Securing Big Data: Current Challenges and Emerging Security Techniques

The term big data (BD) refers to the massive amounts of different types of data generated every day. Valuable data and insights can be extracted by utilizing BD to make strategies and take the right decisions, leading to numerous benefits. However, BD presents numerous challenges, including those related to data security and privacy. This paper focuses on BD, its characteristics, and the major security challenges it faces. We then discuss some recent solutions for these security issues, such as blockchain (BC), machine learning (ML), and artificial intelligence (AI) security techniques. We also provide a brief overview of prior research on contemporary security solutions employing ML, AI, and BC. Finally, we provide examples of attacks on BD systems and classic and recent security solutions for them.
