13.4.3 HTTPS
You can set the NWA/WAC 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 12 on page 121 for more
information).
HTTPS on the NWA/WAC is used so that you can securely access the NWA/WAC using the Web
Configurator. The SSL protocol specifies that the HTTPS server (the NWA/WAC) must always authenticate
itself to the HTTPS client (the computer which requests the HTTPS connection with the NWA/WAC),
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 NWA/WAC a certificate. You must apply for a certificate
for the browser from a CA that is a trusted CA on the NWA/WAC.
Please refer to the following figure.
1 HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the NWA/
WAC’s web server.
2 HTTP connection requests from a web browser go to port 80 (by default) on the NWA/WAC’s web server.
Figure 86 HTTP/HTTPS Implementation
Note: If you disable HTTP in the WWW screen, then the NWA/WAC blocks all HTTP connection
attempts.
