This paper presents SecureBlox, a declarative system that unifies a distributed query processor with a security policy framework. SecureBlox decouples security concerns from system specification, allowing easy reconfiguration of a system's security properties to suit a given execution environment. The implementation of SecureBlox is a series of extensions to LogicBlox, an emerging commercial Datalog-based platform for enterprise software systems. SecureBlox enhances LogicBlox to enable distribution and static meta-programmability, and makes novel use of existing LogicBlox features such as integrity constraints.
