Set SELinux Mode

Introduction

In this challenge, you will learn how to set the enforcing and permissive modes for SELinux on a Red Hat Enterprise Linux (RHEL) system. SELinux is a security feature in RHEL that provides mandatory access control (MAC) to protect the system from unauthorized access and potential security threats. Understanding how to manage SELinux modes is a crucial skill for RHEL system administrators.

Set SELinux to Enforcing Mode

Tasks

• Set the SELinux mode to enforcing.
• Verify that SELinux is in enforcing mode.

Requirements

• The default user account for this challenge is labex with the password labex.
• All operations should be performed in the /home/labex directory or its subdirectories.
• Use the semanage command to set the SELinux mode.

Example

After setting SELinux to enforcing mode, the output of the getenforce command should be:

Enforcing

Set SELinux to Permissive Mode

Tasks

• Set the SELinux mode to permissive.
• Verify that SELinux is in permissive mode.

Requirements

• The default user account for this challenge is labex with the password labex.
• All operations should be performed in the /home/labex directory or its subdirectories.
• Use the semanage command to set the SELinux mode.

Example

After setting SELinux to permissive mode, the output of the getenforce command should be:

Permissive

Summary

In this challenge, you learned how to set the enforcing and permissive modes for SELinux on a Red Hat Enterprise Linux (RHEL) system. You practiced using the semanage command to manage the SELinux mode and verified the changes using the getenforce command. Understanding how to manage SELinux modes is an essential skill for RHEL system administrators, as it helps to ensure the security and integrity of the system.
