Configure directory permissions as follows:
There are no directories that have the other Write permission bit set on without the sticky bit set on.
NOTE: In the symbolic permission bit display, the sticky bit is indicated as a "t" or "T" in the execute portion of the other permissions. For example, a display of the permissions of a directory with the sticky bit on could be "drwxrwxrwt".
All directories that have the other write permission bit set on do not contain any files with the setuid bit set on.
