3) with the ECA discussions happening in OPSAWG and NMRG, and I see (4) as an interesting opportunity for consolidating and achieving the full potential of the capability model.

I2NSF NSF Monitoring YANG Data Model - Security Policy Translator Draft Update (Chaehong Chung, 5 min) - Open Discussion: Possible Work Items for I2NSF Rechartering (30 min) I will report the progress of data model drafts. I would like to discuss the rechartering of I2NSF WG with you. I suggest four work items as the 2nd phase I2NSF. 1. YANG data model of the interface between I2NSF Security Controller and SDN Switch Controller 2. YANG data model of the interface between I2NSF Security Controller and SFC Classifier 3. Configuration of Advanced Security Functions with I2NSF Security Controller 4. Policy Object for Interface to Network Security Functions (I2NSF) Let me explain why each of them is important for I2NSF. 1. YANG data model of the interface between I2NSF Security Controller and SDN Switch Controller According to the I2NSF Applicability Draft and I2NSF Hackathon Project, the SDN switches can perform simple packet filtering and the firewall NSF can perform complicated packet filtering. For this two separated packet filtering, the security policy about a traffic flow should be delivered to an SDN Switch Controller. For the delivery of a security policy to the SDN network, the interface between the I2NSF Security Controller and the SDN Switch Controller is needed. 2. YANG data model of the interface between I2NSF Security Controller and SFC Classifier According to the I2NSF Applicability Draft and I2NSF Hackathon Project, a security policy (e.g., time-based web filtering) requires a Service Function Chaining (SFC) such as firewall and web filter. For this SFC path specification of a security policy, a security about a traffic flow should be delivered to an SFC Classifier. For the delivery of a security policy to specify the service function path in the SFC Classifier, the interface between the I2NSF Security Controller and the SFC Classifier is needed. 3. Configuration of Advanced Security Functions with I2NSF Security Controller (https://tools.ietf.org/html/draft-dong-i2nsf-asf-config-01<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fhtml%2Fdraft-dong-i2nsf-asf-config-01&data=02%7C01%7Clinda.dunbar%40futurewei.com%7Cf32f76b00e044df072f108d76e37cd88%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637099058286898310&sdata=kKg1vrUCsGmWcS3T%2F83oLrg9jTJ0q8tQb7uiMhDYDRg%3D&reserved=0>) With the current NSF-Facing Interface, we can configure basic security functions, such as firewall, deep packet inspection, and DDoS attack mitigator. For rich network security functions, the YANG data model of advanced security services needs to be developed. 4. Policy Object for Interface to Network Security Functions (I2NSF) (https://tools.ietf.org/html/draft-xia-i2nsf-security-policy-object-01<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fhtml%2Fdraft-xia-i2nsf-security-policy-object-01&data=02%7C01%7Clinda.dunbar%40futurewei.com%7Cf32f76b00e044df072f108d76e37cd88%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637099058286908306&sdata=wnEg%2BjZTZYdB83PPl0TSzT%2BuOH0qlguDFv1sTSVkGNU%3D&reserved=0>) Policy objects for I2NSF security policy rules can provide the I2NSF system with reusability for security policy construction by defining essential attributes for each policy object. This will be useful for security policy rule generation in the I2NSF system. Welcome your feedback. Thanks.
