Getting started with SELinux System Administration یک امکان و ویژگی لینوکس است که مکانیزمی برای پشتیبانی از خط مشی های امنیتی سطح دسترسی هسته لینوکس ( Kernel ) را فراهم می آورد.این برنامه تحت حمایت و توسعه سازمان امنیت ملی آمریکا ( National Security Agency ) هستش و در بسیاری از توزیع های لینوکس بطور پیش فرض وجود دارد. به زبان ساده SELinux میتواند خط مشی های امنیتی برای برای اینکه کدام دسته ها ( کابران ، برنامه ها ) بتواند به کدام اجزا ( فایل ها و device ها ) دسترسی داشته باشد ، تعریف و اجرا کند. در واقع میتوان SELinux را به عنوان یک دیوار آتش ( Firewall ) داخلی برای سیستم عامل تصور کرد.

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 course will show you how to enhance your system’s secure state across Linux distributions, helping you keep application vulnerabilities at bay.
This video course 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 will probably come across as an administrator.
Style and Approach
This course offers a complete overview of SELinux administration and how it integrates with other components on a Linux system. It covers the majority of SELinux features with a mix of real-life scenarios, descriptions, and examples. This course contains everything an administrator needs to customize SELinux.

Sven Vermeulen is a long-term contributor to various free software projects and the author of various online guides and resources. He got his first taste of free software in 1997 and never looked back. In 2003, he joined the ranks of the Gentoo Linux project as a documentation developer and has since worked in several roles, including Gentoo Foundation trustee, council member, project lead for various documentation initiatives, and (his current role) project lead for Gentoo Hardened SELinux integration and the system integrity project.
During this time, Sven gained expertise in several technologies, ranging from OS-level knowledge to application servers. He used his interest in security to guide his projects further in the areas of security guides using SCAP languages, mandatory access controls through SELinux, authentication with PAM, (application) firewalling, and more.Within SELinux, Sven contributed several policies to the Reference Policy project, and he is an active participant in policy development and user space development projects.In his daily job, Sven is an IT architect in a European financial institution as well as a self-employed solution engineer and consultant.
The secure implementation of infrastructures (and the surrounding architectural integration) is, of course, an important part of this. Prior to this, he graduated with an MSc in computer engineering from Ghent University and MSc in ICT enterprise architecture from http://inno.com/, and he worked as a web application infrastructure engineer. Sven is the main author of the Gentoo Handbook, which covers the installation and configuration of Gentoo Linux on several architectures. He also authored the Linux Sea online publication (a basic introduction to Linux for novice system administrators) and SELinux System Administration and SELinux Cookbook for Packt Publishing.
