Browser Application Frames
A web page (FIG. 32) can be divided into separate sections or frames, each of which can be independent of
one another and display their own information.
Located on the left side of the populated Browser window is the Navigation frame which allows a user to
navigate throughout the application. Located on the right side of the Browser window is the Active frame
which displays the pages corresponding to the currently selected option from within the Navigation frame.
The first Active frame displayed within the Browser is the Manage WebControl Connections page.
Default Security Configuration
Security for web pages is separated into two access groups: HTTP and Configuration:
HTTP Access allows an authorized user to view these web pages by first requiring the entry of a
username and password at the beginning of every connection session with the target Master. If
Master Security is not enabled, the username and password fields are not displayed and the
Master is openly accessible. The Master Security configuration prevents users from altering any
security or operational parameters. Unless this option is enabled, all subordinate options are
inaccessible and greyed-out.
Configuration access is initially greyed-out until the Master Security option is enabled. This
feature requires an authorized user provide a valid username and password before being granted
access to change configuration and communication parameters on the target Master. Only with this
type of access can a user begin to alter security or operational parameters such as access rights,
Port assignments, System values, and SSL certificate usage.
If a user is not currently logged-into the Master (via the initial Login screen) and they attempt to access a
feature wherein authentication is required, they are prompted with a message to log into the Master (via the
Log In button) (FIG. 33). After the user’s information and rights are confirmed, the login process is
successfully completed and the button changes state and displays Log Out. A user must be logged into the
system before their associated rights can be activated for the current session.
