Security

Ports and Services

The AMX Central Controller features a number of standard services which are on by default. These

services can be individually disabled. The port assignments can be changed for all these services except

FTP. Assigning security profiles will disable some services. A complete list of Ports and Protocols used

across AMX Ethernet enabled products is in Appendix A.

Common Ports and Protocols Used (See Appendix A):

Telnet

Port 23

ICSP

Port 1319

HTTP

Port 80

HTTPS

Port 443

SSH

Port 22

FTP

Port 21

Firewalls

AMX control systems are not required to have internet access to function. There are advanced

applications which may require internet access. For example;

 RMS Enterprise Hosted Cloud Service which will require a HTTP access to the hosted service

 Individual applications on products such as digital signage which require access to external

content sources such as XML or RSS feeds.

 TPControl app for mobile devices

RMS Enterprise Hosted Cloud Service and applications which require external content will always initiate

a data exchange from inside the firewall. External control such as the TPControl app requires an

externally routable IP address on the Central Controller on port 1319. Ports and protocols for all

standard data communications on AMX products are found in Appendix A.

Access Control

AMX Central Controllers allow for multiple user accounts. These accounts should be set up using the

least privilege strategy. This means that privileges are not granted unless necessary and not used unless

intended. The requirement to use role based access control helps to reduce the complexity and

potential errors associated with privileged account maintenance. Accounts may be created individually

on each Central Controller or centrally in an LDAP Server. For more information on access control see

http://www.amx.com/assets/manuals/NetLinxControllers.WebConsole-ProgrammingGuide.FMv4.pdf .

AMX Central Controller security allows the Administrator to define access rights for users or groups. A

user represents a single potential client of the system while a group represents a logical collection of
