I have windows security event filter setup and working on my indexer. However I want to filter on three variables.
The logic is as follows: Keep all events, except the ones that match the regex.
My current filter looks like this:
REGEX = (?msi)^EventCode=(123|678|910).*^(User=userxxx)
DEST_KEY = queue
FORMAT = nullQueue
I want to add one more variable to the filter (Type=Success Audit).
Also, in the future I may want to add a hostname to this regex, so that it only filters out these events on a certain host, so once host name is added it would be filtering on 4 variables.
This works like a charm.
#Exclude Sample User Authentication Events [nullFilter-user1] REGEX=(?ism)EventCode\s*=\s*(123|456|789).*User\s*=\s*user DEST_KEY=queue FORMAT=nullQueue
I do this to filter out all sorts of things. 🙂
What would be syntax for adding to the regex. I've only seen examples of addting two variables to a regex, not three or four.
Do you need to filter these independently or dependently? i.e. must we match the eventcode, type and user and host? or is it some combination, i.e eventcode+host or eventcode+user? for the former, just add to your regex, for the later, add multiple stanzas.
