See the description of the GRANT statement in Teradata Vantage™ - SQL Data Control Language, B035-1149, for an explanation of the types of privileges, and how they are granted.
If a more detailed audit trail is necessary, this information may be supplemented by log entries that provide an audit trail of the results of checks against requests to access table data. See Teradata Vantage™ - Advanced SQL Engine Security Administration, B035-1100.
