For additional security control - RBAC and administrative accounts can be enabled with 2-factor authentication using built-in RADIUS Server. By disabling ‘HTTPS', ‘SSH' and ‘Network services (PING/PING6, DNS, SMTP RELAY, SNMP)' on WAN zone to protect against reconnaissance attempts, network scanners and potential adversary.
