Using Certificates for device security
1
Your Brother machine supports the use of multiple security certificates allowing secure management,
authentication and communication with the machine. The following security certificate features can be used
with the machine. When you print a document or use Web Based Management (web browser) securely using
SSL, you must install the certificate onto your computer. See Digital Certificate Installation uu page 4.
SSL/TLS communication
SSL communication for SMTP/POP3
The Brother machine supports the following certificates.
Pre-installed certificate
Your machine has a pre-installed self-signed certificate.
Using this certificate, you can easily use the SSL/TLS communication without creating or installing a
certificate. If you want to use your machine's Google Cloud Print feature, you can use this pre-installed
certificate to configure the Google Cloud Print settings securely. For more information on Google Cloud
Print, go to the Brother Solutions Center at click Manuals on your model
page to download the Google Cloud Print Guide.
Note
The pre-installed self-signed certificate cannot protect your communication from spoofing. We recommend
using a certificate that is issued by a trusted organization for better security.
Self-signed certificate
This print server issues its own certificate. Using this certificate, you can easily use the SSL/TLS
communication without having a certificate from a CA. (See Creating a self-signed certificate uu page 6.)
Certificate from a CA
There are two methods for installing a certificate from a CA. If you already have a certificate from a CA or
if you want to use a certificate from an external trusted CA:
• When using a CSR (Certificate Signing Request) from this print server. (See Creating a Certificate
Signing Request (CSR) uu page 7.)
• When importing a certificate and a private key. (See Import and export the certificate and private key
