Setting security using the Embedded Web Server (EWS)
You can enhance the security of network communications and device configuration by using the advanced security options.
These features are available through the Web page of the device.
Setting the system password
Setting the system password protects configuration of the Embedded Web Server. A system password is also required for
Secure mode and confidential communication with MVP.
To set the system password:
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 Security.
4 Click Create Password, if one has not been set previously. If a password has already been set, click Change or
Remove Password.
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.
