Chapter 1. An introduction to security issues

1.1. Abstract

Rule Set Based Access Control (RSBAC) is a Unix (currently Linux) based security framework, that consists of kernel enhancements and related patches available for recent Linux kernel versions. It controls access to computer resources. The proper use of RSBAC renders many commonly used workarounds for Unix security superfluous and enhances others. RSBAC offers high granularity and flexibility and can be extended using a well defined API by means of kernel(-like) modules.
