Windows Event Forwarding (WEF) is a service available on Microsoft Windowsplatforms which enables the forwarding of events from Windows Event Log toa central Windows Event Collector. Since the technology is built into theoperating system, this means you can centralize log collectionwithout having to install third party software on each Windowsnode. You can also use Group Policy for configuring clients to forward theirevents. This approach not only standardizes client management but alsostreamlines it.

Unfortunately there is one caveat. Events are sent over the WS-Eventing protocol(part of theWS-Managementprotocol) and this typically limits the Windows Event Collector to a Windowsserver, which may not be practical in environments where Windows servers arenot common. NXLog Enterprise Edition addresses this problem through itsWindows Event Collector (im_wseventing)module, allowing a Windows Event Collector to be set up on GNU/Linuxsystems.

In this post, we will show you how to set up a WEC server onLinux using either Kerberos or certificate-based authentication. Theseinstructions have been verified on RHEL/CentOS 8 and Ubuntu 20.04 for the WECserver, and on Microsoft Windows Server 2016 for Active Directory and WEFclients. Note that the steps may differ on other versions and operating systems.

Going forward, we will refer to the Linux host where NXLog Enterprise Edition isinstalled as the WEC server and the Windows machine forwarding events to it asthe WEF client.

Configure a WEC server with Kerberos authentication

These steps will guide you through setting up Kerberos authentication,configuring a WEC server, and forwarding events to it from a WEF client. Thisexample setup uses three distinct hosts:

A Windows Active Directory Domain Controller with FQDN dc.example.com andIP address 192.168.0.1.
A Windows based DNS server with IP address 192.168.0.2.
A Linux host where NXLog Enterprise Edition is installed with hostname linux-wecand IP address 192.168.0.3.

WEC server prerequisites

Before configuring Kerberos authentication, the Linux host acting as aWEC server needs to satisfy the following requirements.

Check that the machine has the correct hostname:
```
# hostname
```
If the command does not return a value or the value is incorrect, updatethe hostname:
```
# hostnamectl set-hostname linux-wec
```
Configure network settings with the correct DNS server and a static IPaddress.
To set network settings on RHEL/CentOS (replace ifcfg-enp0s3with the correct interface name):
```
# nano /etc/sysconfig/network-scripts/ifcfg-enp0s3
```
Set to:
```
BOOTPROTO=staticIPADDR=192.168.0.3NETMASK=255.255.255.0GATEWAY=192.168.0.1DNS1=192.168.0.2
```
To set network settings on Ubuntu 18.04 and newer:
1. Open the Netplan YAML configuration file (replace the filename with therelevant one on your system):
  # nano /etc/netplan/01-network-manager-all.yaml
2. Set to (replace enp0s3 with the correct interface name):
  network: version: 2 renderer: NetworkManager ethernets: enp0s3: dhcp4: no addresses: - 192.168.0.3/24 gateway4: 192.168.0.1 nameservers: addresses: [192.168.0.2]
  Note that using correct indentation is very important or the settings will notbe applied.
3. Apply the changes:
  # netplan apply
Synchronize the time with the domain controller.
To synchronize the time using NTP execute the following command:
```
# ntpdate dc.example.com
```
To synchronize the time using chrony:
1. Open the chrony configuration file with a text editor:
  # nano /etc/chrony.conf
  (Video) How to Set up Windows Event Log Forwarding [Step-by-Step]
2. Replace the current server or pool with the following line:
  server dc.example.com iburst

Create and map an Active Directory domain user

For a WEC server on a Linux machine to be able to use Kerberos authentication,a corresponding user needs to be created in Active Directory and mappedto a Kerberos principal name.

On the domain controller, create a new user with its logonname matching the hostname of the WEC server.
1. Go to Administrative Tools > Active Directory Users and Computers >example.com > Users.
2. Right click and choose New > User.
  1. First name: linux-wec
  2. Full name: linux-wec
    See Also
    Scoped logging using Microsoft Logger with Serilog in .Net Core Application - Init Pals Windows エージェントのリリース
  3. User logon name: linux-wec
  4. Set a password for the user.
  5. Uncheck User must change password at next logon.
  6. Check Password never expires.
3. Right click on the new user, click Properties, and open the Account tab.
  1. Check This account supports Kerberos AES 128 bit encryption.
  2. Check This account supports Kerberos AES 256 bit encryption.
On the DNS server, create an A record for linux-wec.example.com.
1. Go to Administrative Tools > DNS > Forward Lookup Zones >example.com.
2. Right click and choose New Host (A or AAAA)….
3. Add a record with name linux-wec and IP address 192.168.0.3.
4. Check the Create associated pointer (PTR) record option.

