File Size: 1.06 Mb

Be it for personal use or for larger enterprises, system administrators have often an ungrateful job of protecting the system from malicious attacks and undefined application behavior. Providing security to systems is a major part of their job description, and to accomplish this there are a large set of security technologies are at the administrator's disposal, such as firewalls, file integrity validation tools, configuration enforcement technologies, and many more. Major parts of system security is the authentication of users, authorization of these users, and auditing of all changes and operations made on the system. Users, however, are becoming more experienced with working around regular access controls that are designed to keep the system safe, and application vulnerabilities are often exposing much more of the system than what the application should have access to.

In this book, we will describe the SELinux concepts and show how to leverage SELinux to improve the secure state of a Linux system. Together with examples and command references, this book will offer a complete view on SELinux and how it integrates with various other components on a Linux system.
