+##### Subject Naming Strategy
+
+The authorized subject naming strategy can be enforced at the namespace level.
+
+For Confluent Cloud clusters, if not specified, the strategy defaults to `TopicNameStrategy`. It can be configured in the `topicValidator` using the
+[`confluent.key.subject.name.strategy`](https://docs.confluent.io/platform/current/installation/configuration/topic-configs.html#confluent-key-subject-name-strategy)
+or [`confluent.value.subject.name.strategy`](https://docs.confluent.io/platform/current/installation/configuration/topic-configs.html#confluent-value-subject-name-strategy) properties, with one of the following values:
+- `TopicNameStrategy`: `<topic>-key` or `<topic>-value`
+- `RecordNameStrategy`: `<full_record_name>`
+- `TopicRecordNameStrategy`: `<topic>-<full_record_name>`
+
+For self-managed clusters, the strategy defaults to `TopicNameStrategy` and cannot be changed.
