12. Checking mounted filesystem policies

To compile with support for this option, use the configure option

./configure --enable-mounts-check

samhain can be compiled to check if certain filesystems are mounted, and if they are mounted with the appropriate options. This module currently supports Linux, Solaris, HP-UX (mount options as in /etc/mnttab), and FreeBSD. The configuration of the module is done in the Mounts section of the configuration file:

	# Activate (default is no).
	MountCheckActive = yes
	# Interval between checks (default = one day).
	# Logging severities. We have two checks: 
	# 1) to see if a mount is there (default = err), and 
	# 2) to see if it is mounted with the correct options (default = err).
	# Mounts to check for, (optionally) followed by lists of 
	# mount options to check on them.
	checkmount=/tmp noexec,nosuid,nodev 
	checkmount=/home noexec,nosuid,nodev
