Satellite 6.3 Feature Overview: Tailoring Files

Updated 2018-02-21T15:48:58+00:00

Satellite 6.3 introduces the Tailoring Files feature. Tailoring Files allow existing OpenSCAP policies to be tailored, or customised, without forking or rewriting the policy.

This feature overview will set a little background on SCAP, then go into more detail about Tailoring Files and how to upload and assign them to a policy.
This content takes heavily from section 6 of the Satellite 6.3 Administering Red Hat Satellite guide, specifically section 6.1: What is SCAP and section 6.4: Tailoring Files.

About SCAP

The Security Content Automation Protocol or SCAP enables the definition of security configuration policies. For example, a security policy might specify that for hosts running Red Hat Enterprise Linux, login via SSH is not permitted for the root account. In Satellite 6, tools provided by the OpenSCAP project are used to implement security compliance auditing. For more information about OpenSCAP see the Red Hat Enterprise Linux 7 Security Guide.

SCAP content is a datastream format containing the configuration and security baseline against which hosts are checked.
You can either create SCAP content or obtain it from a vendor. Supported profiles are provided for Red Hat Enterprise Linux in the scap-security-guide package.

SCAP Content in Satellite uses the XCCDF Profile. An XCCDF profile is a checklist against which a host or host group is evaluated. Profiles are generally created to verify compliance with a standard, whether that be an industry standard or a custom standard.

Information on how to download, deploy, modify, and create your own SCAP content is covered in the Red Hat Enterprise Linux 7 Security Guide or Red Hat Enterprise Linux 6 Security Guide.

Tailoring Files

As mentioned above, Tailoring Files allow existing OpenSCAP policies to be customised without forking or rewriting the policy.

It is important to note that the Tailoring files feature does not provide the abililty to create tailoring files. A Tailoring file can be created using SCAP Workbench, available at https://www.open-scap.org.
For more information on using the SCAP Workbench tool, see Customizing SCAP Security Guide for your use-case.

Once you have a Tailoring file you can upload it and assign the Tailoring File to a policy.
