Chapter 6. Virtual Private Database

Information security is one of the key challenges that organizations have to address to protect data privacy and its regulation. Leakage of sensitive information or unauthorized access to data might lead to hazardous consequences. With the stringent protocols of data distribution and steep rise of the internet usage, data security can pose a tedious question to the organizations. Information that is prone to invasions can be personal details, financial data, credit card information, business leads, or an intellectual property. A relational database can expose potential areas of injection in the form of network access, over privileged user accounts, non-database file access, non sanitized inputs, and proliferation of production data to unregulated environments. Knowing the fatal consequences of data breaches, the data security solutions must be efficient to bypass the attacks from the database layer, network, and application.
