The following steps serve as a guide on how to configure a Windows endpoint agent for automatic enrollment via the agent configuration method:
The Wazuh agent installation directory depends on the architecture of the host:
C:\Program Files (x86)\ossec-agentfor 64-bit systems.
C:\Program Files\ossec-agentfor 32-bit systems.
Using an administrator account, modify the Wazuh agent configuration file
ossec.confin the installation directory. For this guide, we are assuming a 64-bit architecture. Hence,
C:\Program Files (x86)\ossec-agent\ossec.conf
Include the Wazuh manager IP address or DNS name in the
<client> <server> <address>MANAGER_IP</address> ... </server> </client>
This will allow the agent to connect to the Wazuh manager and automatically request a key.
(Optional) Add enrollment parameters in the
<client> ... <enrollment> <agent_name>EXAMPLE_NAME</agent_name> <groups>GROUP1,GROUP2,GROUP3</groups> ... </enrollment> </client>
These agent enrollment parameters are optional, and they provide the agent with specific information that should be used during enrollment. Some common enrollment parameters are below:
<agent_name>EXAMPLE_NAME</agent_name>: This specifies the name the endpoint should be enrolled as. When this is not specified, it defaults to the endpoint hostname.
<groups>GROUP1,GROUP2,GROUP3</groups>: This specifies the group(s) in which the agent should be added. An agent group is a collection of agents that would share the same configuration. This allows the manager to push configuration settings to a set of agents that belong to the same group. The agent enrollment will fail if a non-existent group is specified. Therefore, it is necessary to create the desired group on the manager before using the group parameter. Additional information on agent groups can be found here.
More optional enrollment parameters and their usage are provided here.
Restart the agent to make the changes effective.
# Restart-Service -Name wazuh
# net stop wazuh # net start wazuh
Select the “agents” tab to check for the newly enrolled agent and its connection status in the Wazuh dashboard to confirm that enrollment was successful.
