Cyber Security: An Obtainable Goal?

Summary form only given. With the rapid technology advancement and cost reduction, we have built an enormous large Internet. Many critical applications require information to be delivered over Internet. Many small devices like sensors are gradually deployed over Internet. These devices are designed to improve our daily life by monitoring our environment, collecting critical data, and executing special instructions. These devices have gradually become an essential part of our future Internet and most of them are connected to Internet via wireless technology. Unprecedented amount of data are collected by these devices. Security and privacy become great concern for this new world. To meet this challenge, Cyber Trust Program at National Science Foundation has adjusted its research funding directions. We will discuss the current and past research directions in cyber security. What progress has being made? What are missing? Why is it so hard to make cyber space secure? Is it possible that we can accomplish our goal to make cyber space secure?
