Redefining cyber security with big data analytics

The cyber world is expanding rapidly day by day and more and more people are getting connected to this world, resulting in generation of a large amount of data called Big Data. Along with the cyber world, the number of cyber criminals is also expanding rapidly. To fight against the cyber criminals and safeguard the interest of innocent civilians, we take the help of Big Data Analytics. Big data is large in both quantity and quality and can be efficiently used to analyze certain patterns and behavior anomaly which can help us prevent or be prepared for the thread or any upcoming attack. This proactive and analytical approach will help us greatly reduce the rate of Cyber Crimes and also get the knowledge out of that data which was not previously observable. This paper discusses some of the key characteristics of Big data, architecture, categories of cybercrimes and big data analytic techniques that can be used.