Back on the domain controller, open a command prompt and execute thesecommands. Use the same <password> that was specified when the above user wascreated. These commands map the domain account to the Kerberos principalnames and generate two keytab files containing the shared secret.

> ktpass /princ hosts/linux-wec.example.com@EXAMPLE.COM /pass <password> /mapuser EXAMPLE\linux-wec -pType KRB5_NT_PRINCIPAL /out hosts-nxlog.keytab /crypto AES256-SHA1

> ktpass /princ http/linux-wec.example.com@EXAMPLE.COM /pass <password> /mapuser EXAMPLE\linux-wec -pType KRB5_NT_PRINCIPAL /out http-nxlog.keytab /crypto AES256-SHA1

Copy the resulting hosts-nxlog.keytab and http-nxlog.keytab files tothe WEC server.

Configure Kerberos on the WEC server

Now that the Active Directory user has been created and mapped to the principalname, the WEC server can be configured for Kerberos authentication.

Confirm that the Kerberos krb5 client and utility software are installed onthe WEC server. The required package can be installed withyum install krb5-workstation or apt install krb5-user.
Edit the default Kerberos configuration file, usually located at/etc/krb5.conf.
1. In section [domain_realm] add:
  .example.com = EXAMPLE.COMexample.com = EXAMPLE.COM
2. In section [realms] add:
  EXAMPLE.COM = { kdc = example.com admin_server = example.com}

Use ktutil to merge the two keytab files generated above.

# ktutilktutil: rkt /root/hosts-nxlog.keytabktutil: rkt /root/http-nxlog.keytabktutil: wkt /root/nxlog-result.keytabktutil: q

Validate the merged keytab.

# klist -e -k -t /root/nxlog-result.keytabKeytab name: FILE:/root/nxlog-result.keytabKVNO Timestamp Principal---- ------------------- ------------------------------------------------------ 5 17.01.2021 04:20:08 hosts/linux-wec.example.com@EXAMPLE.COM (aes256-cts-hmac-sha1-96) 4 17.01.2021 04:20:08 http/linux-wec.example.com@EXAMPLE.COM (aes256-cts-hmac-sha1-96)

(Video) Setting up event forwarding.

Either copy the keytab into place, or merge it if there are already keys in/etc/krb5.keytab.

To copy the keytab:

# cp /root/nxlog-result.keytab /etc/krb5.keytab

To merge the keytab and validate the result:

# ktutilktutil: rkt /etc/krb5.keytabktutil: rkt /root/nxlog-result.keytabktutil: wkt /etc/krb5.keytabktutil: q

# klist -e -k -t /etc/krb5.keytabKeytab name: FILE:/etc/krb5.keytabKVNO Timestamp Principal---- ------------------- ------------------------------------------------------ <other entries> 5 17.01.2021 04:20:08 hosts/linux-wec.example.com@EXAMPLE.COM (aes256-cts-hmac-sha1-96) 4 17.01.2021 04:20:08 http/linux-wec.example.com@EXAMPLE.COM (aes256-cts-hmac-sha1-96)

Verify that the user account used by the NXLog service has sufficientprivileges to open and read the /etc/krb5.keytab file. If not, Kerberosauthentication will fail.
Test that the authentication with Active Directory is working successfullywhen using the keytab. Run the following command on the Linux WEC server.If the configuration is correct a ticket-granting ticket (TGT) will becreated and cached. This command should be invoked with the same user thatthe NXLog service runs as. By default, it uses the nxlog useraccount.
```
# kinit -kt /etc/krb5.keytab http/linux-wec.example.com@EXAMPLE.COM
```

Verify the ticket was obtained by running klist as the same user from theprevious step:

# klistTicket cache: KCM:0Default principal: http/linux-wec.example.com@EXAMPLE.COMValid starting Expires Service principal28/01/21 11:41:44 28/01/21 21:41:44 krbtgt/EXAMPLE.COM@EXAMPLE.COM renew until 04/02/21 11:41:44

Configure NXLog to receive events

Once you verify that Kerberos authentication is working successfully, the nextstep is to configure NXLog with theWindows Event Collector (im_wseventing)module to receive events from WEF clients.

Open the NXLog configuration file with a text editor. On Linux thedefault location is /opt/nxlog/etc/nxlog.conf.
Add an input module instance of im_wseventing as follows. This configurationuses all network interfaces to listen for connections on port 80, andfilters for events from the Application, Security, and System channels.
nxlog.conf
```
<Input windows_events> Module im_wseventing Address http://linux-wec.example.com:80/wsman ListenAddr 0.0.0.0 Port 80 <QueryXML> <QueryList> <Query Id="0"> <Select Path="Application">*</Select> <Select Path="Security">*</Select> <Select Path="System">*</Select> </Query> </QueryList> </QueryXML> # Log connections for testing and troubleshooting LogConnections TRUE</Input>
```
Note
Make sure the port defined in the im_wseventing configuration isaccessible from the WEF clients. The local firewall rules on the LinuxWEC server may need to be updated.
Restart the NXLog service:
```
# systemctl restart nxlog
```

Configure the WEF client to send events to NXLog

Finally, WEF clients can be configured to forward their events to the newlyset up WEC server. Follow these steps to enable WEF on a singleWindows node by editing the local policy.

