+To enable log redaction in TiCDC, set [`security.redact-info-log`](/ticdc/ticdc-server-config.md#redact-info-log-new-in-v856) to `true` in the TiCDC server configuration file. This parameter defaults to `false`, which means that log redaction is disabled. When you set it to `true`, TiCDC replaces sensitive values in logs with `?`. Alternatively, set it to `"marker"` to enclose sensitive values in `‹` and `›` while preserving their original values.
