Big Data has developed into a essential for business, researchers, healthcare, and government agencies. Big  Data  deals  with  collection  of  enormous digital  information  for  analysing,  visualizing  and  to  draw  the insights for the prediction & prevention of cyber-attacks. The  world  is  becoming  more  and  more interconnected  with  the  advent of the Internet of Things  and  new  technologies. The  users  are producing  more  and  more  Internet of Things (IOT)  data  from  different devices  and  systems  in  the  unstructured  form  which  is highly unmanageable and this management of data is the challenging job. In this paper we elaborate various security issues related to big data and their possible solutions to overcome the problems. After all what are the security and challenges facing Big Data?
