Root-Signed Certificates
Root-signed certificates are from a trusted Certificate Authority (CA). Using a certificate signed by a CA
enables you to load one certificate into each browser, allowing access to all printers. Certificates from a
trusted third party are considered more secure than self-signed certificates. Unlike self-signed
certificates, root-signed certificates are not susceptible to man-in-the-middle attacks.

Access Control Lists
Access control lists enable you to limit access to devices, as well as device configuration and
management features. By default, access control lists are unrestricted, which means all computers and
host systems are allowed access.
The printer has four access control lists that may be configured using CentreWare IS:
•
Print Host Access List
: The computers from which users can print. For information on setting up
the Print Host Access List, see
Configuring the Print Host Access List
on page 45.
•
Administrator Access List
: The computers from which you can change printer settings. For
information on setting up the Administrator Access List, see
Configuring Administrator and Key
User Settings
on page 44.
•
Key User Access List
: The computers from which key users can change printer settings. For
information on setting up the Key User Access List, see
Configuring Administrator and Key User
Settings
on page 44.
•
