Table 2-3. Global Security Settings for Client Sessions and Connections
Setting Description
Reauthenticate secure tunnel
connections after network
interruption
Determines if user credentials must be reauthenticated after a network
interruption when Horizon clients use secure tunnel connections to remote
desktops.
When you select this setting, if a secure tunnel connection is interrupted, Horizon
Client requires the user to reauthenticate before reconnecting.
This setting offers increased security. For example, if a laptop is stolen and moved
to a different network, the user cannot automatically gain access to the remote
desktop without entering credentials.
When this setting is not selected, the client reconnects to the remote desktop
without requiring the user to reauthenticate.
This setting has no effect when the secure tunnel is not used.
Message security mode Determines the security mechanism used for sending JMS messages between
components
n When the mode is set to Enabled, signing and verification of the JMS
messages passed between Horizon 7 components takes place.
n When the mode is set to Enhanced, security is provided by mutually
authenticated TLS. JMS connections and access control on JMS topics.
For details, see Message Security Mode for Horizon 7 Components.
For new installations, by default, message security mode is set to Enhanced. If
you upgrade from a previous version, the setting used in the previous version is
retained.
Enhanced Security Status (Read-
only)
Read-only field that appears when Message security mode is changed from
Enabled to Enhanced. Because the change is made in phases, this field shows
the progress through the phases:
n Waiting for Message Bus restart is the first phase. This state is displayed until
you manually restart either all Connection Server instances in the pod or the
VMware Horizon Message Bus Component service on all Connection Server
hosts in the pod.
n Pending Enhanced is the next state. After all Horizon Message Bus
Component services have been restarted, the system begins changing the
message security mode to Enhanced for all desktops and security servers.
n Enhanced is the final state, indicating that all components are now using
Enhanced message security mode.
You can also use the vdmutil command-line utility to monitor progress. See Using
the vdmutil Utility to Configure the JMS Message Security Mode.
Use IPSec for Security Server
connections
Determines whether to use Internet Protocol Security (IPSec) for connections
between security servers and Connection Server instances.
By default, secure connections (using IPSec) for security server connections is
enabled.
