Cybersecurity and privacy are two hot topics in our society. However, both of them are mainly uncharted territories, and we have far more questions than answers from applications all the way to theories. In this talk, we review the state-of-art of the fields based on two research topics: distributed denial of service and big data privacy, respectively, aiming to present audience an overview of the current battle ground. We also discuss the problems and challenges that we are facing, and explore the possible promising directions in the fields.
