The Snowflake Successful Login detection rule is designed to monitor and track successful login attempts within the Snowflake environment. This rule utilizes login history logs from Snowflake to identify entries that indicate a successful authentication event. Each login event is processed to extract relevant details such as user credentials used, client information, and login success statuses. If a login event indicates success (identified by the 'IS_SUCCESS' field set to 'YES'), the event is recorded for potential correlation with other security events. This allows security teams to build a timeline of events and correlate user access with other activities, contributing to an improved security posture. The detection is set at an informational severity level, meaning it primarily serves to log successful access for review rather than generating alerts for immediate action. The rule is not intended to create alerts, indicating that it should be used strictly for auditing and monitoring purposes.
