Securing communications
For local application deployments, where dashboards communicate directly with the Data Server, your options for securing dashboard communications include:
Enabling secure sockets (SSL) in the Data Server
Utilizing a secure channel (SSH) for all dashboard communication
Utilizing a virtual public network (VPN) for all dashboard access
For applet or Web Start deployments, where dashboards communicate through an application server, your options include the following:
Enabling HTTPS in the application server
Utilizing a secure channel (SSH) for all dashboard communication
Utilizing a virtual public network (VPN) for all dashboard access.
As with all encryption technology, there is a cost in performing the encryption and decryption of data. For applications with a very high frequency of data changes, you should account for this cost when you determine how frequently a dashboard can be updated (see the description of the -u or --update option).
