Administrative 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 certificate and the authority certificate must be installed. Each host must have its identifier in the Subject Alternate Name of the signed certificate. Note: After a device is configured for IPSec with a host, IPSec is required for any IP communication to take place. Using Secure mode You can configure the TCP and UDP ports to one of three modes: • Disabled-Never allows network connections to this port. • Secure and Unsecure-Allows the port to remain open, even in Secure mode. • Unsecured Only-Allows the port to only open when the printer is not in Secure mode. Note: A password must be set to enable Secure mode. Once enabled, only the ports set to Secure and Unsecure will be open. To configure the Secure mode for TCP and UDP ports from 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 TCP/IP Port Access. Note: Disabling ports will disable function on the printer. Setting security using the Embedded Web Server (EWS) 82

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
certificate and the authority certificate must be installed. Each host must have its identifier in the
Subject Alternate
Name
of the signed certificate.
Note:
After a device is configured for IPSec with a host, IPSec is required for any IP communication to take
place.
Using Secure mode
You can configure the TCP and UDP ports to one of three modes:
•
Disabled
—Never allows network connections to this port.
•
Secure and Unsecure
—Allows the port to remain open, even in Secure mode.
•
Unsecured Only
—Allows the port to only open when the printer is not in Secure mode.
Note:
A password must be set to enable Secure mode. Once enabled, only the ports set to Secure and
Unsecure will be open.
To configure the Secure mode for TCP and UDP ports from 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
TCP/IP Port Access
.
Note:
Disabling ports will disable function on the printer.
