Description
The principle of Least Privilege ordinarily requires analysis to ensure that users and processes are granted only as much privilege as is required to function effectively, but no additional privileges that could enable mischief, either accidental or intentional. The Pubic Virtual Server enables web access to public folder documents via browser. This control determines whether users will have read, write, script source access, and/or directory browsing capabilities under this virtual server. Public Virtual Server requires that users have read, write, script source access, and directory browsing permissions since these are required for proper functioning Public Folders access.
