wazuh-authd
The wazuh-authd program can automatically add a Wazuh agent to a Wazuh manager and provide the key to the agent. It's used along with the agent-auth application. The program creates an agent with an IP address of any instead of using a specific IP address.
Warning
By default, there is no authentication or authorization involved in this transaction, so it is recommended that this daemon only be run when a new agent is being added.
wazuh-authd is able to generate X.509 certificates used for manager verification. OpenSSL is not required.
The certificate parameters are specified in the CLI:
# wazuh-authd -C 265 -B 2048 -K /var/ossec/etc/sslmanager.key -X /var/ossec/etc/sslmanager.cert -S "/C=US/ST=California/CN=wazuh/"
If any of the parameters related to the certificate generation is missing, an error is triggered and the certificates are not generated.