Open the Group Policy MMC snap-in (gpedit.msc) and go toComputer Configuration > Administrative Templates >Windows Components > Event Forwarding.
Right-click the Configure target Subscription Manager setting and selectProperties. Enable the setting, and under Options click theShow button to add a server address.
Add at least one setting that specifies the NXLogWEC server. The SubscriptionManager Properties windowcontains a Help pane that describes the syntax for thesetting. An example would be as follows:
```
Server=http://linux-wec.example.com:80,Refresh=30
```
Note
The Refresh interval represents the time in seconds and on productionsystems should be set to a higher value e.g. Refresh=1200.
After the SubscriptionManager setting has been added, ensure the policy isapplied by running:
```
> gpupdate /force
```
If you are planning to forward security events, you will need to grant theNetworkService account access to the Security log. SeeForwarding events from the Security login the NXLog Enterprise Edition Reference Manual for instructions.
At this point the WinRM service on the Windows client should connect toNXLog. If the LogConnections directive is set to TRUE in theNXLog configuration, a connection attempt should be logged innxlog.log and you should start seeing events as they arrive.

Configure a WEC server with certificate-based authentication (HTTPS)

These steps will guide you through generating the required certificates usingOpenSSL, setting up a WEC server with HTTPS, and forwarding events to it froma WEF client. This example setup uses two distinct hosts:

A Linux host where NXLog Enterprise Edition is installed with hostname linux-wec.
A Windows host which will be configured as a WEF client with hostnamewinclient.

Generate the certificates

To facilitate the generation of certificates using OpenSSL, scripts areavailable in ourpublic git repository.

Download the scripts to the Linux WEC server. You may want to edit the subjectparameters according to your environment.
Generate the CA certificate and private key.
```
# ./genca.sh
```
Generate the WEF client certificate and export it together with the CA in PFXformat. This is the certificate that you will need to import into the Windowscertificate store on the WEF client later on.
```
# ./gencert-client.sh winclient.example.com
```
Generate the WEC server certificate to be used by the NXLogconfiguration. Make sure that the hostname you specify matches the reverseDNS name of the WEC server, otherwise you may encounter errors whenconfiguring the WEF client because the SSL certificatecontains a common name (CN) that does not match the hostname.
```
# ./gencert-server.sh linux-wec.example.com
```

If you are using an intermediary CA you will need to make sure that theca-cert.pem file contains the public part of every issuer’s certificate in thecorrect order. The easiest way to achieve this is to 'cat' the pemcertificates together.

If you do not use the provided scripts to generate the certificates, make surethat the following requirements are met:

The WEF client certificate must have theX509 v3 Extended Key Usage: TLS Web Client Authentication extension.
The WEC server certificate must have theX509 v3 Extended Key Usage: TLS Web Server Authentication extension.
Make sure that the intended purpose of the certificates are set to ClientAuthentication and Server Authentication respectively.

Configure NXLog to receive events

Once the certificates have been generated, the next step is to configureNXLog with theWindows Event Collector (im_wseventing)module to receive events from WEF clients.

Open the NXLog configuration file with a text editor. On Linux thedefault location is /opt/nxlog/etc/nxlog.conf.

Add an input module instance of im_wseventing as follows. This configurationuses all network interfaces to listen for connections on port 5985, andfilters for events from the Application, Security, and System channels.

nxlog.conf

<Input windows_events> Module im_wseventing Address https://linux-wec.example.com:5985/wsman ListenAddr 0.0.0.0 Port 5985 HTTPSCertFile /path/to/server-cert.pem HTTPSCertKeyFile /path/to/server-key.pem HTTPSCAFile /path/to/ca-cert.pem <QueryXML> <QueryList> <Query Id="0"> <Select Path="Application">*</Select> <Select Path="Security">*</Select> <Select Path="System">*</Select> </Query> </QueryList> </QueryXML> # Log connections for testing and troubleshooting LogConnections TRUE</Input>

Note	Make sure the port defined in the im_wseventing configuration isaccessible from the WEF clients. The local firewall rules on the LinuxWEC server may need to be updated.

Restart the NXLog service:
```
# systemctl restart nxlog
```

Configure the WEF client to send events to NXLog

At this stage, you are ready to configure WEF clients to forward their eventsto the newly set up WEC server. Follow these steps to configure the WinRMauthentication method and enable WEF on a Windows node.

