Girding yourself for the security research battle

call to arms to the research community to look toward the future. In this article, I outline a few suggestions for important research directions: software design, usability, and privacy. If we can make any progress on the first two, we could make a strong impact. I highlight the third topic because I think it deserves more attention from the scientific and technical communities, to complement the attention it already receives from the policy and legal communities. Because of my own background in software engineering, I will elaborate more on the first research direction than the other two, but I believe all three deserve equal attention.
