groups and applications. For more information see www.hp.com/go/upd . The HP Embedded Web
Server also allows you to disable color faxing, color copying, and color print from memory devices.
Protected Protocols – HTTPS
The HP Embedded Web Server features the ability to enable encryption of product communication
through the HTTPS redirection feature. When used, HTTPS prevents others from viewing information
between the EWS and the product via encryption – providing a secure communication method.
Firewall
The HP Embedded Web Server allows the ability to enable and configure product firewall rules,
priorities, templates, services and policies. The firewall feature provides a network-layer of security on
both IPv4 and IPv6 networks. The firewall configuration capability provides control over IP addresses
that are allowed access the product, and the ability to set permissions and priorities for digital send,
management, discovery, and print services--providing a more secure way of controlling access to the
product.
Scan-to and Fax-to Folder Authentication
The Scan-to and Fax-to network folder allows sending to a network folder via the Windows file sharing
mechanism. A username and password may be required to log onto the network where the network
folder is located. In addition, appropriate privileges may be required to have write access to the
network folder.
Syslog
Support of Syslog, a standard protocol for logging status messages to a designated server, can be used
to track the activities and status of devices on the network. The HP Embedded Web Service provides
the ability to enable Syslog and to specify the server to which the status messages will be sent.
Specifying the priority of those status messages is also supported.
