Question

System administration

Colleagues, good afternoon
There are a large number of services that have domain authorization
in the logs, you can see brute force in AD, but it is not clear to which resource
Failed Logon,"Logon","N/A","dc-104.local","ADMINISTRADOR", "07/29/2018 3:28:48 AM","N/A","Cause: User logon with misspelled or bad user account."
Failed Logon,"Logon","N/A","dc-102.local","ADMINSVR","7/29/2018 3:28:49 AM","N/A","Cause: User logon with misspelled or bad user account."
How can I find out the IP address of this hacker?)

Answer 1

Set up an edge server for authorization and catch the scoundrel on it. As an example, you can use ForeFront TMG. or compare authorization time with firewall logs

Answer 2

Wireshark with filter is our everything...
