NetLinx Security within the Web Server

NI-3101-SIG Signature Series NetLinx Integrated Controller
Setting the system security options for a NetLinx Master
This page simply toggles the requirement of a user to enter a valid username and password before gaining
access to a particular feature. For every action, the Master validates whether a username and password are
required and whether the user has sufficient rights. Refer to theSecurity - Group Level Security page section on
page 44 for more information on the assignment of the Group/User rights. For example, if the user were
attempting to modify the configuration parameters of the Master, their username and password must be
associated with a profile which was previously granted Configuration Access privileges within the web server.
If they their profile didn’t have enough rights to accomplish their action an "Insufficient Rights..." message
appears on top of the active page.
1. Enter the URL/IP Address of the target Master into the Address/URL field within the web browser.
Initially the connection is unsecured and communication can be made via an HTTP connection. Refer to
theAccessing an Unsecured Master via an HTTP Address section on page 34 for more detailed
instructions.
2. Click the Security Level link (from within the Security section of the Navigation frame) to open the
System Security page. The Master Security checkbox selection (FIG. 38) toggles the appearance of the
NetLinx Master security options.
3. Click on the Master Security checkbox to access to the security parameters on the target Master and
allow an authorized user (with configuration access rights such as an Administrator) the ability to alter
the subordinate security parameters. Refer to theSecurity - System Level Security page section on page 39
for more detailed field descriptions.
4. Click on the desired access parameters and configuration checkboxes necessary to require user validation
prior to usage.
Enabling the Terminal, HTTP, and Telnet Access options require that a valid username and
password be entered prior to gaining access to the desired action. If the HTTP Access option is
enabled, upon the initial connection to the Master (via the web browser) the Login page
appears and requires a valid username and password be entered before allowing access to the
web server pages.
Enabling the Configuration option requires that the user be logged in and their rights validated
before allowing any modification to the current Master security configuration and communication

Each selection simply toggles the security setting from enabled to disabled.
By default, the Master Security option is disabled (unchecked), including the
subordinate Master Security components (even though they might show a
checkmark, they are greyed out). An open Master does not require a user to enter a
valid username and password.
