Audit Configuration

You can easily change the default settings for the following audit reports:

  • Windows Defender
  • Windows Firewall
  • Object Access
  • File Change Tracking
  • Best Practice Analyzer
  • User Authentication

In this section, we will discuss the configuration for these audit reports.

Windows Defender

In order to enable Windows Defender reports, make sure that Collector ID: 137 is enabled.

If the Windows Defender collector is enabled, VirtualMetric also tracks Windows Event Logs for Windows Defender activities. VirtualMetric collects the following events:

Make sure that these Event Log definitions are also enabled. You can always customize these settings to filter Windows Defender events.

Windows Firewall

In order to enable Windows Firewall reports, make sure that Collector ID: 54 is enabled.

Windows Firewall Log Collector (ID: 54)

If the Windows Firewall Log collector is enabled, VirtualMetric uses the Windows Firewall Log file or Security Audit events to collect Windows Firewall activities. VirtualMetric collects the following events:

Windows Firewall Settings

With the default settings, VirtualMetric collects firewall logs via the Windows Firewall log file.

mode=file

If you want to enable file logging on Windows Firewall, go to Windows Firewall, right click on Windows Firewall, and click Properties.

Click Customize for the logging properties.

Choose Yes for logging dropped packets. You can also enable logging of successful connections if they are needed.

After making these changes, VirtualMetric will start reading the Windows Firewall log file via the Inventory Collector. You can also switch the collector mode to Event for real time collection. Go to the collector definition settings and change the mode to Event:

mode=event

To activate event logging for Windows Firewall, you must make some changes on the Local Group Policy settings. Open Local Group Policy and go to Windows Settings -> Security Settings -> Local Policies -> Audit Policy.

Make sure that bot Success and Failure events are selected.

VirtualMetric collects the following events of Windows Firewall:

Filtering Platform Connection - Permitted (ID: 88)

Make sure that these Event Log definitions are also enabled. You can always customize these settings to filter Windows Firewall events.

Object Access

In order to enable Object Access Auditing reports, make sure that Collector ID: 144 is enabled.

Windows Object Access Audit Collector (ID: 144)

To activate event logging for Object Access Auditing, you must make some changes on the Local Group Policy settings. Open Local Group Policy and go to Windows Settings -> Security Settings -> Local Policies -> Audit Policy.

Make sure that both Success and Failure events are selected.

For test purposes, go to Properties of the sensitive file.

Switch to the Security tab and click the Advanced button.

Switch to the Auditing tab and click the Add button.

Click on Select a principal, type Everyone, and click the OK button.

Select All for type, and switch to Advanced Mode. Select the events for logging, and click the OK button.

Click Apply and then the OK button to save the changes.

VirtualMetric collects the following events of Object Access Auditing:

Object Access Auditing (ID: 95)

WRITE_DAC The right to modify the discretionary access control list (DACL) in the object's security descriptor.
WRITE_OWNER The right to change the owner in the object's security descriptor.
SYNCHRONIZE ✖︎ The right to use the object for synchronization. This enables a thread to wait until the object is in the signaled state. Some object types do not support this access right.
ACCESS_SYS_SEC ✖︎ The ACCESS_SYS_SEC access right controls the ability to get or set the SACL in an object's security descriptor.

With the default settings, VirtualMetric uses the following audit types in the collector settings:

{% code overflow="wrap" lineNumbers="true" %}

accessmode=ReadData,ListDirectory,WriteData,WRITE_DAC,WRITE_OWNER,AddFile,AppendData,AddSubdirectory,Execute,Traverse,DeleteChild,DELETE

{% endcode %}

If you want to enable other access types, you can modify the collector settings. After modifying the accessmode options, click the Submit button to apply the changes.

File Change Tracking

In order to enable Windows File Change Tracking reports, make sure that Collector ID: 139 is enabled.

Windows File Change Tracking Collector (ID: 139)

By default, VirtualMetric uses the following white list and the black list to filter file changes:

extensionWhiteList=.ps1,.vbs,.exe&extensionBlackList=.log,.evtx

If you clear these settings, VirtualMetric logs all file changes. You can use extensionBlackList to filter some file extensions like .log or .evtx etc. You can also add some file type extensions to always log via the extensionWhiteList setting. If you want to set these lists, you can modify the collector settings.

After modifying the options, click the Submit button to apply the changes.
