Secure and Insecure Service Access From the WAN
12.4.1 Service Access Limitations
A service cannot be used to access the NWA/WAC when you have disabled that service in the
corresponding screen.
12.4.2 System Timeout
There is a lease timeout for administrators. The NWA/WAC automatically logs you out if the
management session remains idle for longer than this timeout period. The management session
does not time out when a statistics screen is polling.
Each user is also forced to log in the NWA/WAC for authentication again when the reauthentication
time expires.
You can change the timeout settings in the
User
screens.
12.4.3 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
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
