Language-based security analysis of database applications

In today´s information-age, databases are at the heart of information systems. Unauthorized leakage of confidential database information, while computed by the associated database applications, may put the system at risk. Language-based information flow analysis is a promising field of research to detect possible information leakage in any software systems. So far, researchers pay little attention to the case of applications embedding database languages. In this paper, we address the need of proper analysis of data manipulation languages, and we overview the possible extension of language-based approaches to the case of information systems supporting databases at the back-end.
