Overview
The "Red Hat Security: Linux in Physical, Virtual, and Cloud" (RH415) course is designed for security and system administration personnel who manage the secure operation of computer systems running Red Hat Enterprise Linux on physical hardware, as virtual machines, or as cloud instances both in private data centers and on public cloud platforms.
Maintaining the security of computing systems is a process of managing risk through the implementation of processes and standards backed by technologies and tools. "Red Hat Security: Linux in Physical, Virtual, and Cloud" (RH415) is designed for security administrators and system administrators who need to manage the secure operation of servers running Red Hat Enterprise Linux, whether deployed on physical hardware, as virtual machines, or as cloud instances. You will learn about technologies and tools that can be used to help you implement and comply with your security requirements, including the kernel's Audit subsystem, AIDE, SELinux, OpenSCAP and SCAP Workbench, USBGuard, PAM authentication, and Network-Based Device Encryption. You will learn to monitor compliance and to proactively identify, prioritize, and resolve issues by using OpenSCAP, Red Hat Insights, Red Hat Satellite, and Red Hat Ansible Automation Platform. You will have a basic introduction to how Red Hat Ansible Automation Platform automates the deployment of remediation to systems, by using Ansible Playbooks from OpenSCAP or Red Hat Insights.
This course is based on RHEL 9.2, Ansible Core 2.14, Red Hat Ansible Automation Platform 2.4, Satellite 6.14, and OpenSCAP 1.3.7.
Maintaining the security of computing systems is a process of managing risk through the implementation of processes and standards backed by technologies and tools. In this course, you will learn about resources that can be used to help you implement and comply with your security requirements.
Following course completion, you will receive a 45-day extended access to hands-on labs for any course that includes a virtual environment.
Who should attend

Course Objectives
Impact on the organization
This course is intended to develop the skills that are needed to reduce security risk and to implement, manage, and remediate compliance and security issues in an efficient way at scale. The tools and techniques can help to ensure that systems are configured and deployed in a way that meets security and compliance needs, that they continue to meet those requirements, and that as those requirements are revised, all existing systems can be audited, and remediations and changes consistently applied. This outcome may help the business to efficiently reduce the risk of security breaches, which have a high cost in business disruption, brand erosion, loss of customer and shareholder trust, and financial costs for post-incident remediation. In addition, the organization may be able to use the tools in this course to help demonstrate that the compliance requirements set by customers, auditors, or other stakeholders have been met.
Impact on the individual
- As a result of attending this course, students should be able to use security technologies included in Red Hat Enterprise Linux to manage security risk and help meet compliance requirements.
- Analyze and remediate system compliance by using OpenSCAP and SCAP Workbench, and using and customizing baseline policy content that is provided with Red Hat Enterprise Linux.
- Monitor security-relevant activity on your systems with the kernel's Audit infrastructure.
- Explain and implement advanced SELinux techniques to restrict access by users, processes, and virtual machines.
- Confirm the integrity of files and their permissions with AIDE.
- Prevent unauthorized USB devices from being used with USBGuard.
- Protect data at rest but provide secure automatic decryption at boot by using Network-Bound Device Encryption (NBDE).
- Proactively identify risks and misconfigurations of systems and remediate them with Red Hat Insights.
- Analyze and remediate compliance at scale with OpenSCAP, Red Hat Insights, Red Hat Satellite, and Red Hat Ansible Automation Platform.
