Like most operating systems in the last 40 years, Unix uses a hierarchical "tree-structured" file system (interestingly, tree-structure and other aspects of the Unix file system are a direct result of the original Unix developers being influenced by the Multics project they had been working on). Directories contain files and subdirectories which, may in turn, contain other files and subdirectories, and so on. | Unix for Security Professionals Security Essentials The SANS Institute Unix Security - SANS 2001 1 All material in this course Copyright Hal Pomeranz and Deer Run Associates 2000-2001.
