3. Malicious operation, or "hacking"
This is the problem most associated with security concerns - the ability for someone to
access information from a radio system by "listening-in", or to cause damage by transmitting
radio messages to force outputs.
A security option can be selected during the module configuration to protect against this. The
security option (if selected) adds data encryption to radio messages. Modules in the same
system are automatically configured with the encryption key, such that only these modules
can understand each other. "Foreign" modules will hear the messages, but cannot decrypt the
messages. For more information, refer to section 4.2.2.
