Native tools and PowerShell scripts demand expertise and time when employed to this end, and so a third-party tool is truly indispensable.Īpplying machine learning, ADAudit Plus creates a baseline of normal activities specific to each user and only notifies security personnel when there is a deviation from this norm.įor example, a user who consistently accesses a critical server outside of business hours wouldn't trigger a false positive alert because that behavior is typical for that user. Thus, event analysis and correlation needs to be done.
To find the logon duration, you have to correlate Event 4624 with the corresponding Event 4647 using the Logon ID. In a typical IT environment, the number of events with ID 4624 (successful logons) can run into the thousands per day. However, all these successful logon events are not important even the important events are useless in isolation, without any connection established with other events.įor example, while Event 4624 is generated when an account logs on and Event 4647 is generated when an account logs off, neither of these events reveal the duration of the logon session. The Authentication Information reveals information about the authentication package used for logon.If the logon was initiated from the same computer, this information will either be blank or reflect the local computer's workstation name and source network address. The Network Information section reveals where the user was when they logged on.The Process Information section reveals details surrounding the process that attempted the logon.The Impersonation Level section reveals the extent to which a process in the logon session can impersonate a client. Impersonation Levels determine the operations a server can perform in the client's context.The Subject section reveals the account on the local system (not the user) that requested the logon.Other information that can be obtained from Event 4624:
the domain controller was not contacted to verify the credentials). Occurs when a user logs on to their computer using network credentials that were stored locally on the computer (i.e.
