Note, extra privileges may need to be granted to the samhain domain
if its default configuration file(/etc/samhainrc) is changed.
The samhain program could be used in the following way:
(In secadm_r role)
1. Initialize filesystem signature database:
newrole -l s15:c0.c1023 -p -- -c "samhain -t init"
(Note, the current secadm console will be blocked until
the database is completed)
2. Start samhain deamon to check filesystem integrity
newrole -l s15:c0.c1023 -p -- -c "samhain -t check -D"
3. Update filesystem signature database:
newrole -l s15:c0.c1023 -p -- -c "samhain -t update"
(In sysadm_r role)
1. Start samhain in daemon mode:
run_init /etc/init.d/samhain start
2. Stop samhain daemon:
run_init /etc/init.d/samhain stop
3. Check samhain daemon status:
run_init /etc/init.d/samhain status
4. Read/write samhain log files:
newrole -l s15:c0.c1023 -p -- -c "cat /var/log/samhain_log"
5. Remove samhain database files
newrole -l s15:c0.c1023 -p -- -c "rm /var/lib/samhain/samhain_file"
Note:
1. Stop samhain daemon before updating signature database.
2. Don't try to start samhain daemon twice.
3. Need to toggle SELinux into the Permissive mode in order to remove
the samhain_log files from /var/log/.
