Abstract

This paper describes UNIXvisual, which helps students learn access control in UNIX. UNIXvisual is aimed both at novice users, who need only to control access to their own files, and students of computer security, who need a deeper and more comprehensive understanding. UNIXvisual allows students to analyze permission settings without the need for a special environment. It allows a student to trace the value and effect of credentials within an executing process. It also provides a mechanism for instructors to give quizzes UNIXvisual gives instructors flexibility in covering the material by supporting self-study, lowers the overhead required for teaching access control by running under an ordinary user account, and enhances learning by leveraging visualization. UNIXvisual is available for download and runs on the Linux and MacOS platforms.
