Is ossec reading my IIS logs?

[Steve West]

Hi,

How do I test if ossec is actually reading the IIS logs I setup in
ossec.conf? I don't see any entries in the ossec.log stating anything
about iis logs and I'm wondering if there is a way I can test to make
sure ossec is actually reading the logs.

Also, can ossec take active response on the windows side?

Here is the iis logs section in my ossec.conf:

<localfile>
<location>E:\hslogfiles\www\W3SVC1\ex%y%m%d.log</location>
<log_format>iis</log_format>
</localfile>

<localfile>
<location>E:\hslogfiles\www\W3SVC3\ex%y%m%d.log</location>
<log_format>iis</log_format>
</localfile>

<localfile>
<location>E:\hslogfiles\www\W3SVC4\ex%y%m%d.log</location>
<log_format>iis</log_format>
</localfile>

thx,

SW

Steve,
My windows installation (ossec 1.1) displays the following in the
ossec.log:
2006/10/11 12:00:19 ossec-agent(1952): Monitoring variable log file:
'C:\WINNT\System32\LogFiles\W3SVC1\ex061011.log'.

Your ossec.conf entries look good to me. Have you configured IIS to log
all of the parameters to the file?

Hi Rick,

Yes, all options under Logging Properties has been enabled. I don't see
any mention of any of the iis virtual sites in ossec.log.

Here is a sample iis web site log entries:

Hi Steve,

Did you restart the agent after adding the iis logs? Can you show us your
agent ossec.log? Something must in there....

Thanks,

Hi Daniel,

Yes, I've restarted the agent each time I made any changes to the agent
ossec.conf file and still can't see anything in there relating to iis
virtual hosts.

I've enclosed the agent ossec.log and also my ossec.conf agent
configuration.

BTW, this is on a w2k3 server if I didn't mention it before using ossec 1.2.

Thanks for all your help,

SW
