There are few things as critical to a system administrator's work as security. According to Bill McCarty, author of "SELinux: NSA's Open Source Security Enhanced Linux," as the number and variety of software vulnerabilities and attacks continue to accelerate, security is probably the most important topic in computing today. But the ongoing search for a more secure operating system has often left everyday production computers far behind their experimental research cousins. SELinux (Security Enhanced Linux) dramatically changes this situation.
"I now believe that SELinux is the most important computing technology for Linux users that I've seen in the last several years," states McCarty. "Obviously, others agree that SELinux is important and useful: SELinux has been incorporated into Fedora Core, Gentoo, and SUSE Linux." In addition, the new Red Hat Enterprise Linux 4, expected to release in first quarter 2005, will be a fully supported Linux distribution featuring SELinux. A system administrator for SELinux needs a wide range of knowledge, such as the principles behind the system, how to assign different privileges to different groups of users, how to change policies to accommodate new software, and how to log and track what is going on. And this is where the book "SELinux" is invaluable. "Readers learn how to install, initially configure, and maintain Linux systems using SELinux," says McCarty. This book is written for the typical system administrator who's trying to figure out how to keep bad guys out of the systems for which he or she is responsible. Topics include: -A readable and concrete explanation of SELinux concepts and the SELinux security model -Installation instructions for numerous distributions -Guidelines for basic system and user administration -A detailed dissection of the SELinux policy language -Examples and guidelines for altering and adding policies With "SELinux," a high-security computer is within reach of any system administrator. If you want an effective means of securing your Linux system--and who doesn't?--this book provides the means.
