Sophos Firewall
TMA-SOPHOS-1.1.8
Ensure MFA for Web console access and remote access VPN
Description
MFA adds an extra layer of security to the firewall's web console access. Enforcing MFA significantly reduces the risk of unauthorized configuration changes to the firewall. Similarly, enforcing MFA for the VPN connections adds an additional verification factor beyond passwords, ensuring that only verified users can establish a VPN session Reviewed in the Sophos Firewall web admin console (SFOS has no plain-text configuration export to audit offline).
