4 Security Tips
In This Chapter
 Enable the Whitelist Feature .................................................................. 30
 Implement Password Protection ............................................................ 30
 Restrict Access to Output Control .......................................................... 30
4.1 Enable the Whitelist Feature
The Whitelist is a security feature built into the sample controller program. It allows you to
authorize up to five phone numbers to have access to the controller via text message
commands.
The Whitelist is disabled by default. When enabled, it filters out text message commands
received from any phone number that is not on the Whitelist. For more information, see
Whitelist.
4.2 Implement Password Protection
If you need a higher level of security, you can add logic to the sample program that checks
any incoming text message command for a password. This feature is not built-in.
4.3 Restrict Access to Output Control
The OUTPUTx ON/OFF command is a powerful feature that allows users to energize or de-
energize digital outputs on the controller via text message commands. If your application
requires higher security, you can delete this feature from the sample program. If you choose
to leave it in, you can use the Whitelist feature to restrict its use to authorized persons only.
