Security hardening
|
|
==================
|
|
|
|
OpenStack-Ansible automatically applies host security hardening configurations
|
|
using the `openstack-ansible-security`_ role. The role uses a version of the
|
|
`Security Technical Implementation Guide (STIG)`_ that has been adapted for
|
|
Ubuntu 14.04 and OpenStack.
|
|
|
|
The role is applicable to physical hosts within an OpenStack-Ansible deployment
|
|
that are operating as any type of node, infrastructure or compute. By
|
|
default, the role is enabled. You can disable it by changing a variable
|
|
within ``user_variables.yml``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
apply_security_hardening: false
|
|
|
|
When the variable is set to ``true``, the ``setup-hosts.yml`` playbook applies
|
|
the role during deployments.
|
|
|
|
You can apply security configurations to an existing environment or audit
|
|
an environment using a playbook supplied with OpenStack-Ansible:
|
|
|
|
.. code-block:: bash
|
|
|
|
# Perform a quick audit using Ansible's check mode
|
|
openstack-ansible --check security-hardening.yml
|
|
|
|
# Apply security hardening configurations
|
|
openstack-ansible security-hardening.yml
|
|
|
|
For more details on the security configurations that will be applied, refer to
|
|
the `openstack-ansible-security`_ documentation. Review the `Configuration`_
|
|
section of the openstack-ansible-security documentation to find out how to
|
|
fine-tune certain security configurations.
