Before you begin
If you started with SGBox from version 5.3.0 or above and/or if you have never installed the old SGBox Windows packages Windows package Base and Windows package Advanced, you don’t need to cleanup anything; just follow the standard installation steps.
However, if you’re an old SGBox customer, or if you’ve installed one or both of the old packages, a little cleanup procedure needs to be followed to avoid duplicate events. Please follow the instruction at the end of the “Windows Audit package installation” section.
Windows Audit package installation
To install the new Windows Audit package From SCM->Application->Packages find the package in the package list, click the Install button and then the Download and install button on the App Installation pop-up.
On the Windows Audit – Recommended installation panel, configure installation option as for your needs:
- Select the hosts from which you want to collect Windows Audit information from. These hosts will be automatically added to the Windows Audit Classes, so events collection can immediately start after the installation.
- Download the Group Policy configuration guide and follow the instruction to properly enable needed events collection.
- Insert the email address to which you want to forward LCE alert messages to.
- Check the flag if you want to have newly added/installed windows machines automatically added to SGBox Windows Audit classes.
- Click Install button to install the package.
To check the installation, please verify the existence of the following:

Post installation considerations
We need also to make sure that the new Windows Agent Configuration are correctly bound to the relative windows hosts. Go to LM->Configuration->Agents and check that everything is fine.
Open the Microsoft Windows (SGBox agent) Asset (1) and verify that all the needed “configurations” (2) are properly assigned to to your Windows devices. Don’t forget to click the Save Changes button, in the bottom-left corner, if you did any change.
To eventually force the system to push configurations to the Agents, simply remove and newly add a Configuration from a device of your choice, and finally click the Save Changes button.
Please note that for events collection to be effective, it is necessary to appropriately configure both the Group Policies and the Object-level Access auditing. Here below the link to the configuration guide:

Old Windows package cleanup instruction
If you have installed one or both of the old SGBox Windows packages Windows package Base and Windows package Advanced, you need to configure the following to avoid duplicate events generation:
Deactivate old packages’s classes
From LM->Configuration->Class uncheck the Active flag for the following classes:
- Windows logon events
- Windows user events
- Windows File Access
- Windows Audit Policy
- Windows GPO
After verifying that everything works as expected with the new Windows Audit package, you may want to remove old objects to keep the environment clean.
Clean old Classes
From LM->Configuration->Class delete the previously deactivated classes:
- Windows logon events
- Windows user events
- Windows File Access
- Windows Audit Policy
- Windows GPO
Clean old Dashboards
From the Dashboard list delete the following dashboards:
- Top 10 windows user logon events
- Windows User Operations
- Windows user related issue
Clean old Correlation Rules
From LCE->Rules delete the following rules:
- Windows User Added to Group
- Windows User Password Changed
- Windows User Password Reset
- Windows User Removed from group
- Windows Audit Policy Changed
Clean old Agent Configuration
From LM->Configuration->Agents remove the following configurations:
- Windows logon events
- Windows user events
- Windows Audit Policy
- Windows GPO
Clean old Windows packages
Identify and remove old Windows packages by clicking on the trash in the upper-right corner of each package box
Please note that deleting the package will not remove package objects, so the previous point by point cleanup is necessary.
