124+
Starting in MongoDB 5.3 Enterprise, you can use an external Key
125+
Management Interoperability Protocol (KMIP) server to securely manage
126+
the keys for encrypting the MongoDB audit log.
127+
128+
To use a KMIP server with audit log encryption, configure these settings
129+
and parameters:
130+
131+
- :setting:`auditLog.auditEncryptionKeyIdentifier` setting
132+
- :setting:`auditLog.compressionMode` setting
133+
- :parameter:`auditEncryptionHeaderMetadataFile` parameter
134+
- :parameter:`auditEncryptKeyWithKMIPGet` parameter
135+
136+
For testing audit log encryption, you can also use the
137+
:setting:`auditLog.localAuditKeyFile` setting.
138+
139+

142+
This section applies if you are not using an external Key Management
143+
Interoperability Protocol (KMIP) server to manage keys for encrypting
144+
the audit log as shown in the previous section.
145+
146+
The audit log file is not encrypted as a part of MongoDB's encrypted
147+
storage engine. A :binary:`~bin.mongod` running with :ref:`logging
148+
<monitoring-standard-loggging>` may output potentially sensitive

information to log files as a part of normal operations, depending on
150+
the configured :ref:`log verbosity <log-messages-configure-verbosity>`.

Use the :setting:`security.redactClientLogData` setting to prevent

potentially sensitive information from entering the

:binary:`~bin.mongod` process log.
155+
:setting:`~security.redactClientLogData` reduces detail in the log and
