Microsoft Windows Server

Support Added: FortiSIEM 1.1

Last Modification: FortiSIEM 6.3.3

Vendor: Microsoft

Product Information: https://www.microsoft.com/en-us/windows-server

Supported OS Versions

• Windows 2008 and 2008 R2 (via SNMP, WMI, OMI, Agent)
• Windows 2012 and 2012 R2 (via SNMP, WMI, OMI, Agent)
• Windows 2016 (via SNMP, WMI, OMI, Agent)
• Windows 2019 (via SNMP, WMI, OMI, Agent)
• Windows 2022 (via SNMP, OMI, Agent)
• Windows 10 (OMI, Agent)
• Windows 11 (OMI, Agent)
  
  Note: Starting with FortiSIEM 6.3.3, you can use Open Management Initiative (OMI) to discover and monitor and collect logs from Windows Servers. OMI uses a different API to collect data from the same WMI classes as WMI. So no changes to the Windows Server side is required to accommodate the OMI based communication. In other words, Windows Servers have to be configured identically for both WMI and OMI, and same restrictions apply for both.

Recommendations

1. Use OMI for discovery and performance monitoring.
2. Use Windows Agent for all log collection.

Notes:

1. Installed Software Monitored via SNMP - Although information about installed software is available via both SNMP and WMI/OMI, FortiSIEM uses SNMP to obtain installed software information to avoid an issue in Microsoft's WMI implementation for the Win32_Product WMI class - see Microsoft KB 974524 article for more information. Because of this bug, WMI/OMI calls to the Win32_Product class create many unnecessary Windows event log messages indicating that the Windows Installer has reconfigured all installed applications.
2. Winexe execution and its effect - FortiSIEM uses the winexe command during discovery and monitoring of Windows servers for the following purposes.
   1. Windows domain controller diagnostic (dcdiag) and replication monitoring (repadmin /replsummary)
   2. HyperV Performance Monitoring
   3. Windows Custom performance monitoring – to run a command (e.g. powershell) remotely on windows systems
      

   Note: Running the winexe command remotely will automatically install the winexesvc command on the windows server.

WinRM Configuration

WinRM is needed for WMI/OMI monitoring and also for some FortiSIEM Remediation actions. It is enabled by default.

For WMI/OMI monitoring, WinRM service needs to be running. For FortiSIEM Remediation actions, the following additions steps are needed.

Enable WinRM and Set Authentication

Use the commands below to enable WinRM and set authentication on the target Windows Servers:

1. To configure Windows Server:

   winrm quickconfig

   winrm set winrm/config/service/auth '@{Basic="true"}'

   winrm set winrm/config/service '@{AllowUnencrypted="true"}'

   winrm enumerate winrm/config/listener

   Notes:

   • If HTTPS is not enabled, then open Windows PowerShell console as an administrator, and run the following commands.

   New-SelfSignedCertificate -Subject 'CN=<windows host name>' -TextExtension '2.5.29.37={text}1.3.6.1.5.5.7.3.1'

   winrm create winrm/config/Listener?Address=*+Transport=HTTPS '@{Hostname="<windows host name>"; CertificateThumbprint="<thumbprint received by New-Self Signed Certificate>"}

   winrm quickconfig -transport:https

   winrm enumerate winrm/config/listener

   • Single quotes are needed for Windows 2016 and later.

2. To configure FortiSIEM Client (Super or Collector):

   pip install pywinrm

WMI/OMI Configuration

These configurations are needed if you are using either WMI or OMI to monitor Windows Servers.

• WMI/OMI Configuration for Windows 2012, 2012R2, 2016, 2019, 2022, Windows 10, 11

Kerberos Configuration for OMI

If the Windows Server to be monitored using OMI is part of a Windows Domain that uses Kerberos authentication, then you need to take 2 steps:

1. Add IP to Windows Server name mapping (PTR record) to Windows DNS Server.
2. Add Windows DNS Server name to the list of resolvers in FortiSIEM Collector.

These steps are needed because FortiSIEM uses IP to communicate while OMI/Kerberos needs host name (FQDN).

Windows DNS Server Configuration

1. Log into your Windows DNS server with an admin account.
2. Find Windows Server DNS Manager.
3. Navigate to Forward Lookup under DNS Zones, and locate your DNS domain.
4. Under your DNS domain, locate the host name (A records) for each server you are monitoring via OMI and make sure the IP address is correct.
5. Under Reverse Lookup Zones, look up the zone corresponding to your subnet. Add a PTR record for each server you are monitoring via OMI.

FortiSIEM Collector Configuration

1. Open the file (/etc/resolve.conf)
2. Add Windows DNS Server name to the list of resolvers.
   
   

   [admin@FSM-User]$ cat /etc/resolv.conf
   # Generated by NetworkManager
   ...
   nameserver <Windows DNS Server IP> 
   ...
   

3. Save.

Security Audit Policy Configuration

Because Windows generates a lot of security logs, you should specify the categories of events that you want logged and available for monitoring by FortiSIEM.

1. Log in the machine where you want to configure the policy as an administrator.
2. Go to Programs > Administrative Tools > Local Security Policy.
3. Expand Local Policies and select Audit Policy.
   You will see the current security audit settings.
4. Select a policy and edit the Local Security Settings for the events you want audited. Recommended settings are:

Policy	Description	Settings
Audit account logon events and Audit logon events	For auditing logon activity	Select Success and Failure
Audit object access events	For auditing access to files and folders. There is an additional configuration requirement for specifying which files and folders, users and user actions will be audited. See the next section, File Auditing Policy Configuration.	Select Success and Failure
Audit system events	Includes system up/down messages

File Auditing Policy Configuration

When you enable the policy to audit object access events, you also must specify which files, folders, and user actions will be logged. You should be very specific with these settings, and set their scope to be as narrow as possible to avoid excessive logging. For this reason you should also specify system-level folders for auditing.

1. Log in the machine where you want to set the policy with administrator privileges.
   On a domain computer, a Domain administrator account is needed
2. Open Windows Explorer, select the file you want to set the auditing policy for, right-click on it, and select Properties.
3. In the Security tab, click Advanced.
4. Select the Auditing tab, and then click Add.
   This button is labeled Edit in Windows 2008.
5. In the Select User or Group dialog, click Advanced, and then find and select the users whose access to this file you want to monitor.
6. Click OK when you are done adding users.
7. In the Permissions tab, set the permissions for each user you added.

The configuration is now complete. Windows will generate audit events when the users you specified take the actions specified on the files or folders for which you set the audit policies.

Disabling Audit Token Right Adjusted Success Events

As per Microsoft, it is recommended to Disable "Success" auditing for "Audit Token Right Adjusted".

Reference: https://docs.microsoft.com/en-us/windows/security/threat-protection/auditing/event-4703#security-monitoring-recommendations.

By enabling "Success Auditing" for Audit Token Right Adjusted (Detailed Tracking ), 800+ (4703) events can be generated in a second, resulting in this high volume event impacting system performance.

Complete these steps to disable "Success" for "Audit Token Right Adjusted".

1. Log in, with administrator privileges, to the machine where you want to set the policy.

   On a domain computer, you must have a Domain administrator account.

2. Go to Programs > Administrative Tools > Local Security Policy.
3. Expand to Security Settings > Advanced Audit Policy Configuration > System Audit Policies - Local Group Policy Object > Detailed Tracking.
4. Go to the Detailed Tracking subcategory, and select Audit Token Right Adjusted.
5. Double click Audit Token Right Adjusted, select the Configure the following audit events: checkbox.
6. Uncheck the Success checkbox if needed to disable.
7. Click Apply.
