Microsoft Active Directory Adding and Authorization by WMI

Introduction

This article will provide information about the process of sending system logs of your Active Directory server to Logsign Unified SecOps Platform.

You can integrate your log server with syslog or wmi protocols, and in this document, the process will be carried out with the wmi protocol.

Recommendations for Audit Settings

You can review Advance Audit to check the audit settings.

The recommendations are for enterprise computers that have average security requirements and high functionality. Organizations with higher security requirements should consider and apply more aggressive audit policies.

Windows PowerShell Auditing

Windows PowerShell keeps a detailed log of both command scripts and interactive access. If large PowerShell command scripts are frequently used, they can cause excessive event logging and noise. We recommend configuring this before deploying it organization-wide in a test environment.

 

Group Policy Recommended Value
Computer Configuration\Policies\Administrative Templates\Windows Components\Windows PowerShell
Turn on Module Logging  Active/ *
Turn on PowerShell Script Block Logging  Active

 

Windows CMD Terminal Controls

Group Policy Recommended Value
Computer Configuration\Policies\Administrative Templates\System\Audit Process Creation
Include command line in process creation events Active

 

Authorization Operations for Domain Controller (ADS Server)

To connect to the log source with the wmi protocol and obtain logs with a wmi query, we need to create a user.

 

Creating a User:

To create a user, we go to Active Directory Users and Computers.

To prevent the created user's password from expiring and to avoid log interruptions, we check the Password never expires checkbox. With this option, you can apply your organization's security policies.

 

Group Memberships:

To enable the Logsign user to access the channels under eventviewer, they must be a member of certain groups, which are:

  • Distributed Com Users,
  • Performance Log Monitor,
  • Performance Log Users
  • Event Log Reader

Membership of the above groups should be provided to the Logsign user.

WMIMGMT Configuration:

To allow the Logsign user to connect to the source with wmi, the following permissions must be defined through wmimgmt.msc.

DCOMCNFG Configuration:

To allow the Logsign user to connect to the source with wmi, the following permissions must be defined through dcomcnfg.

Automation Script (Performing Operations with Script)

You can use a script to perform all authorizations for Windows Domain Controller source, other servers connected to the domain, and workgroup sources.

 

Performing Operations with Script on Domain Controller Server:

The script is executed with admin privileges. The username, password, and domain information to be created are entered, and the process is completed.

There are two scripts in the folder. The script starting with user create will create a new user, while the other script can perform operations with an existing user.

The script file is attached.
