Tight Enforcement of Information-Release Policies for Dynamic Languages

Paper i proceeding, 2009

This paper studies the problem of securing information release in dynamic languages. We propose (i) an intuitive framework for information-release policies expressing both what can be released by an application and where in the code this release may take place and (ii) tight and modular enforcement by hybrid mechanisms that combine monitoring with on-the-fly static analysis for a language with dynamic code evaluation and communication primitives. The policy framework and enforcement mechanisms support both termination-sensitive and insensitive security policies.
