The Snowflake Grant Ownership rule helps detect events in which ownership of database objects, typically defined by schemas, is transferred from one role to another within a Snowflake account. Such ownership transfers are critical as they can potentially change access controls significantly. The rule specifically looks for SQL commands that indicate ownership changes, utilizing the Snowflake query history table to identify 'GRANT OWNERSHIP' statements executed in the last two hours. The execution of this command could signify an elevation of privileges or unauthorized changes in user roles that might pose security risks. Through monitoring these changes, analysts can be alerted to potentially suspicious activity that aligns with account manipulation techniques, categorized under persistence tactics used by attackers. If a legitimate role is executed, it may need further investigation to ensure that it adheres to company policy and access control protocols.
