setuid/setgid template will not detect the creation of a
setuid file owned by one of those users.
priv_group_list A list of system-level group IDs or group names.
This list contains those groups who have elevated access to
the system. Removing any of these groups from this list
means that the setuid/setgid template will not detect the
creation of a setgid file owned by one of those groups.
pathnames_X, programs_X
Filter out alerts generated when a specified program creates,
modifies, or enables a specified privileged setuid file. See
“Type II: Path Names/Programs Pairs” (page 116) for a
detailed description of these property pairs.
Alerts generated by this template
Setuid or setgid File Created or Modified
Table A-16 lists the alert properties the setuid/setgid template generates and forwards to a
