        The required ports and protocols for communications between Guardian, CMC, and Vantage.
    - Install an SSL certificate
      You need to install a secure sockets layer (SSL) certificate to securely encrypt traffic between client computers and the Nozomi Networks Operating System (N2OS) sensor over hypertext transfer protocol secure (HTTPS).
    - Install a CA certificate
      If an issuing certificate authority (CA) for the hypertext transfer protocol secure (HTTPS) certificate is not immediately trusted, you will need to install a certificate authority (CA) certificate to the Nozomi Networks Operating System (N2OS) sensor.
    - Enable SNMP
      To monitor the health of the Nozomi Networks Operating System (N2OS) sensor, you need to enable the simple network management protocol (SNMP) daemon.
    - Configure an internal firewall
      Do this procedure to configure the internal firewall to restrict access to components such as: the management interface, the secure shell (SSH) terminal, the simple network management protocol (SNMP) service, and internet control message protocol (ICMP) of the full stack edition.
    - Disable internal packet-rate protection of the management interface
      If necessary, do this procedure to disable internal packet-rate protection in the management interface.
    - Configure IPv6
      You can configure IPv6 to access physical and virtual sensors. This is not possible for container installations.
    - Enable 802.1x on the management interface
      This topic describes how to enable 802.1x support for the management interface. Configuration of the RADIUS server and the creation of possible certificates are not discussed
    - USB port disablement
      The Nozomi Networks Operating System (N2OS) does not support universal service bus (USB) ports.
