PostgreSQL
TMA-POSTGRES-4.9
Make use of predefined roles
Descripción
PostgreSQL provides a set of predefined roles that provide access to certain commonly needed privileged capabilities and information. Administrators can GRANT these roles to users and/or other roles in their environment, providing those users with access to the specified capabilities and information.
Cómo se verifica
Método de auditoría: Revisión manual
Run SELECT rolname FROM pg_roles WHERE rolsuper IS TRUE; and, for each superuser other than the bootstrap account, decide whether predefined roles (pg_read_all_data, pg_write_all_data, pg_monitor, pg_signal_backend, pg_checkpoint, pg_maintain, ...) would suffice. Unneeded superusers are a fail.
Cómo se corrige
Método de corrección: Guía o parche de infraestructura
GRANT the suitable predefined role(s) to the account, then ALTER ROLE <role> NOSUPERUSER;
