Hi Ed,
A couple things that might help here. When you enable logall, you’ll want to
look inside archives.log, not alerts.log. Assuming this wasn’t a typo, here’s a
few things that might help with your problem:

what I understand, 2.8.x had trouble with this and therefore had trouble with
sysmon. Has that been your experience with 2.8.3? Thanks again everyone for the
help.

Craig,
Hm... I just now noticed your exact symptoms while playing with a test OSSEC
server that was created from a relatively recent git clone of the repository
(cloned within the last month or two?). Take a look at your original output of
ossec-logtest, under “Prepended Data Removed”. Look
Delving into Sysmon event log parsing reveals just how monumental a task it is
to parse out useful information from Windows event logs. The challenge is that
nearly each and every Event ID has a different log format, which essentially
means that almost every Event ID needs its own decoder... I

It is also worth noting that you may possibly be misunderstanding how

not the metadata of where the log came from. So if the string “ip_address”

Have you run your log entry through ossec-logtest on the server? This will tell
you if an alert should be generated or not. It is always possible that another
rule is matching first or perhaps your rule isn’t working as expected. There

You may very well have to download the latest rule files from the github

by copy/pasting a line from your apache log into ossec-logtest and seeing if it
knows how to decode it.

OSSEC on the server with the client keys shows the same permissions as my local

Hi lostinthetubez,
Yes, the client.keys file exists on the server and the client has the correct
key. The permissions are as follows for /var/ossec/etc
Looks like permissions or ownership are wrong on your client.keys file, which
would certainly explain the agent not being able to connect. I assume you’ve
checked that the client.keys file exists and contains the correct information
for the agent you are using as an example here?
