This plugin enables Foreman to receive automated vulnerability assessment and security compliance audits from Foreman hosts. You can upload SCAP compliance contents, create compliance policies out of them and assign the policies to hosts or hostgroups. foreman_openscap plugin provides three default SCAP contents, so you could start testing security compliance on RHEL6/7 and Fedora.
OpenSCAP reports (aka ARF reports) will help you find vulnerabilities on your hosts and also suggest remediation plan to fix those vulnerabilities.
Foreman OpenSCAP plugin is made of 4 components:
There are four basic concepts (entities) in OpenSCAP plug-in: SCAP Contents, Compliance Policies, ARF Reports and Tailoring Files.
SCAP Content represents SCAP DataStream XML file as defined by SCAP 1.2 standard. DataStream file contains implementation of compliance, configuration or security baselines. Users are advised to acquire examplary baseline by installing scap-security-guide package. DataStream file usualy contains multiple XCCDF Profiles. Each for different security target. The content of DataStream file can be inspected by oscap tool from openscap-scanner package. (XCCDF = Extensible Configuration Checklist Description Format, XCCDF profile = A checklist which audit specific security target)
Tailoring File is a XML file very much like SCAP Content. It represents a customization of compliance defined in a SCAP Content XML file. Additional details and instructions how to create such a file are available in the official openscap documentation.
Compliance Policy is high level concept of a baseline applied to the infrastructure. Compliance policy is defined by user on web interface. Users may assign following information to the policy:
ARF Report is XML output of single scan occurrence per single host. Asset Reporting File format is defined by SCAP 1.2 standard. Foreman plug-in stores the ARF Reports in database for later inspections.

There are a few components to install:
The easiest and recommended way is using foreman-installer. It’s as easy as running this command
> foreman-installer --enable-foreman-plugin-openscap
If you prefer the manual way, you can install it from package like this:
> yum install tfm-rubygem-foreman_openscap > foreman-rake db:migrate > foreman-rake db:seed > service httpd reload
If your distribution does not provide openscap package recent enough, you can get it from https://copr.fedorainfracloud.org/coprs/isimluk/OpenSCAP/
Please refer to the Foreman plugin manual for more information about installing Foreman plugins.
The easiest and recommended way is using foreman-installer. It’s as easy as running this command
> foreman-installer --enable-foreman-proxy-plugin-openscap
If you run Smart-Proxy with Foreman on the same host you can combine it with –enable-foreman-plugin-openscap option.
If you prefer the manual way, install this package on the Smart-Proxy server:
> yum install rubygem-smart_proxy_openscap
/etc/foreman-proxy/settings.d/openscap.yml with the appropriate settings
--- :enabled: true # Log file for the forwarding script. :openscap_send_log_file: /var/log/foreman-proxy/openscap-send.log # Directory where OpenSCAP audits are stored # before they are forwarded to Foreman :spooldir: /var/spool/foreman-proxy/openscap # Directory where OpenSCAP content XML are stored # So we will not request the XML from Foreman each time :contentdir: /var/lib/openscap/content # Directory where OpenSCAP report XML are stored # So Foreman can request arf xml reports :reportsdir: /usr/share/foreman-proxy/openscap/reports # Directory where OpenSCAP report XML are stored # In case sending to Foreman succeeded, yet failed to save to reportsdir :failed_dir: /usr/share/foreman-proxy/openscap/failed
puppet module install theforeman-foreman_scap_client
This puppet module will automatically install foreman_scap_client (if not installed) and configure the client’s
/etc/foreman_scap_client/config.yaml with all parameters needed for the operation of foreman_scap_client. The module is used by Foreman to automate the configuration and triggering of foreman_openscap_client, so you should install it in all puppet environments that your hosts use.
Once installed, Foreman will assign this class to hosts or host groups and populate the necessary parameters based on the settings you apply in Foreman under COMPLIANCE.
Starting with puppet-foreman_scap_client 0.3.14 shipped with Foreman 1.14 the Foreman plugins yum repo can be set up if you define at least Foreman’s major release version. This repository is needed to install foreman_scap_client, witch will fail otherwise. You can leave all other values to their default unless otherwise needed (Eg, your own yum repository mirror).
foreman_repo_rel- To manage the foreman-plugins yum repo and set to release version. Eg ‘1.15’, it should match your Foreman version.
foreman_repo_key- RPM Key source file for foreman-plugins repo. Note: Currently, packages are not signed. Unless set to an alternative file source, URL will be used.
foreman_repo_src- Alternative baseurl for the forman plugins repository
foreman_repo_gpg_chk- Enable / disable GPG checks. Directly passed to Yumrepo resource
As with any Foreman plugin, the recommended upgrade path is done via
yum upgrade. This will ensure that all of the packages are with the right version, dependencies
and data migrations.
