I must be missing something here....

Saw an article about a new experimental security technology

Technique offers enhanced security for sensitive data in cloud computing

the final line of the article, which is very light on details, is:

In testing, the SICE framework generally took up approximately 3% of the system's performance overhead on multi-core processors for workloads that do not require direct network access. "That is a fairly modest price to pay for the enhanced security," Ning says. "However, more research is needed to further speed up the workloads that require interactions with the network."

Don't get me wrong, I'm all for new and innovative ways to protect our data in the cloud.... but.... this one has low overhead for data IN THE CLOUD when it is not communicating with THE NETWORK.... right, so data that is accessible ONLY over a network or the Internet is protected at low overhead costs when it IS NOT ACCESSED.... yeah.... I'm must be missing something here.
