Problem with watching power commands - key is not logged

Problem with watching power commands - key is not logged

Hi

 

I'm struggling to get proper auditing of usage of power commands, here's
what I've got in rules

 

[root@host01 ~]# cat /etc/audit/audit.rules | grep power

-w /sbin/shutdown -p rwx -k power

-w /sbin/poweroff -p rwx -k power

-w /sbin/reboot -p rwx -k power

-w /sbin/halt -p rwx -k power

-w shutdown -p rwx -k power

-w poweroff -p rwx -k power

-w reboot -p rwx -k power

-w halt -p rwx -k power

 

However despite full host reboot/refreshing rules I'm not getting events
with proper key "power"

 

[root@host01 ~]# cat /var/log/audit/audit.log | grep power

<empty>

 

Events are logged though but without key

 

type=USER_CMD msg=audit(1485604576.755:679): pid=3490 uid=5004 auid=5004
ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
msg='cwd="/home/user01" cmd="reboot" terminal=pts/0 res=success'

type=USER_CMD msg=audit(1485604729.923:658): pid=3428 uid=5004 auid=5004
ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
msg='cwd="/home/user01" cmd="reboot" terminal=pts/0 res=success'

 

Any idea what is wrong? Rules with other keys seems to work.

I suspect you have another rule that is catching it first?

I found it out
auditctl -l did not list rule as loaded, I checked logs of auditd deeper
and found it stopped loading rules at some point due to duplicated rule,
after sorting that out, it loaded all rules correctly, sorry for trouble

Glad to hear that it's working for you now.

Typically, the '-w <path/filename>' syntax is to watch system files for
modification, not so much to audit the execution of the command (like for
power events, as you're doing). The way I audit reboot commands (among
others) is:

-a always,exit -F arch=b32 -S acct -S reboot -S sched_setparam -S
sched_setscheduler -S setrlimit -S swapon -k reboot_sched_swap
-a always,exit -F arch=b64 -S acct -S reboot -S sched_setparam -S
sched_setscheduler -S setrlimit -S swapon -k reboot_sched_swap
and
-w /var/run/utmp -p wa -k session

This might not be sufficient for your needs, but hopefully it's helpful.
