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.
