TMA-TDSQL-10.1

Ensure SSL Is Enabled on the Replication Link

AltaNivel 1Automatizadatdsql

Descripción

The data stream of MySQL primary-replica replication should be encrypted with SSL to prevent replication data from being eavesdropped on the network. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Run on replicas: passes when every replication channel shows Master_SSL_Allowed: Yes. A node that is not a replica (empty SHOW REPLICA STATUS) passes because it has no inbound replication link.

Cómo se verifica

Método de auditoría: Consulta SQL

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -e 'SHOW REPLICA STATUS\G' 2>/dev/null) || exit 1; if [ -z "$out" ]; then echo compliant; else n=$(printf '%s\n' "$out" | grep -c 'Master_SSL_Allowed: Yes' || true); t=$(printf '%s\n' "$out" | grep -c 'Master_SSL_Allowed:' || true); [ "$t" -gt 0 ] && [ "$n" -eq "$t" ] && echo compliant || echo noncompliant; fi

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Configure replication SSL through the TDSQL management platform (inter-component SSL, 9.2), or STOP REPLICA; CHANGE REPLICATION SOURCE TO SOURCE_SSL = 1, SOURCE_SSL_CA = ...; START REPLICA;
