The rule titled 'Snowflake Drop User' is designed to detect instances where a user is dropped from a Snowflake database account. It operates by querying the Snowflake account's usage logs, specifically accessing the `query_history` table. The detection logic checks the logs for drop_user events that have occurred within the last two hours, specifically looking for any queries that match the format 'drop user%'. This functionality is crucial for auditing purposes and ensuring compliance, as removing users can impact account access and permissions. The associated MITRE technique T1531 focuses on account access removal, aligning this detection with broader security monitoring efforts.
