The checksecurity.conf file defines several configuration variables: MAILTO,CHECK_DISKFREE, CHECK_PASSWD
and CHECK_SETUIDLOGDIR. Each is described below.
The checksecurity program works with a collection of plugins which are located in
/usr/share/checksecurity and are configured individually by their own configuration file.
CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked. This script is
designed to report upon system accounts which have no passwords. CHECK_DISKFREE If this is set to TRUE
then the check-diskfree script will be invoked and will allow an alert to be sent if there is any mounted
partition is running short on disk space. CHECK_SETUID If this is set to TRUE then the check-setuid
script will be invoked, this will compare the setuid binaries upon the system to those that existed
previously and show the differences.
