NetLinx Security with a Terminal Connection

NetLinx Masters currently have built-in security capabilities. They require a user entering a valid username and password to access the NetLinx System’s Telnet, HTTP, ICSP, and FTP services.

The security capabilities are configured and applied via a Telnet connection or the NetLinx Master’s RS- 232/USB terminal interface (the RS232/USB Configuration Port).

Always use the RS232/USB Configuration Port when entering potentially sensitive security information. The Telnet server interface exposes this security information to the network in clear text format, which could be intercepted by an unauthorized network client. Using the RS232/USB Configuration Port offers security during the configuration of the database due to the physical proximity of the user to the system.

NetLinx Security Features

NetLinx security allows a qualified user to define access rights for users or groups.

A "User" represents a single potential client of the NetLinx Master, while a "Group" represents a logical collection of users. Any properties possessed by groups (i.e., access rights, directory associations, etc.) are inherited by all the members of the group.

The following table lists the NetLinx features that the administrator (or other 'qualified' user) may grant or deny access to.

NetLinx Security Features

NetLinx Master Security Configuration	The user has access to the security configuration commands of the
	Master. Only those users with security configuration access rights
	granted will have access to the security configuration
	commands.
Telnet Security	The user has access to the Telnet server functionality. All basic
	commands are available to the user.
Terminal (RS232/USB) Security	The user has access to the Terminal server functionality through the
	USB connector. All basic commands are available to the user.
HTTP (web server) Security	The user has access to the HTTP server functionality. Directory
	associations assign specific directories/files to a particular user.
FTP Security	The user has access to the FTP server functionality. Only the
	administrator account has access to the root directory; all other
	'qualified' clients are restricted to the /user/ directory and its 'tree'.
ICSP	The user has access to the ICSP communication functionality.
	Communication and encryption rights are available to an authorized
	user.
ICSP Encryption	The user has access to the ICSP data encryption functionality.
	Enabling encryption of ICSP data requires that both:
	- AMX hardware or software communicating with the target
	Master provide a valid username and password.
	- All communication is encrypted.
