Security

Some of the components of Big Data solutions lack the robustness of traditional enterprise solution environments when it comes to access control and data security. Securing Big Data involves ensuring that the data networks and repositories are sufficiently secured via authentication and authorization mechanisms.

Big Data security further involves establishing data access levels for different categories of users. For example, unlike traditional relational database management systems, NoSQL databases generally do not provide robust built-in security mechanisms. They instead rely on simple HTTP-based APIs where data is exchanged in plaintext, making the data prone to network-based attacks, as shown in Figure 3.2.
