(See Import and export a CA certificate on page 70.) Note • If you are going to use SSL/TLS communication, we recommend that you contact your system administrator first. • When you reset the print server back to its default factory settings, the certificate and the private key that are installed will be deleted. If you want to keep the same certificate and the private key after resetting the print server, export them before resetting and re-install them.

Using Certificates for device security
7
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.
SSL/TLS communication
IEEE 802.1x authentication
SSL communication for SMTP/POP3
The Brother machine supports the following certificates.
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 and installing a certificate
on page 62.)
Certificate from a CA
There are two methods for installing a certificate from a CA. If you already have 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
How to create a CSR
on page 67.)
•
When importing a certificate and a private key. (See
Import and export the certificate and private key
on page 68.)
CA certificate
If you use a CA certificate that identifies the CA (Certificate Authority) itself and owns its private key, you
must import a CA certificate from the CA, prior to the configuration. (See
Import and export a CA certificate
on page 70.)
Note
•
If you are going to use SSL/TLS communication, we recommend that you contact your system
administrator first.
•
When you reset the print server back to its default factory settings, the certificate and the private key that
are installed will be deleted. If you want to keep the same certificate and the private key after resetting the
print server, export them before resetting and re-install them. (See
How to export the self-signed
certificate, the certificate issued by a CA, and the private key
on page 69.)
