when executing <program>
(type=<type>, inode=<inode>,

process with pid <pid> and ppid
<ppid> and running with effective

NOTE: See Table B-1 (page 161) for the definition of additional arguments that can be used to
access specific alert information (for example, pid and ppid) without parsing the string alert
fields.
Limitations
The setuid/setgid file template has the following limitations:
• The template cannot always distinguish whether a setuid (or setgid) file is created and
whether an existing setuid (or setgid) file is opened for modification with the create flag.
The template can generate an alert that a setuid (or setgid) file was created rather than
generating an alert that a setuid (or setgid) file was opened for modification. The template
can also generate a false alert that a setuid (or setgid) file is created even though the file
already exists, and is opened with the create flag rather than for modification.
• The template cannot always distinguish whether a setuid (or setgid) file is created, and
whether an existing setuid (or setgid) file is truncated. The template can generate an
alert that a setuid (or setgid) file is created, instead of generating an alert that a setuid
(or setgid) file is truncated.
