SELinux System Administration – Second Edition – مدیریت سیستم سیلینوکس

Selinux کوتاه شده عبارت Security-Enhanced Linux به معنی لینوکس با امنیت بهبود یافته است. این ماژول کرنل ( Kernel ) در 22 دسامبر سال 2000 توسط آژانس ملی امنیت آمریکا و تحت لایسنس GPL توسعه داده شد و هدف آن بهبود امنیت کلی سیستم عامل لینوکس بود. سیستم نظارتی selinux از نوع MAC می باشد که کوتاه شده عبارت mandatory access control ( کنترل دسترسی اجباری ) است. در این سامانه ، سیستم عامل دسترسی های سیستمی را کنترل کرده و در مواردی که امنیت در خطر باشد ، محدودیت هایی را اعمال می کند.

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.

Sven Vermeulen

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, 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.
