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

process.name : "netsh.exe" and
process.args : ("firewall", "advfirewall") and process.args : "group=Network Discovery" and process.args : "enable=Yes"
