only true way to secure communications is to encrypt the data. This can happen
at different parts of the system, such as ecrypting the data before it is send.
It can also occur in creating the connection between the two systems. Typically
this is using a secure session protocol, such as HTTPS or SSL. It can then even
occur at the lowest layers, such as the encryption that occurs with the WEP key
in wireless networks. One of the most importnat factors is to know that the data
is secure against malious attacks, this a good understanding of the methods used
is important.
