Mgmt. Protocols; Web Mgmt - HP Jetdirect J7974E Administrator's Manual

CAUTION
communicate with the HP Jetdirect print server if your system is not properly specified in the list,
or access through HTTP is disabled.
For use of the host access list as a security feature, see
Host systems are specified by their IPv4 addresses or network number. If the network contains subnets,
an address mask may be used to identify whether the IP address designates an individual host system
or a group of host systems.
Examples. See the table of sample entries below:
IP Address
192.0.0.0
192.1.0.0
192.168.1.2
To add an entry into the access control list, use the IP Address and Mask fields to specify a host, and
click (check) the Save checkbox for that entry. Then click Apply.
To delete an entry from the list, clear the Save checkbox for that entry. Then click Apply.
To clear the entire access control list, clear all Save checkboxes, and click Apply.

Mgmt. Protocols

This link provides access to management communications and other protocols that affect security.

Web Mgmt.

Use this tab to manage communications with the embedded Web server from Web browsers. This tab
appears only for full-featured print servers.
Secure, encrypted Web-based communication is provided through the Secure HTTP (HTTPS) protocol.
If configured to require HTTPS, the embedded Web server routes HTTPS communications through port
443, the well-known port for HTTPS traffic. Although ports 80, 280, or 631 continue for Internet Printing
Protocol (IPP) use, other non-secure communications (HTTP) are redirected to HTTPS. Redirection of
your browser to use HTTPS may be transparent depending on your browser's capabilities.
By factory default, HP Jetdirect print servers and printers with IPsec support are configured to require
HTTPS only.
Although not recommended, you may choose to accept both HTTPS and HTTP communications that
are not secure by disabling (clearing) the Encrypt All Web Communication checkbox.
To support the use of HTTPS communications, a Jetdirect certificate must be installed. A factory-default,
self-signed certificate is pre-installed for initial use. Click the Configure button to update the pre-installed
certificate, or to install a new one. For more information, see
The minimum encryption strength that will be allowed must be specified when using a Jetdirect
certificate. You may select Low (default), Medium, or High encryption strength. For example, selecting
