NetLinx Security and Web Server
NetLinx Masters (installed with firmware build 130 or higher) incorporate new built-in security
and SSL certificate verification capabilities. By using both SSL certificate verification and secured
HTTP access, this new NetLinx firmware provides users with a more convenient web-based
method of securing both the Master and the incoming and outgoing information.
Terminal setup and security configuration is still valid and supported in the new build of NetLinx
Master firmware. New Terminal security features include the use of two new commands:
ssl
security enable and ssl security disable.
SSL (Secure Sockets Layer) is a protocol that works by encrypting data that is transferred over the
SSL connection. URLs that require an SSL connection begin with https: instead of http: in the
browser’s Address field. These security capabilities are configured to function via a web session
within your browser.
The new NetLinx Web Server used to power the security and SSL certificate features on AMX
Masters not only provides user name/password security for the target Master, but also a new level of
secure encryption through the use of a unique server certificate.
The first layer of security for the Master is an on-screen HTTP user name and password field that
prompts a user to provide correct security information before gaining access to a target Master. The
second layer of protection is an SSL Certificate (specifically identifying the target Master) that can
either be requested or self-generated. This certificate is then installed onto the target Master and
added to the trusted site certificate listing within the computer’s Internet browser.
NetLinx Security web browser and feature support
The following table describes the web browsers (associated to each operating system)
recommended for use with the new NetLinx Security features on the NI Controllers.
After the installation of build 130 or higher to your Master, Telnet security configuration access is
disabled. This new build migrates the NetLinx Master security setup from a TELNET environment
to a web-based application.

the target Master and will display an invalid certificate message.
