DESCRIPTION
Select the Force HTTPs option to turn on the NSA's web
browser security. Anyone who connects via HTTPS to the NSA
must install the public key certificate associated with it.
Note: The NSA will restart the web configurator after you
click Apply.
The NSA displays a warning screen if applying your change may
disconnect some users. Click Apply if you want to continue.
Click Download button to save a copy of the NSA's public key
certificate to your local computer. This is useful for installing the
certificate without having to connect to the NSA, or for sending
by email to other users for them to install prior to logging into
the NSA for the first time. After saving the certificate to your
computer, double-click it to install it.
Note: Each web browser handles certificate installation
differently. See Appendix D on page 285
information.
Select Edit a self-signed CA certificate, then follow the on-
screen instructions for creating a public key certificate signed by
the NSA as the local certificate authority.
Note: Use certificates created and signed by the NSA if the
device is not open to external access.
Select Create a certificate authorized by other CA, then
follow the on-screen instructions to install a certificate that has
been authorized by a third-party certificate authority.
Note: Use this method if the device is open to external
access, such as allowing users to connect through the
Internet using FTP over TLS or HTTPs.
