7.4 Security
Use this screen to change the admin password and elect to allow only HTTPS web connections
to the NSA.
7.4.1 Introduction to HTTPS
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web
protocol that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-
level protocol that enables secure transactions of data by ensuring confidentiality (an
unauthorized party cannot read the transferred data), authentication (one party can identify the
other party) and data integrity (you know if data has been changed).
HTTPS relies upon certificates, public keys, and private keys.
HTTPS is used on the NSA so that you may securely access the NSA using the web
configurator. The SSL protocol specifies that the SSL server (the NSA) must always
authenticate itself to the SSL client (the computer which requests the HTTPS connection with
the NSA), whereas the SSL client only should authenticate itself when the SSL server requires
it to do so. You must apply for a certificate for the browser from a CA that is a trusted CA on
the NSA.
Note: If you select Only Use Secure Connection (HTTPS), then the NSA allows
HTTPS connections only. HTTP connection attempts are forwarded to HTTPS.
If you clear Only Use Secure Connection (HTTPS), then the NSA allows both
HTTP and HTTPS connections.
