Question

A detection engineer has authored a new multi-event YARA-L rule in Google SecOps intended to detect credential dumping followed by lateral movement. Before enabling it for live alerting across production, the team wants to validate that the rule fires on known malicious activity without generating excessive noise, and they need evidence to support promoting it through their change-control process. Which approach best supports safe promotion of this rule into production alerting?

Accepted Answer

Run the rule in test/retrohunt mode against a historical window of production data to observe matches and false-positive volume before enabling live alerting

Answer

Immediately enable the rule with alerting on and monitor the SOC queue for the first week, disabling it if analysts complain

Answer

Deploy the rule with a very high match-window value so it only fires rarely, then lower the window gradually in production

Answer

Copy the rule logic into an ad-hoc UDM search once and, if it returns results, enable alerting permanently without further testing
