which three Global settings help ensure the security of a View environment?

Table 1-2. Global Settings for Client Sessions and Connections
Setting Description
Session timeout Determines how long a user can keep a session open after logging in to
View Connection Server.
The value is set in minutes. You must type a value. The default is 600
minutes.
Require SSL for client connections and View
Administrator
Determines if a secure SSL communication channel is used between
View Connection Server and View desktop clients, and between View
Connection Server and clients that access View Administrator.
When you select this setting, clients must use SSL connections.
You must select this setting if you use smart card authentication.
After you change this setting, you must restart the View Connection
Server service to make your change take effect.
Reauthenticate secure VPN connections after
network interruption
Determines if user credentials must be reauthenticated after a network
interruption when you use tunneled, secure VPN connections to the
client.
This setting has no effect when you use direct connection.
After you change this setting, you must restart the View Connection
Server service to make your change take effect.
Message security mode Determines the security of communications between View Manager
components. Specifically, determines if signing and verification of the
JMS messages passed between View Manager components takes place.
For details, see “Message Security Mode for View Components,” on
page 19.
Disable Single Sign-on for Local Mode
operations
Determines if single sign-on is enabled when users log in to their local
desktops.
If you disable this setting, users must manually log in to their desktops
to start their Windows sessions after they log in.
When you change this setting, the change takes effect for each user at
the next user operation.
Enable automatic status updates Determines if View Manager updates the global status pane in the upper
left corner of View Administrator every few minutes. The dashboard
page of View Administrator is also updated every few minutes.
When you enable this setting, idle sessions do not time out for any user
who is logged into View Administrator.
IMPORTANT Disabling idle-session timeouts increases the risk of
unauthorized use of View Administrator. Use caution when you enable this setting.By default, this setting is not enabled. Idle-session timeouts do occur.
