changing /cn@0:console file permissions
I'm doing a security sweep of a Sun Sol 5.8 system. The file: /dev/console, which links to /devices/pseudo/cn@0:console, has the following perms: crw--w--w- I would like to get rid of the world write permissions. I can change the file permissions, but as soon as log back in, they are changed back to the original settings. Any one have any ideas of what is causing this? Thanks.

NAME
pam_console_apply - set or revoke permissions for users at the system console
SYNOPSIS
pam_console_apply [-r]
DESCRIPTION
pam_console_apply sets or resets permissions on devices in the same manner as pam_console.
If /var/run/console.lock exists, pam_console_apply will grant permissions to the user listed therein. If the lock file does not exist,
permissions are reset to those listed in /etc/security/console.perms, which should be configured to set permissions on devices so that root
owns them.
ARGUMENTS
-r Signals pam_console_apply to reset permissions. The default is to set permissions so that the user listed in /var/run/console.lock
has access to the devices, and to reset permissions if no such file exists.
FILES
/var/run/console.lock
/etc/security/console.perms
