Create a Custom Scan Policy with OpenSCAP

In this hands-on lab, we will use the SCAP Workbench tool to create a custom policy and scan a host with it. SCAP Workbench comes with preconfigured rule sets, from which we can create our own custom policies we'll use to scan our environment for compliance with internal security policies. *This course is not approved or sponsored by Red Hat.*
