Internet of Things-“Big Data Security” Big data related IoT applications are a great benefit to organizations and many other large and small scale industries. Today, the main focus is on security issues in IOT that are associated with big data. Diversifying the concentration of attackers, Hackers on big data and reduce the adverse impact on big data, requires new technological methods in addition to security techniques. The main challenges include capture of data, curation, storage of data, transfer and sharing of data requires a strong security and privacy. The proposed recommendations to overcome security problems are unsolved. I would like to Research and address those security problems and do more research on how they can improve cyber security more effectively. Some of the Proposed Recommendations are Human Computer Interaction, Robust Key and Data Authenticity. Can IoT be secured? Colomo-Palacios [2018],Big data must be protected to prevent malicious data breaches. The growing cyber-security threats imply that organizations should expect and prepare for data breach, and design and implement measures to detect such breaches in a timely manner to minimize their negative impacts and make data secure and data management systems resilient. Organizations are expected to comply with data security regulations and report to both the regulator and individual consumers affected when a data breach takes place. As data volume and computing infrastructures get large, traditional methods of data security mechanisms for securing small-scale data and infrastructure are becoming inadequate [[29]]. Roger et al. [[30]] identified three levels of analytics capability of firms (from low to high), including aspirational, experienced, and transformed.
