An important aspect of network security for your organization is correctly configuring security for your Microsoft Exchange Server 2007 Unified Messaging (UM) infrastructure. This includes using the security-related configuration options for your Unified Messaging servers and UM-enabled users. By increasing the level of security within your Unified Messaging environment, you increase the level of security for your whole network. This topic contains information and links to security-related topics that can help you increase the level of protection by doing the following:
- Configuring the appropriate PIN settings for users in your
organization
- Enabling the security settings to help protect the Unified
Messaging network data and servers in your organization
- Effectively assigning administrative permissions to manage your
Unified Messaging environment
Unified Messaging Security
There are three security-related areas to consider when you deploy Unified Messaging. You can help increase the level of protection for your network if you correctly plan a Unified Messaging security strategy and then correctly configure the security settings that are available to administrators in the following areas:
- UM-enabled user PIN security When a
subscriber or a UM-enabled user uses a telephone to connect to a
computer that has the Unified Messaging server role installed, they
use Outlook Voice Access to move through the Unified Messaging menu
system. However, before the user can access the Unified Messaging
system, the system prompts them to input their PIN. As the
administrator, you can configure PIN settings and requirements and
perform PIN management tasks. For more information about how to
configure PIN settings for UM-enabled users, see Configuring Security for
Unified Messaging Users.
- Securing Unified Messaging network
traffic There are several security methods
that can help you protect the Unified Messaging servers and the
network traffic in your organization. This includes traffic that is
sent between your IP gateways and Unified Messaging servers and
between your Unified Messaging servers and other Exchange 2007
servers in your organization. For more information about how to
help secure the network traffic that is generated by Unified
Messaging, see Securing Unified
Messaging Network Traffic.
- Configuring permissions for Unified
Messaging In many organizations, there are
separate administrators for Microsoft Exchange, the
Active Directory directory service, and the telecommunications
equipment. Therefore, administrative functions must be delegated to
maintain distinct boundaries between different levels of
administrative permissions. For more information about the security
permissions that are related to Unified Messaging, see Configuring Unified
Messaging Permissions.
