Big Data: Related Technologies, Security Challenges, and Research Opportunities

Big Data is generally defined in association with the “Four V’s”: high volume, high velocity, high variety and high veracity. Millions of organizations worldwide are embarking into Big Data projects recently, in order to better support their R&D activities, decision making process, creating marketing strategies and customer relationship management. However, Big Data comes with challenges. This paper reviews the security challenges of Big Data and investigates whether existing data protection mechanisms can be further adapted to protect Big Data processing. This paper also looks into related technologies such as Hadoop, Cloud Computing and Internet of Things (IoTs), as well explore research opportunities in securing Big Data processing.
