Hi, I am trying to use the custom command to read the data from other database and return to Splunk as query results. I understand that a custom command can be developed in python script and I'm thinking that python script can read the data from the database and return to Splunk.  I have few questions here:  When we execute the custom search command in Splunk search GUI - does custom search command requests goes to Indexer?  In other words, do I need the indexers when i just run only the custom search command in my Splunk distributed environment? The custom search command had to retrieve lots of data from database. So, the custom search can be used for large volume of databases and performance issues can be anticipated for custom search commands?  How Splunk handles the custom search commands in backend - when there are multiple users execute the custom search command - Splunk executes the python script in the same thread (or) in different thread per user search request?   Thanks ...

Hi, SSE use case maps to the MITRE ATT&CK tactics. As we can see from MITRE ATT&CK, each tactic has various techniques. For "Data Exfiltration" , the techniques are "Data Transfer Size Limits" , "Exfil over Alternate Protocol" etc. For example: In SSE, the example "Sources Sending a High Volume of DNS Traffic" mapped to MITRE ATT&CK's DataExfiltration. Splunk reports outliers. How do I know which technique splunk used to determine the outlier? Or Splunk doesn't use any of these techniques , it just uses the total bytes transferred and looking for anomalies and deviations from normal traffic levels.? Thanks, Mahesh ... View more
