8.4.1 Introduction to HTTPS

HTTPS is used on the NSA-2400 so that you may securely access the NSA-2400 using the
web configurator. 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.
If you select ONLY Use Secure Connection (HTTPS), then the NSA-2400
will forward HTTP connection attempts to HTTPS. If you clear ONLY Use
Secure Connection (HTTPS), then the NSA-2400 allows both HTTP and
HTTPS connections.
