Implementing Authorization, Authentication and Accounting Methods on a Linux Server (XK0-006)

This lab aligns to the following CompTIA Linux+ (XK0-006) exam objectives:

  • 3.1: Given a scenario, implement authorization, authentication, and accounting controls on a Linux system.
  • 5.4: Given a scenario, analyze and troubleshoot security issues on a Linux system.

By the end of this lab, you will be able to:

  • Configure Polkit rules to delegate service management privileges to specific user groups.
  • Implement password quality and account lockout policies using PAM.
  • Configure an LDAP directory and add user accounts to a directory service.
  • Describe the function of Kerberos and Samba in Linux authentication environments.
  • Use system logging and audit tools to monitor access and account activity on a Linux server.

Overview

Welcome to the Implementing Authorization, Authentication and Accounting Methods on a Linux Server lab. In this lab, you will configure the core authentication and access control components used in Linux environments, while also examining how system activity is recorded and analyzed through logging.

You will delegate service restart privileges using Polkit, enforce password complexity and account lockout policies with PAM, and deploy an LDAP directory on Ubuntu. You will also explore Kerberos and Samba configurations, and use tools such as journalctl and auditd to monitor authentication events, service behavior, and policy enforcement activity.

By the end of this lab, you will have practical experience configuring major Linux AAA controls and using system logs to investigate access issues, validate system behaviour, and support security monitoring in real-world environments.

You will complete the following two activities in this lab:

  • Reading Assignment – Log Files and Security Investigation
  • Exercise 1 – Implementing AAA Controls on a Linux System
