In this tutorial, we will show you how to install OpenSCAP on Fedora 38. OpenSCAP is an open-source security compliance solution that helps administrators assess the security posture of their systems and ensure compliance with industry standards. It provides a framework for automated vulnerability scanning, configuration management, and policy compliance. With OpenSCAP, you can identify security vulnerabilities, misconfigurations, and other issues, and take appropriate remediation actions.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of OpenSCAP on a Fedora 38.
- A server running one of the following operating systems: Fedora 38.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for OpenSCAP.

This command sets up OpenSCAP to use the standard profile and saves the scan results in the
scan-results.xml file. It also generates a report in HTML format named
Step 4. Exploring OpenSCAP Command Line Examples.
Now that you have OpenSCAP installed on your Fedora 38 system, let’s explore some command line examples to demonstrate its capabilities:
- Scanning the System for Vulnerabilities:
To scan your system for vulnerabilities using OpenSCAP, run the following command:
sudo oscap xccdf eval --profile xccdf_org.ssgproject.content_profile_standard --results scan-results.xml /usr/share/xml/scap/ssg/content/ssg-fedora38-xccdf.xml
This command performs a vulnerability scan using the standard profile and saves the results in the
- Generating Compliance Reports:

sudo oscap xccdf eval --profile my_custom_profile --results scan-results.xml --rules my_custom_rules.xml /usr/share/xml/scap/ssg/content/ssg-fedora38-xccdf.xml
This command performs a scan using a custom profile (
my_custom_profile) and custom rules (
- Scheduling Automated Scans:
To schedule recurring OpenSCAP scans for continuous system monitoring, you can utilize cron or other scheduling tools. Create a shell script that includes the desired OpenSCAP command and use cron to schedule its execution at specified intervals.
