  • Selective logging of Windows Event Log fields when forwarding to SIEM - exclude information text from the end of the log message | nxlog.co
    not always available and may be left blank in some cases The impersonation level field indicates the extent to which a process in the logon session can impersonate The authentication information fields provide detailed information about this specific logon request Logon GUID is a unique identifier that can be used to correlate this event with a KDC event 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 35284558 My issue is that I would NOT want to collect the informational text representing the event in this case everything starting from the string This event is generated all the way up until was requested Before I go any deeper into this let me state that in the logs of this format I call the 14 Jan 27 10 03 39 event computer MSWinEventLog 1 Security 32630749 Wed Jan 27 10 03 39 2016 4624 Microsoft Windows Security Auditing N A N A Success Audit event computer Logon portion of the whole log message the HEADER and the rest is called MESSAGE Putting it another way I would like to forward the message using syslog in a format constructed according to the pseudocode below parse fields from windows event e g SubjectUserName LogonType IpAddress etc print the header as is already in the to syslog snare format i e from 14 until and including Logon print HEADER e g event time event computer event type event id for all fields parsed print field name field value e g SubjectUserName value LogonType value IpAddress value The reason I would like to do this is that the informational text which gets appended to some Windows events not all it seems takes a lot of space and we do not really need this information text for anything Another way to do this would be to statically list all the fields POSSIBLY found in an Windows event and construct the message that way but this would often leave me with a lot of empty key value pairs THUS I would only like to print out those fields that were found in that specific log message while leaving out the informational message I do acknowledge though that especially Application and System events might not contain most or any of the fields that are present in a Security log event Take for example the following System log event 14 Jan 27 11 09 21 event computer MSWinEventLog 1 System 32633951 Wed Jan 27 11 09 21 2016 7036 Service Control Manager N A N A Information event computer N A The Remote Registry service entered the stopped state 319889 In the example above the header portion of the whole message only contains the string The Remote Registry service entered the stopped state I do hope though that the variable where this string is
