Properties
The configurable properties are listed as follows:
priv_user_list
A list of system-level user IDs or user names.
This list contains users that have elevated access to the
system. Removing any of these users means that this
template does not detect the creation of a world-writable
file owned by that users.
pathnames_to_not_watch
Path names of files that can be safely ignored if they are
made world writable.
pathnames_X, programs_X
Filter out alerts generated when a specified program creates
a specified world-writable file. See “Type II: Path
Names/Programs Pairs” (page 116) for a detailed description
of these property pairs.
