The new front door
Security agencies around the world have repeatedly warned that attackers are focusing on edge devices: firewalls, VPN gateways, routers and remote-access appliances. These devices sit directly on the internet, often run with high privileges and are rarely monitored as closely as servers and laptops.
Why they are attractive
A single vulnerable edge device can give an attacker direct access into the internal network, bypassing email filters and endpoint protection. Many organisations also leave management interfaces exposed to the internet or keep default settings in place.
Best practice for edge security
Keep an up-to-date inventory of every internet-facing device. Subscribe to vendor security advisories and apply critical patches within days, not months. Never expose management interfaces to the internet; use a dedicated management network or VPN. Replace devices that no longer receive security updates. Log and review authentication attempts and configuration changes.
Secure by default
Good vendors reduce risk before the device is even installed: unique default passwords for every unit, management access disabled from the WAN by default, signed firmware and a clear security update policy. These principles guide the development of Navijin gateways and access points.
