15.4.3 HTTPS
You can set the NWA1000 Series to use HTTP or HTTPS (HTTPS adds security) for Web Configurator sessions.
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).
It relies upon certificates, public keys, and private keys (see Chapter 14 on page 119 for more
information).
HTTPS on the NWA1000 Series is used so that you can securely access the NWA1000 Series using the Web
Configurator. The SSL protocol specifies that the HTTPS server (the NWA1000 Series) must always
authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the
NWA1000 Series), whereas the HTTPS client only should authenticate itself when the HTTPS server requires
it to do so (select Authenticate Client Certificates in the WWW screen). Authenticate Client Certificates is
optional and if selected means the HTTPS client must send the NWA1000 Series a certificate. You must
apply for a certificate for the browser from a CA that is a trusted CA on the NWA1000 Series.
Please refer to the following figure.
1 HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the NWA1000
Series’s web server.
2 HTTP connection requests from a web browser go to port 80 (by default) on the NWA1000 Series’s web
server.
Figure 87 HTTP/HTTPS Implementation
Note: If you disable HTTP in the WWW screen, then the NWA1000 Series blocks all HTTP
connection attempts.
