Ensure excessive DML privileges are revoked
Descrição
DML (insert, update, delete) operations at the table level should be restricted to only authorized users. YugabyteDB manages table-level DML permissions via the GRANT statement.
Como é verificado
Método de auditoria: Revisão manual
In each database list users (\du+ *) and tables (\dt *.*) and review table grants (\dp or information_schema.role_table_grants). Any user holding INSERT, UPDATE, DELETE or TRUNCATE on tables it does not need for its role is a finding; revoke with REVOKE <priv> ON <table> FROM <user>.
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
If a given database user has been granted excessive DML privileges for a given database table, those privileges should be revoked immediately using the REVOKE YSQL command. Continuing with the example above, remove unauthorized grants for appreader user using the REVOKE statement and verify the Boolean values are now false. yugabyte=# REVOKE INSERT, UPDATE, DELETE ON TABLE customer FROM appreader;