Note: ARF reports are not automatically migrated and need a manual step
ARF reports in 0.5.x and Foreman > 1.11 are now part of Foreman’s reports (Reports STI), and the physical ARF report XML is now saved at the Smart-Proxy.
This requires a special migration, which needs both Foreman and Smart-Proxy up and running, with latest respective OpenSCAP plugins installed.
Since we cannot assure this during upgrade, migration of ARF reports has moved to a rake task which should be performed after upgrading.
To upgrade ARF reports from 0.4.x to 0.5.x:
foreman-rake db:migrateto ensure all other data has been migrated
<proxy_id>is the id of the Smart-Proxy with OpenSCAP feature).
Notes: to find out your Smart-Proxy id you can either run
hammer proxy list or pick the Smart-Proxy’s id from the url in web UI. please note it should be inside the square brackets
Process: During the ARF reports migration, the old ARF reports are fetched from the Foreman database, sent to the Smart-Proxy for re-processing and saving and are sent back to the Foreman in their new format - while keeping their original data.
Once the old ARF report has successfully migrated, it is deleted from the old table.
This chapter covers features that you can use in terms of Foreman and OpenSCAP integration. Everything described below assumes you’ve sucessfully installed foreman_openscap, smart_proxy_openscap and puppet-foreman_scap_client is available on your Puppet master and Foreman.
Please note: smart_proxy_openscap is required for the normal operation of foreman_openscap
You would usually start with uploading SCAP contents, then create policies of those SCAP contents and assign the policy to hosts or hostgroups.
The puppet module will install
foreman_scap_client and configure it with the needed policy information. The puppet module also adds a cron line,
which runs the SCAP client at the schedule select when creating the policy.
When installing foreman_openscap from RPM, we also add default SCAP content provided by scap-security-guide.
In previous versions, the default SCAP content was added via seed task.
In version >= 0.5.x, we are processing all of OpenSCAP content and reports in the Proxy.
And we are unsure if during installation the smart_proxy_openscap plugin is installed and enabled, so we can not seed the default SCAP content
Instead of auto-generating default SCAP content when installing foreman_openscap, you can now accomplish that with a rake task.
Creating default SCAP content
This will search for scap-security-guide SCAP contents and create SCAP content on the Foreman.
Besides the default SCAP content, you can also upload your own SCAP content.
Access SCAP contents - Hosts -> Compliance -> SCAP Contents
Create SCAP Content - You can upload any valid OpenSCAP DataStream file
(After upload, SCAP content is validated at the Smart-Proxy and SCAP profiles are extracted)
You can assign a policy in two ways:
You can access the generated reports via Hosts -> Compliance -> Reports
Report page gives information about individual rules that were checked during scan. Here you can download the actual report generated by OpenSCAP in HTML or as XML in bzip archive.
Clicking on “View full report” at the top of the page will lead you to the actual security audit report generated by OpenSCAP, with detailed information on the host’s security check and suggested remediation.
Using a Tailoring File effectively allows you to modify a policy. You can assign a Tailoring File to a Policy when creating / updating a policy. Because Tailoring File may contain multiple profiles, you have to select your modified profile as well.
You can create a new Tailoring file with SCAP Workbench
Access Tailoring files - Hosts -> Compliance -> Tailoring files
Create Tailoring - Upload your Tailoring file xml
Go to Hosts -> Compliance -> Policies
Select a Policy to edit
Go to ‘SCAP Content’ tab
Select a Tailoring file from a dropdown and then a profile that comes with it
In version 0.6.5 and higher, you can initiate scans from UI. Simply go to hosts page and select “Run OpenSCAP scan” from the dropdown menu. This will initiate a scan for all policies that are assigned to the host. foreman_remote_execution plugin of version 1.3.0 or higher needs to be installed for this feature to be enabled.
https://\<proxy_url\>/compliance/policies/\<policy_id\>/content/\<digest\>will fetch the xml from
