Investigation guide

edit
## Config

If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2, events will not define `event.ingested` and default fallback for EQL rules was not added until 8.2, so you will need to add a custom pipeline to populate `event.ingested` to @timestamp for this rule to work.

Rule query

edit
process where event.type in ("start", "process_started") and
(process.name : "appcmd.exe" or process.pe.original_file_name ==
"appcmd.exe") and process.args : "/dontLog*:*True" and not
process.parent.name : "iissetup.exe"
