»Socket Audit Device
socket audit device writes to a TCP, UDP, or UNIX socket.
Warning: The loss of audit logs may occur when using the UDP socket audit type. Because UDP socket audit type is connectionless, meaning the UDP endpoint becomes unavailable, it’s possible that any number of audit logs written to it may get lost, even though the request will still succeed. Vault does not provide an indication for the loss of audit logs. Therefore, we recommend using your device in conjunction with a secondary “non-socket” audit device to ensure accuracy and to guarantee that audit logs will not be lost.
Warning: When using a TCP socket audit type, and connection loss to the socket occurs, a single audit entry may be omitted from the audit entry. The request from the TCP socket audit type will succeed despite the omission of the audit entry.
Enable at the default path:
$ vault audit enable socket
Supply configuration parameters via K=V pairs:
$ vault audit enable socket address=127.0.0.1:9090 socket_type=tcp
socket audit device supports the common configuration options documented on
the main Audit Devices page, and
these device-specific options:
(string: "")- The socket server address to use. Example
(string: "tcp")- The socket type to use, any type compatible with net.Dial is acceptable. It's important to note if TCP is used and the destination socket becomes unavailable Vault may become unresponsive per Blocked Audit Devices.
