Ensure the default password is changed for the yugabyte superuser

クリティカルレベル 1自動yugabytedb

説明

The yugabyte role is the built-in YSQL superuser in YugabyteDB. By default, it has a well-known password. This default password must be changed before the cluster is deployed to a non-development environment. Leaving the default password in place allows anyone with knowledge of the default to gain full superuser access to all databases in the cluster. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Attempts a ysqlsh login as yugabyte with the default password against PGHOST/PGPORT (default 127.0.0.1:5433); passes only when the login is rejected with an authentication error. A successful login (including trust authentication) fails, an unreachable server fails.

ALTER ROLE yugabyte WITH PASSWORD '<new strong password>'; store it in a password vault, and make sure ysql_enable_auth=true (5.6).
