Manageable fine-grained information flow
The continuing frequency and seriousness of security incidents underlines the importance of application security. Decentralized information flow control (DIFC), a promising tool for improving application security, gives application developers fine-grained control over security policy and privilege management. DIFC developers can partition much application functionality into untrusted components bound by a kernel- or language-enforced security policy. Unless a (usually smaller and less exposed) trusted component is exploited, the effects of an application compromise are contained by the policy. Although system-based DIFC can simultaneously achieve high performance and effective isolation, it offers a challenging programming model. Fine-grained policy specifications are spread over several application pieces. Common programming errors may be indistinguishable from policy exploit attempts; the system cannot expose developers to information about these errors, complicating debugging. S...
