TMA-PRINTER-MGMT-ACCESS-CONTROL

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.
修正方法
修正方法: ガイダンスまたは IaC パッチ
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.
