Book Description
Do you have the crucial job of protecting your private and company
systems from malicious attacks and undefined application behavior? Are
you looking to secure your Linux systems with improved access controls?
Look no further, intrepid administrator! This book will show you how to
enhance your system's secure state across Linux distributions, helping
you keep application vulnerabilities at bay.
This book covers the core SELinux concepts and shows you how to leverage
SELinux to improve the protection measures of a Linux system. You will
learn the SELinux fundamentals and all of SELinux's configuration
handles including conditional policies, constraints, policy types, and
audit capabilities. These topics are paired with genuine examples of
situations and issues you may come across as an administrator. In
addition, you will learn how to further harden the virtualization
offering of both libvirt (sVirt) and Docker through SELinux.
By the end of the book you will know how SELinux works and how you can
tune it to meet your needs.
What you will learn
- Analyze SELinux events and selectively enable or disable SELinux
enforcement
- Manage Linux users and associate them with the right role and
permission set
- Secure network communications through SELinux access controls
- Tune the full service flexibility by dynamically assigning resource
labels
- Handle SELinux access patterns enforced through the system
