Hi
I want to drop all Windows Security Events (4624, 4625, etc) with Logon Type:3
My first idea is to make filter on my Heavy Forwarder:
props.conf
[WinEventLog:Security]
TRANSFORMS-windows_events = win-event-cut-en
[host::server1]
TRANSFORMS-security = events-null, drop_logtyp3, win
Maybe I must swap transforms (drop_logtyp3, win, events-null)?
transforms.conf
[events-null]
REGEX = .
DEST_KEY = queue
FORMAT = nullQueue
[win-event-cut-en]
DEST_KEY = _raw
REGEX = ((.*+[\v])+)(?=This event is generated)
FORMAT = $1
[win]
REGEX = (?msi)^EventCode=(4624|4625|528|529|530|531|532|533|534|535|536|537|538)
DEST_KEY = queue
FORMAT = indexQueue
[drop_logtyp3]
REGEX = (?msi).*Logon\sType:\s*3\D
DEST_KEY = queue
FORMAT = nullQueue
When I try my REGEX stanza in search, I get the correct result (no events with Logon Type:3):
host="server1" | regex _raw != (?msi).*Logon\sType:\s*3\D
But it does not work in transforms.conf.
Second idea is to use blacklist in the inputs.conf on my Universal Forwarder (ver 6.3.3 64bit) which installed on the server1, but I can't find any examples with regex in blacklist, only a simple list of eventcodes: blacklist = 4624, 4625
e.t.c.
Tell me please, where are my mistakes?
Hi,
I you just want to drop events with EventCode 4624, 4625, etc and Logon Type 3 from server1, why don't you simply get rid of those events with one transform and leave everything else? Your transforms look overcomplicated to me.
Try this and let me know:
[drop_logtyp3]
REGEX = (?msi)^EventCode=(4624|4625|528|529|530|531|532|533|534|535|536|537|538).*ComputerName=server1.*Logon\s+Type\s+3
DEST_KEY = queue
FORMAT = nullQueue
Unless you are trying to do something else, in which case the order is important. Read the props.conf specification in depth because it's an important and complicated topic.
If you want my advise, keep it simple initially and try to get your Logon Type 3 filtering working first, that is, only apply one transform at at time. Then apply others progressively.
Hope that helps,
J
