1. Security Groups Aswin Suryanarayanan and Ravindra Kencheppa

2. Openstack Security Groups Fixed Security Rules Added despite of security group is selected or not It adds a predefined set of rules which is not customizable Security Group CRUD The rules needs to be applied to the port when SG is selected. It adds user customizable rules

3. Openstack Fixed Security Groups  Applied when a vm port is created. Ingress  Allows DHCP traffic and same net-traffic.  Drop all the other traffic Egress  Drop any Source IP/Mac pair other than of the connected vm  Drop any DHCP server traffic from the VM Conntrack Rules(Both Egress and Ingress)  Drop packets that appear related to an existing connection (e.g. TCP ACK/FIN) but do not have an entry in conntrack  Allow packets associated with a known session

4. Opendaylight Security Groups – Current Fixed Security Groups The DHCP rules are added. The rest of the rules needs to be added. Conntrack rules can be added only if OVS add support for the same Security Group CRUD Not supported

5. Modules to work on Neutron has AD-SAL code, needs to be ported to MD-SAL NetVirt Add listener for the MD-SAL notification Add logic to process the CRUD operations in PortSecuirtyHandler Uncomment the code in OF13Provider to enable SecurityGroup handling in an interface update. In Egress/IngressAclService add logic to support multiple protocols.
