Manageable fine-grained information flow

The continuing frequency and seriousness of security incidents underline the critical 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.
