+
+Launchpad blueprint:

+
+Proposal to add security group extension in PLUMgrid plugin.
+
+Problem description
+===================
+
+Currently, PLUMgrid plugin does not support security group extension. This
+feature is required to support PLUMgrid security policy framework and provide
+all the functionality exposed in security group API extensions today.
+
+Proposed change
+===============
+
+Introduce Neutron security group extension in PLUMgrid plugin. This will
+include support for all existing security group and rules APIs:
+1) CRUD operations for security groups
+2) CRUD operations for security group rules

+Implementation
+==============

+security groups fits well in the subset of cababilities provided by PLUMgrid.
+
+All the existing worklows supported by Neutron API[1] or python-neutron
+client[2] will be suppoted.
