Why should big data be more difficult to secure? According to the survey conducted by Business Intelligence and Information Management, shows that analysis of big data is top priority. Among those 47% of marketers were very or extremely interested and 9% had no interest in big data analysis.
What are driving these initiatives?
- 44% marketers say its predicting customers behavior

- 27% expect to predict fraud or financial risk
But the Big Data landscape is incredibly diverse across the following three areas;
- Data Forms – It can be structured, like databases and transactional data, or it could be unstructured office documents, images, raw data stored as flat files.
- Data Sources – It includes financial accounting applications, sales and product data, CRM applications, email files sever logs, office files, images, mobile device data including geolocation and much more.
- Data Consumers – They range from department-level to analysts to senior business managers to IT and business users.

Big Data can be protected through a smart mix of technology and policy. Introduction of this may be tipping point for adoption of modern security practices.
- Log everything, it’s the only way you can reliably detect unauthorized activities
- Use a system to make sense of log data, as you cannot do it manually.
- Analyze and audit for sensitive information in motion.
- Understand the security of any application that has access to sensitive information
- Invest in identity and access management – it’s the only way to apply the principle of least privilege.
