SELinux & AppArmor Guide
Practical Mandatory Access Control for Securing Linux Systems
What's Included:
Key Highlights
- Deep focus on SELinux with real-world examples
- Complete AppArmor coverage for comparison
- Policy writing and troubleshooting techniques
- Container and virtualization security
- Production-ready operational guidance
Overview
Master SELinux and AppArmor with practical, real-world examples. Learn mandatory access control, policy creation, troubleshooting, service hardening, containers, and production security best practices.
The Problem
Linux systems are often compromised due to overly permissive access controls. Many administrators disable SELinux or AppArmor because they lack the knowledge to configure and troubleshoot them properly.
The Solution
This book provides a clear, practical guide to mastering SELinux and AppArmor, enabling administrators to secure Linux systems without breaking functionality.
About This Book
Master Mandatory Access Control on Linux
SELinux & AppArmor Guide is a practical, in-depth resource for implementing mandatory access control (MAC) on Linux systems using SELinux and AppArmor.
Traditional Linux permissions are no longer sufficient to protect modern systems against advanced threats. Mandatory Access Control adds an additional security layer that limits damage even when services are compromised.
Why SELinux Matters
SELinux is the most powerful and widely deployed MAC framework in the Linux ecosystem. It is trusted by enterprises, governments, and security-critical infrastructures worldwide.
This book focuses primarily on SELinux, while also providing comprehensive coverage of AppArmor to help you choose the right approach for your environment.
What You Will Learn
- SELinux architecture, modes, and enforcement models
- Understanding and managing SELinux contexts
- Diagnosing and resolving AVC denials
- Writing and customizing SELinux policies
- AppArmor profile management and troubleshooting
- Securing services with mandatory access control
- MAC in containers and virtualized environments
- Automating SELinux and AppArmor management
- Operational best practices and incident response
Designed for Production Environments
All examples are based on real production scenarios. You will learn not only how to configure SELinux, but how to operate it safely, troubleshoot issues efficiently, and integrate it into modern DevOps workflows.
The appendices provide command references, troubleshooting guides, and decision matrices that make this book a long-term professional reference.
