Implementation and Automatic Testing for Security Enhancement of Linux Based on Least Privilege

Now-a-days, technologies of information security have been attached more and more importance to and it's a critical problem to take measures to ensure the reliability of related trustworthy software such as Secure Operating Systems (SOSs). Thereafter, it's always necessary for such systems to be taken complete and rigorous security test and evaluation among development team and/or by third-party security certification organization. However, such software testing is usually time consuming, cost consuming and bore some and thus technologies of software testing automation have alluring application foreground in that field. In this paper, methods and technologies about how to test a SOS automatically are discussed in breadth and in depth at first.
