Abstract

In typical Web applications, the access control at the database management system is not effective due to the dependency on application behavior. That is, once the information is retrieved, a careless application can easily leak the information to undesirable parties. In addition, database accounts are often shared for multiple Web users in order to allow connection pooling. We propose DIFCA-J (Dynamic Information Flow Control Architecture for Java), to keep track of and control fine-grained information propagation through execution of the program. DIFCA-J allows controlling the information flow at run-time, without needing to modify the source code of the target application or the Java VMs.
