windows_eventchannel or windows decoder editing

[TUKARAM GAONKAR]

Hi Team,

Currently wazuh decoding Source Network Address:2.2.3.4  as "data.win.eventdata.ipAddress".

Is it possible to change decoder field from "data.win.eventdata.ipAddress" to "data.srcip" .

Or

add one more decoding line with same regex used to decode " data.win.eventdata.ipAddress " but name is diffrent that is data.srcip .

So both field "data.srcip" and "data.win.eventdata.ipAddress" decoding with same IP.

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).

The Process Information fields indicate which account and process on the system requested the logon.

The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested."

Hi Tukaram

Thank you for using Wazuh and sharing your question with the community. I would like to know if you can provide me the log that was generated by the Wazuh agent and that has the field "data.win.eventdata.ipAddress". The field "data.srcip" that you want to parse with a decoder must appear in the log, if it does not appear then it will be impossible to create a new decoder to parse the log with the field.

Best regards

Hanes
