The NSA displays a warning screen if applying your change may disconnect some 
users. Click Apply if you want to continue.

Install System Default CA 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

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.

users to connect through the Internet using FTP over TLS or HTTPs.