Make sure the Windows Remote Management (WS-Management) service isinstalled, running, and set to Automatic startup type.
If WinRM is not already installed, see the MSDN documentation onInstallation and Configuration for Windows Remote Management.
Check that certificate-based authentication is enabled for WinRM. Run thefollowing command:
```
> winrm get winrm/config/Client/Auth
```
This should produce the following output:
```
 Auth Basic = false Digest = true Kerberos = true Negotiate = true Certificate = true CredSSP = true [Source="GPO"]
```
If Certificate authentication is set to false, enable it with the followingcommand:
```
> winrm set winrm/config/client/auth @{Certificate="true"}
```
Import the WEF client authentication certificate. Open the Certificates MMCsnap-in for the Local Computer (certlm.msc), right click on Personal andselect All Tasks > Import…. Import the client.pfx file. Enter theprivate key password if set and make sure theInclude all extended properties check-box is selected.
Note
After the import is complete, expand Personal > Certificates and double-click on the WEF client certificate to check if the full certificate chain is available and trusted.
(Video) Windows Event Forwarding at Scale
The NetworkService account needs to be granted permission to accessthe WEF client certificate. Use theWindows HTTP Services Certificate Configuration Tool (WinHttpCertCfg.exe)to check if the NetworkService account has the correct access permission:
```
> winhttpcertcfg -l -c LOCAL_MACHINE\my -s <certificate subject name>
```
Where LOCAL_MACHINE\my refers to the Personal certificate store of theLocal Computer and <certificate subject name> is the CN value that wasspecified when creating the WEF client certificate. For example:
```
> winhttpcertcfg -l -c LOCAL_MACHINE\my -s winclient.example.com
```
If NetworkService is not listed in the output, grant it permission byrunning the following command:
```
> winhttpcertcfg -g -c LOCAL_MACHINE\my -s <certificate subject name> -a NetworkService
```
If you are planning to forward security events, you will need to grant theNetworkService account access to the Security log. SeeForwarding events from the Security login the NXLog Enterprise Edition Reference Manual for instructions.
Configure the policy on the WEF client to enable event forwarding:
1. Open the Group Policy MMC snap-in (gpedit.msc) and go toComputer Configuration > Administrative Templates >Windows Components > Event Forwarding.
2. Right-click the Configure target Subscription Manager setting and selectProperties. Enable the setting, and under Options click theShow button to add a server address.
3. Add at least one setting that specifies the NXLogWEC server. The SubscriptionManager Properties windowcontains a Help pane that describes the syntax for thesetting. If you have used the gencert-server.sh script the subscriptionmanager string should be in the following format:
  Server=HTTPS://<FQDN of im_wseventing>:<port>/wsman/,Refresh=<refresh interval in seconds>, IssuerCA=<certificate authority certificate thumbprint>
  Note
  On production systems the Refresh interval should be set to a highervalue e.g. Refresh=1200.
4. To find the IssuerCA fingerprint, open the Certificates MMC snap-in, expandLocal Computer > Personal > Certificates and open the CA certificate.Copy the Thumbprint from the Details tab. Please make sure to eliminatespaces and the invisible non-breaking space that may be present beforethe first character of the thumbprint on Windows 2008.
5. After the SubscriptionManager setting has been added, ensure thepolicy is applied by running:
  > gpupdate /force
At this point the WinRM service on the Windows client should connect toNXLog. If the LogConnections directive is set to TRUE in theNXLog configuration, a connection attempt should be logged innxlog.log and you should start seeing events as they arrive.

Troubleshooting

The steps in this post aim to provide a working example to set up WindowsEvent Forwarding in practice. However, due to the multitude of componentsrequiring configuration and no two environments being exactly the same, any oneof these factors could result in WEF not working as expected. The best way totroubleshoot WEF is to check for errors in Windows Event Log. The followingchannels provide the most relevant events:

Applications and Services Logs/Microsoft/Windows/Event-ForwardingPlugin
Applications and Services Logs/Microsoft/Windows/Windows Remote Management

For additional resources, theWindows Event Collector (im_wseventing)documentation in the NXLog Enterprise Edition Reference Manual provides aTroubleshootingsection with tips and solutions for common issues.

Summary

In this post we have seen how using WEF with NXLog Enterprise Edition creates newpossibilities for the centralized log collection of events from Windowsclients in organizations where Windows servers are rare or non-existent.By using theWindows Event Collector (im_wseventing)module, a WEC server can be set up on GNU/Linux to receive events forwarded toit by Microsoft Windows clients.

With both NXLog Enterprise Edition and WEF supporting either Kerberos orcertificate-based authentication, we hope this post provides you with theinformation needed for getting started with configuring a WEC server in yourenvironment, according to your organization’s preferred authentication method.
