[I2nsf] What kind of policy that can be dynamicaly sent to "Screen" feature (was RE: "draft-dunbar-i2nsf-problem-statement-02.txt" - few comments.

Alexey,

You stated:
-“Screens”  – Juniper calls it screens, cisco doesn’t have name for it. Basically it’s protection against well-know network attacks.
Is there any run time policy (based on some events) that can be sent to the “Screen” feature?

Thanks, Linda

Hi Folks

Just read "draft-dunbar-i2nsf-problem-statement-02.txt" and would like to share my thoughts and concerns. From my point of view it’s better to not focus on the specific names but on the functionality of network security function itself.  Most probably the main use case for NSF is virtual firewall with IPS/IDS and VPN capabilities. Openstack is the ideal candidate for NSF.

We have already virtual firewall and it's good to look at it's features and functionality. I summarized most of the firewall features below:

-Access-list.  Defines which traffic are allowed to enter and pass firewall.
It's covered in https://tools.ietf.org/html/draft-ietf-netmod-acl-model-02
- Policy.  Defines which traffic are allowed to pass firewall and in which direction.
- Dos protection:  multicast, broadcast rate limiting. DHCP, ARP protection and rate-limiting. Limitation of mac-address numbers.
-“Screens”  – Juniper calls it screens, cisco doesn’t have name for it. Basically it’s protection against well-know network attacks.
- “Intrusion prevention” – Signatures of any malicious activity.
- VPN PKI- configuration of IPSEC with PKI.
- Control-plane protection of firewall itself.
- L7 filtering and proxy.
- Application detection.  Some applications uses tcp port 80 and most of the firewall can detect it.
 - Monitoring and reporting traffic. Something similar to Openflow, Jflow and etc.

What exactly is going to be covered in by i2nsf? Is i2nsf going to meet in the Dallas at IETF 92?

Thanks everybody for attention to this email.
