TMA-SOPHOS-5.8
Ensure Firewall Rules with SMB, Netbios, RDP and other unencrypted protocols should not be directly accessible from WAN Zone
説明
Window service ports directly accessible from WAN zone could lead to bruteforce attempts, wormable attacks and other unpatched vulnerabilities. Unencrypted protocols that could potentially impact confidentiality, integrity and availability shouldn't be directly accessible from the WAN Zone. Reviewed in the Sophos Firewall web admin console (SFOS has no plain-text configuration export to audit offline).
