The rule 'Snowflake Create Role' monitors the execution of CREATE ROLE statements within the Snowflake database. It specifically checks the account usage query history to identify any role creation attempts made in the last two hours. The logic utilizes SQL syntax to filter the query history with conditions to capture events that match 'create_role' in their signature and contain 'create' and 'role' in the query string. This monitoring aids in detecting unauthorized role creation that may indicate account manipulation or privilege escalation attempts. Given its focus on role management, this rule is vital for maintaining access controls within Snowflake environments and ensuring compliance with security policies.
