Making Software Sandboxing Practical using Language-based Techniques
Software sandboxing or software-based fault isolation (SFI) is a lightweight approach to building secure systems out of untrusted components. The idea of SFI is old. Its use in production, to sandbox third-party libraries in Firefox, is new. We describe the PL techniques—notably static information flow control—that were key to deploying SFI in practice and their use in tackling software security more generally.
