Security features

 SNMPv3 read-write access and v1/v2c read-only access
In this mode the print server uses the read-write access of version 3 and the read-only access of version 1
and version 2c of the SNMP protocol.
Note
When you use the SNMPv3 read-write access and v1/v2c read-only access mode, some Brother
applications (e.g. BRAdmin Light) that access to the print server do not work properly since they authorize
the read-only access of version 1 and version 2c. If you want to use all applications, use the SNMPv1/v2c
read-write access mode.
 SNMPv1/v2c read-write access
In this mode the print server uses version 1 and version 2c of the SNMP protocol. You can use all Brother
applications under this mode. However, it is not secure since it will not authenticate the user and the data
will not be encrypted.
Note
For more information, see the Help text in Web Based Management.
Printing documents securely using SSL/TLS
7
To print documents securely over the Internet, you can use the IPPS protocol.
Note
• Communication using IPPS cannot prevent unauthorized access to the print server.
• IPPS is available for Windows ® 2000/XP, Windows Vista ® , Windows ® 7 and Windows Server ®
2003/2008.
To use the IPPS protocol, the following machine settings are required.
 A self-signed certificate or a certificate issued by a CA, and a private key must be installed in the machine.
For how to install a certificate and private key, see Using Certificates for device security on page 60.
 The IPPS protocol must be enabled. To enable the IPPS protocol, choose an installed certificate from the
pull-down list in the HTTP Server Settings page of IPP on the Configure Protocol page, and then enable
SSL communication is used (port 443). For information on how to access the Configure Protocol
page, see How to configure the machine settings using Web Based Management (web browser)
on page 40.
