Big Data: Big Promises for Information Security

Big Data is related to technologies for collecting, processing, analyzing and extracting useful knowledge from very large volumes of structured and unstructured data generated by different sources at high speed. Big Data creates critical information security and privacy problems, at the same time Big Data analytics promises significant opportunities for prevention and detection of advanced cyber-attacks using correlated internal and external security data. We must address several challenges to realize true potential of Big Data for information security. The paper analyzes Big Data applications for information security problems, and defines research directions on Big Data analytics for security intelligence.
