An IP access control list (or management VLAN) limits who can reach the EWS, SNMP and raw print ports, reducing exposure to network attacks and to accidental Internet exposure.

In the Embedded Web Server (EWS: browse to https://<printer-ip>/ and sign in as administrator; HP: Security / Networking tabs, Xerox: Properties > Security / Connectivity, Ricoh: Device Management > Configuration, Canon: Settings/Registration > Network Settings / Security Settings) > Networking > Access Control List / IP Filter (Xerox: Connectivity > IP Filtering; Ricoh: Access Control): only the print server(s), management stations and user subnets are allowed, management (EWS/SNMP) limited to the admin subnet; the device is not reachable from the Internet (no NAT/port-forward, verify in external attack-surface scans); direct-to-device printing is limited if a print server is used.

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

EWS: configure the IP access control list / IP filter to allow only print servers and admin subnets for management; place printers in a dedicated VLAN with firewall rules; remove any Internet exposure.
