3.3 Security Certificate

The NFN-GW-EM-3 communicates with the browser using secure communications. When connecting to the
NFN-GW-EM-3, the browser may display a security warning. An example is shown in
NFN-GW-EM-3 includes a self-signed security certificate which causes the browser to display the warning.
The self-signed security allows the encrypted connection between the NFN-GW-EM-3 and the browser.

The browser warning is displayed upon each connection to the NFN-GW-EM-3. The warning may be
removed by obtaining a security certificate from a security authority. The certificate may originate from a
local certificate authority or a commercial certificate authority if the NFN-GW-EM-3 is directly connected
to the Internet with a unique IP address. Regardless of which type of certificate authority is selected, the IP
address of gateway must be provided. The certificate is specific to the specified IP address. If the IP address
is changed, a new certificate will be required. In addition, the certificates have an expiration date. For
example, June 1, 2015. Once the certificate expires, a new certificate needs to be sent to the
NFN-GW-EM-3. If the certificate expires, a different warning is displayed by the browser.
The security certificate must be in the PFX format. The PFX file is uploaded to the NFN-GW-EM-3 using
the Tools menu in the NFN-GW-EM-3 configuration. The option "Send PFX Key File" completes the
operation. It may also be necessary to install a file on the PCs which are used to configure the
NFN-GW-EM-3 to fully resolve the security configuration.
The site network administrator may be able to assist with any additional details regarding security
certificates.
