Opis

It is recommended to limit exposure of Firewall administration services from WAN/untrusted zone. When necessary, leverage on remote VPN or limiting only from selected IP addresses, or use of Sophos Central for firewall administration. 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. Reviewed in the Sophos Firewall web admin console (SFOS has no plain-text configuration export to audit offline).
