I have the same question Report abuse. Details required :. Cancel Submit. Marilou Ser Microsoft Agent. Hello, For further assistance, can you be more specific about Audit Success logs?
Keep us posted. How satisfied are you with this reply? The subcategory setting will take over on Windows systems. Subcategories cannot be set on earlier Windows versions, so only policy categories are effective on legacy systems. This complex hierarchy of setting priorities can yield unintended results. Just make sure that Group Policy has already been applied when you use Auditpol.
Group Policy might take some time to replicate and to be applied after a change. Microsoft should have named the Audit account logon events policy Audit authentication events. On DCs, this policy records attempts to access the DC only. The policy does not, for example, track a user who uses a domain account to log on at a workstation. But to track all domain account authentication, you should use the Audit account logon events policy.
As you can see, some of these subcategories have nothing to do with logons or logoffs. The Audit process tracking policy records events in the Detailed Tracking category. You can even determine how long the program was open. The Audit object access policy handles auditing access to all objects that reside outside of AD.
The first use you might think of for this policy is file and folder auditing. You can also use the policy to audit access to any type of Windows object, including registry keys, printers, and services. Furthermore, to audit access to an object such as a crucial file, you must enable more than just this policy; you must also enable auditing for the specific objects that you want to track.
However, be warned: This policy can bog down servers. Audit only crucial objects and audit only for crucial access e. The Audit account management policy, which you can use to monitor changes to user accounts and groups, is valuable for auditing the activity of administrators and Help desk staff.
On DCs, the policy logs changes to domain users, domain groups, and computer accounts. On member servers, the policy logs changes to local users and groups. The primary purpose of the Audit directory service access policy is to provide a low-level audit trail of changes to objects in AD. By using this policy, you can identify exactly which fields of a user account, or any other AD object, were accessed. The policy tracks the same activity as does the Audit account management policy, but at a much lower level.
The information that Audit account management provides is better used for monitoring the maintenance of user accounts and groups. Using the Audit directory service access policy is the only way to track changes to OUs and GPOs—an important task for change-control purposes.
The Audit privilege use policy tracks the exercise of user rights. Microsoft uses the terms privilege, right, and permission inconsistently. This policy generates a lot of noise; we usually recommend that you leave it disabled. The primary purpose of the Audit policy change policy is to notify you of changes to important security policies on the local system.
The policy has six subcategories one of which has the same name as the top-level policy :. The Audit system events policy logs several miscellaneous security events.
The policy has five subcategories:. The preceding audit policies allow you to fire up the Windows auditing function. But when Windows starts sending events to the Security log, you need a way to view them. You must have Manage auditing and security log and Access this computer from the network user rights on the target system. To view another computer's logs, right-click the root in the left pane, and select Connect to another computer.
On the preview pane's General tab, Event Viewer shows more information about each event; select the Details tab to see all of the information. All events in the Security log list the source as Security, with the exception of events That have to do with the logging mechanism itself the source for those tasks is Eventlog.
Security events fall into 50 task categories, which correspond to the 50 audit policy subcategories. Select the Details tab for a different view of the information. Each event ID has a static description that contains defined placeholders; dynamic strings of information that are connected with a particular instance of the event are merged into these placeholders.
Take a look at the information for an instance of event ID Note that the fields offer a combination of static information that appears in every event and dynamic information that is inserted as the event is constructed.
Microsoft attempts to explain some of these event fields, but for a much more detailed and clear explanation, see our wiki. The EventData section appears toward the end of this output. You need to understand how this section works because it is in this section that the important event details reside. String 9 tells you the type of logon that was attempted type 3—a network logon. These dynamic strings are also important when you have a Security log—management solution or want to use a utility, such as Microsoft LogParser, to analyze the log.
Many of the typical alerts that such solutions let you define require criteria that are based in part on one or more strings from an event's description. In most cases, filtering based on event ID alone isn't sufficient.
If you are shopping for a Security log—management product, make sure that it provides the flexibility to create alert criteria and reports that are based on specific string numbers within the description.
The filter in the new Event Viewer is also a big improvement as shown in the screenshot below. In the action pane on the right of Event Viewer, click Filter current event log to access the filter. For the Security log, the only event source available is Microsoft Windows security auditing. You must choose this source in the Event sources drop-down box before you can see and choose which subcategories called task categories in this GUI to filter.
You can use a filtered view to save a subset of event logs for further analysis.
