User Account Registration (User Account Enhance Unit)

Most Ricoh devices allow customers to register up to 30 user accounts to

track and limit user access. Installing the optional User Account Enhance

Unit increases capacity to a maximum of 500 accounts to monitor device

usage and restrict larger populations' accessibility to printing functions. Printer

usage data is saved so that it can be exported to an Excel spreadsheet for

reporting/usage analyses.

WPA Support (Wi-Fi Protect Access)

Used in conjunction with the IEEE 802.11a/b/g

Wireless LAN option, WPA is a new security

specification that addresses vulnerabilities in

wireless communications. It provides a high

level of assurance to enterprises, small

businesses, and even home-based users that

data will remain protected by allowing only

authorized users to access their networks.

"Personal" and "Enterprise" authentication and

encryption features block intruders with wirelessly-enabled laptops from tapping into wireless networks

in any environment, preventing the interception of data streams and passwords, or from using the

wireless connection as an entry point into the customer data network.

Kerberos

Kerberos is a network authentication protocol designed to provide strong authentication for client/server

applications by implementing secret-key cryptography. Many internet protocols do not provide any

security for their passwords. Hackers employ programs called "sniffers" to extract passwords to gain

access to networks. Sending an unencrypted password over a network is risky and can open the

network to attack. Kerberos authentication helps to limit the risks caused by unencrypted passwords

and keep networks more secure.

802.1X Wired Authentication

802.1X provides Network-port based authentication for point-to-point communication between network

devices and a LAN port. By providing a point-to-point connection to a LAN port, communication will

terminate if the authentication fails.
