Nuance Management Center Server Installation and Configuration Guide
About Nuance Management Center
Nuance Management Center allows Dragon administrators to manage all Dragon clients from a single central
console. The Nuance Management Center (NMC) console allows you to do the following:
l Configure options for clients at the site and group level
l Centrally manage your Dragon product licensing
l Share data, like words and auto-text commands, with Dragon clients and across other Nuance
products
l Audit user session events
l Monitor client usage and trends through reporting
You can choose to install, configure, and maintain your own Nuance Management Center (NMC) server onpremise, or you can use the Nuance cloud-hosted NMC server.
2
Physical architecture
Nuance Management Center is a standard Microsoft ASP .NET MVC web application that is hosted by
Internet Information Services (IIS). The Nuance Management Center components include the following:
l Nuance Management Center (NMC) server—Stores application data, such as organizations,
sites, groups, and users. It also stores transient data, such as log files.
l Nuance Management Center (NMC) console—Allows NMC administrators to create and manage
objects, like groups and users, assign licenses, run reports, and more. The NMC console does not
have permanent data storage. However, it does use a file share for temporary data storage to support
file uploads and downloads.
l Database instance—Stores license information, partial speech profiles, application usage
information, and audit data.
l Dragon clients—Users log in to their client computers where Dragon is installed and connect to
your NMC server to access shared words and commands.
Initially, you install the NMC server, NMC console, and the database instance on the same server. However,
you can optionally move your database instance to a separate database server after the installation. Your
NMC server can be one of the following:
Chapter 1: Introduction
l A single physical machine (smaller installations)
l Multiple physical machines load-balanced by a network traffic switch (larger installations)

Nuance Management Center Server Installation and Configuration Guide
Security considerations
When your organization implements Nuance Management Center, it is critical to install the software and its
system components using secure installation methods to protect the integrity and confidentiality of your data.
It is equally important to manage and monitor your system once installed to ensure that your data is protected
from unauthorized access and misuse.
The following sections provide secure installation and configuration guidelines, and describe the security
features provided in Nuance Management Center to help you manage and monitor your system.
General security principles
l
Require strong, complex user account passwords.
Create a password policy to establish password requirements. For example, require a minimum
password length and one aspect of complexity, such as non-alphabetical characters.
l
Keep passwords secure.
When you initially create user accounts in Nuance Management Center, send users their username
and initial password in separate email messages. Instruct your users not to share or write down
passwords, or store passwords in files on their computers. In addition, require users to change their
default passwords upon first use, and on a regular basis.
For more information, see the Users must change their password after first login Organization
option and the Maximum password age - password will expire in n days Organization option in
the NMC Help.
l
Keep software up-to-date.
Keep all software versions current by installing the latest patches for all components, such as SQL
Server and Microsoft® Windows Server, including all critical security updates.
l
Implement the principle of Least Privilege.
In implementing the principle of Least Privilege, you grant users the least amount of permissions
needed to perform their jobs. You should also review user permissions regularly to determine their
relevance to users’ current job responsibilities.
l
Monitor system activity.
Review user audit records regularly to determine which user activities constitute normal use, and
which may indicate unauthorized use or misuse.
l
Promote policy awareness.
Ensure your employees are aware of Acceptable Use policies, best practices, and standard
operating procedures that are relevant to Nuance Management Center.
Installing and configuring Nuance Management Center securely
The Nuance Management Center installation instructions include procedures that install the application and
system components into a secure state by default. In addition to performing the standard installation
procedures, you can do the following to secure Nuance Management Center.
l
Establish best practices for downloading report data.
15
Nuance Management Center provides the option to save report data to a CSV file. Establish best
practices for downloading data to ensure the data remains secure outside of Nuance Management
Center.
Nuance Management Center security features
Nuance Management Center provides the following security features to help you secure your system.
Authentication
You can choose from three different authentication methods. You can also select from flexible password
options to establish a user account password policy.
Authentication methods
Nuance Management Center requires users to authenticate by logging in with a unique username and
password. You can use the following authentication methods.
l Single sign-on via Nuance Central Authentication—Cloud deployments can enable single sign-
on to allow users to log in to Nuance Management Center using their Windows credentials. This is
most secure method for cloud deployments as users do not have to manage a separate set of
credentials for Nuance Management Center and administrators do not have to manage a password
policy.
Chapter 2: Preparing for your installation
l
Single sign-on via Active Directory—On premise deployments can enable single sign-on to allow
users to log in to Nuance Management Center using their Windows credentials. This is most secure
method for on premise deployments as users do not have to manage a separate set of credentials for
Nuance Management Center and administrators do not have to manage a password policy.
l
Native Nuance Management Center authentication—Users log in to Nuance Management
Center using a login and password that you create when you create user accounts in the NMC
console.
Pas sword settings
Nuance Management Center provides password options that you can select to establish a user account
password policy for your user accounts. Using the options, you can require specific password content,
complexity, and expiration.
For more information, see the "Organization Details page" topic in the NMC Help.
Auditing
The Nuance Management Center auditing feature is a standard feature that cannot be disabled. Auditing
tracks specific system events that occur in the NMC console, capturing information about those events to
allow you to better monitor the actions that occur. The NMC console allows administrators to audit specific
events, such as user or administrator logins, over a specific period of time.
By default, Nuance Management Center retains event data for one year.
For more information, see the "Viewing audit events" topic in the NMC help.
User Access Control
Nuance Management Center allows you to implement user access control using roles and permissions to
restrict user access to only what is necessary for users to perform their job responsibilities. Before
implementing user access control, establish an access control policy based on business and security
requirements for each user. Review your access control policy periodically to determine if changes to roles
and permissions are necessary.
16
Nuance Management Center Server Installation and Configuration Guide
Assigning privileges
Privileges determine the ribbons, menus, and options that users can access in the NMC console. You assign
or unassign privileges to show or hide those options. You should assign the least amount of privileges that
users require to perform all tasks relevant to their job responsibilities.
For more information on privileges and assigning them, see the Configuring group security section in the
"Managing groups" topic in the NMC help and the "Privileges reference" appendix in the Nuance Management
Center Administrator's Guide.
Assigning grants
Grants determine the objects that users can access in the Nuance Management Center database, such as
sites, groups, and users. Generally, you assign different grants to providers than you would to administrators.
You should also assign the least amount of grants that users require to perform their job responsibilities.
For more information on grants and assigning them, see the Configuring group security section in the
"Managing groups" topic in the NMC help.
Disabling inactive use rs
Nuance Management Center allows you to disable inactive user accounts after a number of days of inactivity.
Disabled users can no longer authenticate to Nuance Management Center. By disabling inactive user
accounts, you can prevent unauthorized system access by employees who have left your organization.
For more information, see the Disable inactive users after n days Organization option in the "Organization
Details page" topic in the NMC help.
