How to deploy on Sigma
- 1.Convert for your SIEM with sigma-cli / pySigma, e.g. sigma convert -t splunk -p sysmon rule.yml.
- 2.Run it as a hunt first: every rule ships as status experimental.
- 3.Promote to an alert once a week of results is clean on your data.
Check · The processing pipeline must map the logsource (firewall, dns, proxy, webserver, process_creation) to your field names.
