Adding my 2c to this thread since I've found it be so very useful: 1. The ePO to splunk TLS connection requires only a splunk-side cert. I've used a self-signed cert by doing the following: 1.a.  sudo openssl req -x509 -days 3650 -nodes -newkey rsa:2048 -keyout splunk-epo-remote.key -out splunk-epo-remote.crt 1.b. cat  splunk-epo-remote.crt  splunk-epo-remote.key >  splunk-epo-remote.pem 2. the [SSL] stanza in input.conf is: serverCert=/opt/splunk/certs/ splunk-epo-remote.pem requireClientCert=false   I've also updated the ciperSuite based on this link https://community.splunk.com/t5/Getting-Data-In/how-to-configure-Mcafee-Epo-to-send-data-to-Splunk/m-p/532241 to add the AES256-GCM-SHA384 cipher     ...

@indeed_2000 , What system/app is generating this logs ? did you try to find a TA on Splunkbase for it ? At any rate, based on the logs you attached, this is what I came up with :   | rex "\-(?<id>\d+)\s*(\[|\_).*\-(?<id2>\d+)\s*(\[|\_)" | rex "(?<State>(Receive|Send|Received|Processed))(\s+Message|\:)" | transaction id startswith=(State=Received) endswith=(State=Send) ...

Hi @splunkerer , With your permission I'll start from the beginning, with your problem statement. You wrote that "if login attempt get failed, userid doesn't show up" and "userid is supposed to be unique, but not always".  So how do you link between the failed login events and the following successful one ? by host name or some id ? If possible can you share some sample dataset from your dev/QA environment or something similar ?   ... View more

Hi @itssuresh07 ,   I assume that when you run the first part of the query you do get the 4624 and 4688 Events, right ? If so, it might be that the maxspan or maxpause options were changed to very small defaults (like 1s). Try to explicitly declare no limits: | transaction Logon_ID host startswith=(EventCode=4624) endswith=(EventCode=4688) maxspan=-1 maxpause=-1   See the docs at https://docs.splunk.com/Documentation/Splunk/8.2.1/SearchReference/Transaction  ...

Hi @kronite13 , You don't necessarily need to end up with 3,000 regexes but I think you will have to have some kind of reference to the exposed api endpoint that you then need to import, possibly into a multivalue field and check for the similarity in order to do the grouping you wish to do.   Hope this help. ...

The way we are doing it (obviously there is always a better way 😀😞 Make a list of all the apps on your current system and their version Backup all the apps folders (so that local, appserver and  the rest will be backed up as well !) Make a record of any in-house developed app that is using scripting or any external resource you are aware about Head over to splunkbase to check if the app is supported in the version you are upgrading to For every app check see if there was an update from the version you listed in (1). Some apps that will now support the splunk version you are upgrading to will change their inner working handle any conflicts or issues on dev/QA instance based on your own processes before you move to production. Good luck ! Good luck !  ... View more
