Introduction


Chapter 9, "UNIX I: Privileges and Files," introduced the essential concepts of how UNIX OSs provide security. This chapter extends the discussion of UNIX by focusing on the security of UNIX processes and the environment in which they run. You will learn how to evaluate the security implications of how a process is invoked, as well as the security-relevant considerations of the process environment. You will also see how small changes in process behavior can have a major impact that manifests as exploitable privilege-escalation vulnerabilities. This coverage will provide you with the understanding necessary to audit a UNIX application for vulnerabilities that exist when the process environment is not adequately protected.
