"Host" field

Jump to solution

Dear community,

What should be the value of the "host" field used for ?

The reason why I am asking such "basic" question is that:

1. No document described the mapping the fields, does McAfee have any document explaining it ?

2. For the same event ID 4624 (Windows) ntlm/kerberos/microsoft authentication package the field mapping is changed

Case 1 - kerberos

FieldValue
Host<fqdn(hostname.domain)>
Source_IP<Datasource IP> or 127.0.0.1
Destination_IP<Datasource IP>
Source_User<Hostname$>
Destination_User<empty>
Logon_Type3 - Network
Objectkerberos

Case 2 - Authentication package

FieldValue
Host<hostname>
Source_IP<Client IP>
Destination_IP<Datasource IP>
Source_User<username>
Destination_User<empty>
Logon_Type3 - Network
Objectmicrosoft_authentication_package_v1_0

Case 3 - NTLM

FieldValue
Host<Client hostname>
Source_IP<Client IP>
Destination_IP<Datasource IP>
Source_User<Client hostname$>
Destination_User<empty>
Logon_Type3 - Network
Objectntlm

* The same applies when using Windows Event Forwarding.

** Even between built-in and ASP parser there are some differences with the mapping to the custom fields.

Thank you for your help

Got an answer from McAfee...

They do not know either what it is supposed to be (lol) and admit that the fields is set to different values depending on the log type. (e.g the host field should be set to the datasource name unless it is a connection event were it is populated with the hostname of the client which connected.)

I will eventually log a PER to transform this field into 3 different fields:

- datasource_host

- source_host

- destination_host

But again I doubt it will be pushed to the product...
