Using the secure Embedded Web Server
The SSL (Secure Sockets Layer) allows for secure connections to the Web server within the print device. You can connect
to the Embedded Web Server more securely by connecting to the SSL port instead of the default HTTP port. The SSL port
connection will encrypt all Web server network communications between the PC and the printer. To connect to the SSL
port:
Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format:
https: //ip_address/.
Supporting SNMPv3 (Simple Network Management Protocol version 3)
SNMPv3 protocol allows for encrypted and authenticated network communications. It also lets the administrator select a
desired level of security. Prior to use, at least one user name and password must be established from the settings page. To
configure for SNMPv3 through the Embedded Web Server of the printer:
1 Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the
format: http://ip_address/.
2 Click Configuration.
3 Under Other Settings, click Network/Ports.
4 Click SNMP.
SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption
Authentication with no encryption
Authentication and encryption
Note: Only the selected level and later may be used to communicate.
Supporting IPSec (Internet Protocol Security)
IP Security protocol provides authentication and encryption of communications at the network layer allowing all application
and network communications over the IP protocol to be secure. IPSec can be set up between the printer and up to five
hosts, using both IPv4 and IPv6. To configure IPSec through the Embedded Web Server:
1 Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the
format: http://ip_address/.
2 Click Configuration.
3 Under Other Settings, click Network/Ports.
4 Click IPSec.
Two types of authentication are supported for IPSec:
Shared Key Authentication—Any ASCII phrase shared among all the participating hosts. This is the easiest way
to configure when only a few hosts on the network use IPSec.
Certificate Authentication—Allows any hosts or subnet of hosts to authenticate for IPSec. Each host must have
a public/private key pair. Validate Peer Certificate is enabled by default, requiring each host to have a signed
