One message I have read many times is that many people do not trust "the cloud" because of security concerns. Christina Warren has published an article in Mashable.com that answers many of the concerns. She states, "Most major cloud services — including Google and Dropbox — offer a level of security and encryption for data. Still, some data is safer than others."
Christina suggests that the cloud is not for everyone. Actually, she is a bit more specific: it may not be suitable for every application. However, she also points out that the cloud is generally safer and more secure than your own computer is when running on an open Wi-Fi network.

Of course, securing your data stored in the cloud is very easy to do: use encryption. That's what the banks, the stock exchanges, the Federal Reserve System, the military, and even drug dealers do to keep their online data safe from prying eyes. Free encryption software is available for most all operating systems and is easy to use.
