13.4.1 Service Access Limitations

A service cannot be used to access the NWA1123 when you have disabled that service in the

corresponding screen.

There is a lease timeout for administrators. The NWA1123 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 NWA1123 for authentication again when the reauthentication time

expires.

You can change the timeout settings in the User screens.

You can set the NWA1123 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

information).

HTTPS on the NWA1123 is used so that you can securely access the NWA1123 using the Web

Configurator. The SSL protocol specifies that the HTTPS server (the NWA1123) must always authenticate

itself to the HTTPS client (the computer which requests the HTTPS connection with the NWA1123),

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 NWA1123 a certificate. You must apply for a certificate

for the browser from a CA that is a trusted CA on the NWA1123.
