Hello Splunk Community, History of problem: I recently was trying to update OSSEC agents and some needed to be reinstalled to be fixed. So in my plan of action for targeting, the main OSSEC server got targeted and reinstalled as an agent instead, thus having me to reconfigure everything becauase we did not have a backup. After a weekend of configuration recovery, all 100+ agents got reconnected and authenticated with new keys and updated configs for both the server and agents. Everything is connected and communicating, reporting alerts to the alerts.log, local_rules.xml file is updated. We use Splunk Forwarder to forward the logs and we get log information, but it looks like it's not being processed correctly....this is our issue. Problem and End-Result Needed: Splunk is receiving information from OSSEC server but the data is having trouble being processed by the IDS data model. Splunk field for Log "sourcetype" seems to be the root of the issue. We need to have Datamodels process this information or have the Splunk OSSEC add-on properly configured because we have the path on the splunk server, but not fully configured: /opt/splunk/etc/apps/Splunk_TA_ossec/ What we noticed in Splunk search: Before Sourcetype=alerts Current needing fix Sourcetype=alerts-4 and Sourcetype=alerts-5 IDS (Intrusion Detection) Splunk data model needs to process logs by severity and update the dashboard accordingly Splunk Add-on is not properly configured Some pictures are attached of the issue. --------------------- Resources --------------------- https://docs.splunk.com/Documentation/AddOns/released/OSSEC/Setup https://docs.splunk.com/Documentation/CIM/5.0.1/User/IntrusionDetection https://docs.splunk.com/Documentation/AddOns/released/OSSEC/Sourcetypes ...
