Local configuration

The ossec.conf file is the main configuration file on the Wazuh manager, and it also plays a role on the agents. It is located at /var/ossec/etc/ossec.conf both in the manager and agent. It is recommended you back up this file before making changes to it, as an error in the configuration can completely prevent Wazuh services from starting up.

The ossec.conf file is in XML format, and all configuration options are nested in their appropriate section of the file. In this file, the outermost XML tag is <ossec_config>. For example, here is an example of the proper location of the alerts configuration section:

<ossec_config>
    <alerts>
        <!--
        alerts options here
        -->
    </alerts>
</ossec_config>

The agent.conf file is very similar to ossec.conf except that it is used to centrally distribute configuration information to agents. See more here.

Wazuh can be installed in two possible ways: the Wazuh manager uses the “server/manager” installation type and agents use the “agent” installation type.
