ABSTRACT
As an emerging technique, fog computing is a new computing paradigm that can provide elastic resources at the edge of the Internet to enable many new applications and services. However, fog computing faces unique security and privacy challenges that cannot be well addressed by traditional IT security technologies. Recently, we have seen that big data analytics are changing the surface of security from brand new perspectives in different domains. In this chapter, we briefly introduce fog computing and the state-of-art big data analytics in fog computing. We discuss how big data analytics can come out of cloud and into the fog. We identify several security problems in fog computing, which we can leverage big data analytics to solve. We also analyze the challenges and potential solutions of each problem and highlight some opportunities by surveying existing work in fog computing or in relevant domains.
