The compliance policies page is part of the OpenSCAP plugin and will only exist if this plugin is installed on your orcharhino.
The compliance policies page can be accessed via the hosts menu:
Hosts > Compliance > Policies
A compliance policy is a high level concept of orcharhino’s OpenSCAP plugin. It requires the setting of a specific XCCDF profile from some chosen SCAP content, optionally using a tailoring file, for use with individual hosts. They are also associated with a schedule for running audits and can be associated with any number of host groups.
Refer to the OpenSCAP compliance policies page for more information.
