Table 23. 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 View components takes place.
n
When the mode is set to Enhanced, security is provided by mutually authenticated
SSL JMS connections and access control on JMS topics.
For details, see Message Security Mode for View 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 View Message Bus Component service on all Connection Server hosts in the
pod.
n
Pending Enhanced is the next state. After all View 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 View Connection Server instances.
By default, secure connections (using IPSec) for security server connections is enabled.
