GIAC GCFA Question Answer
John works as a Network Administrator for DigiNet Inc. He wants to investigate failed logon attempts to a network. He uses Log Parser to detail out the failed logons over a specific time frame. He uses the following commands and query to list all failed logons on a specific date:
logparser.exe file:FailedLogons.sql -i:EVT -o:datagrid
SELECT
timegenerated AS LogonTime,
extract_token(strings, 0, '|') AS UserName
FROM Security
WHERE EventID IN (529;
530;
531;
532;
533;
534;
535;
537;
539)
AND to_string(timegenerated,'yyyy-MM-dd HH:mm:ss') like '2004-09%'
After investigation, John concludes that two logon attempts were made by using an expired account.
Which of the following EventID refers to this failed logon?
