SELinux by Example or Excel 2002 for Dummies

SELinux by Example: Using Security Enhanced Linux (Prentice Hall Open Source Software Development Series)

Author: Frank Mayer

SELinux offers Linux/UNIX integrators, administrators, and developers a state-of-the-art platform for building and maintaining highly secure solutions. Now that SELinux is included in the Linux 2.6 kernel—and delivered by default in Fedora Core, Red Hat Enterprise Linux, and other major distributions—it's easier than ever to take advantage of its benefits.

SELinux by Example is the first complete, hands-on guide to using SELinux in production environments. Authored by three leading SELinux researchers and developers, it illuminates every facet of working with SELinux, from it's architecture and security object model to its policy language. The book thoroughly explains SELinux sample policies—including the powerful new Reference Policy—showing how to quickly adapt them to your unique environment. It also contains a comprehensive SELinux policy language reference and covers exciting new features in Fedora Core 5 and the upcoming Red Hat Enterprise Linux version 5.

  • Thoroughly understand SELinux's access control and security mechanisms
  • Use SELinux to construct secure systems from the ground up
  • Gain fine-grained control over kernel resources
  • Write policy statements for type enforcement, roles, users, and constraints
  • Use optional multilevel security to enforce information classification and manage users with diverse clearances
  • Create conditional policies that can be changed on-the-fly
  • Define, manage, and maintain SELinux security policies
  • Develop and write new SELinux security policy modules
  • Leverage emerging SELinux technologies to gain even greater flexibility
  • Effectively administer any SELinux system

Just because electronic spreadsheets like Excel 2002 have become almost as commonplace on today's personal computers as word processors and games doesn't mean that they're either well understood or well used.

Well, it's high time to change all that.

Excel 2002 For Dummies will help you make some sense out of the rash of icons, buttons, and boxes that you're going to be facing day after day.
