Yup.  This is exactly what we do, with Neutron policy.json.  I can confirm that 
this works and achieves what you need.

Perhaps you can achieve this by editing policy.json (located by default in 
/etc/neutron).

For instance you can allow only admin users to add security group rules to any 
security group by specifying the following:

"create_security_group_rule": "admin_only"

Similar rules for update and deletion of security group rules will prevent you 
from modifying existing rules.
This same set of rules will anyway allow admin users to add rules to the 
default security group.

Dear all,

in our openstack cluster, we would restrict the actions that users can do with 
security group and security group rules.

Here's what we'd like to achieve: 1. Lock down security group (and rules) so 
that only admin (or tenant admin?) can modify them. 2. Add additional rules to 
the default security group.

Can you please give me some advices on how to achieve these goals?

Thanks in advance, Giusy
