Security

OpenStack services support various security methods including password, policy, and encryption. Additionally, supporting services including the database server and message broker support password security.

To ease the installation process, this guide only covers password security where applicable. You can create secure passwords manually, but the database connection string in services configuration file cannot accept special characters like “@”. We recommend you generate them using a tool such as pwgen, or by running the following command:

$ openssl rand -hex 10

For OpenStack services, this guide uses SERVICE_PASS to reference service account passwords and SERVICE_DBPASS to reference database passwords.

The following table provides a list of services that require passwords and their associated references in the guide.

OpenStack and supporting services require administrative privileges during installation and operation. In some cases, services perform modifications to the host that can interfere with deployment automation tools such as Ansible, Chef, and Puppet. For example, some OpenStack services add a root wrapper to sudo that can interfere with security policies. See the Compute service documentation for Pike, the Compute service documentation for Queens, or the Compute service documentation for Rocky for more information.

The Networking service assumes default values for kernel network parameters and modifies firewall rules. To avoid most issues during your initial installation, we recommend using a stock deployment of a supported distribution on your hosts. However, if you choose to automate deployment of your hosts, review the configuration and policies applied to them before proceeding further.
