  1. Event logs Audit Failure tracking


    Hi guys,Today when i was inspecting security event logs at active directory server i realised we are recieving constant password brute force attacks from different user accounts.Usernames were seeming to be coming from a rainbow table as; Jessie, Jaxon, Clare...so onSource workstation is also seeming to be different on each try as; Windows7, Remmina, Windows2019, Windows10, FreeRDP...The question is i have no identifier to reach an ip address to reach the attacker device.I am adding an example log output and info i got, and i need guidance to reach further information on which device is sendi

  2. Security Audit Failure Event 5061 In Windows 10

    Hello,

    A failure audit event is triggered when a defined action, such as a user logon, is not completed successfully.

    The appearance of failure audit events in the event log does not necessarily mean that something is wrong with your system. For example, if you configure Audit Logon events, a failure event may simply mean that a user mistyped his or her password.

  3. Unexpected Audit Failure in Event Viewer

    I did make some progress in that I can disable the Audit Failure from being logged with the Event Viewer.

    Go to Command Promp (Admin) and enter:

    auditpol /set /subcategory:”Filtering Platform Connection” /success:disable /failure:disable

    Caveat: Someone posted that the Audit Failure will likely return the next day.

    Plus this is tantamount to replacing a fuse without fixing the underlying problem which is causing the fuse to blow.

    Still hoping an Event Viewer / "Filtering Platform Connection" guru will chime in.

    Event logs Audit Failure tracking

    Audit failures every reboot - Event 5061 - Cryptographic operation.

    Before I upgrade my 10 to the Spring version, I did some more digging.

    I looked at the sequence of Audit Successes before and after each Audit Failure - maybe they're related? Maybe the steps mean something? In the link below, I have pasted the "General" subwindows for the Event Viewer events closely preceding, including and following each of the two Audit Failures in my most recent bootup.

    There seems to be some kind of pattern of the machine looking at the key, DELETING it, then looking for it again, then throwing the AUDIT FAILURE - maybe because it just deleted the key and the key isn't there any more - and then re-creating the key. Is the AUDIT FAILURE just the good result of a test that the key was successfully deleted?

    But WHY is the machine doing this? Why delete and recreate? What's really going on?

    Here's the link to the Word Online document in which I've pasted both Event Viewer sequences:
    <THIS LINK>


    Any thoughts? (And am I interpreting the events correctly anyway?)
