From Fine- to Coarse-Grained Dynamic Information Flow Control and Back, a Tutorial on Dynamic Information Flow. (arXiv:2208.13560v1 [cs.PL])

This tutorial provides a complete and homogeneous account of the latest
advances in fine- and coarse-grained dynamic information-flow control (IFC)
security. Since the 70s, the programming language and the operating system
communities have proposed different IFC approaches. IFC operating systems track
information flows in a coarse-grained fashion, at the granularity of a process.
In contrast, traditional language-based approaches to IFC are fine-grained:
they track information flows at the granularity of program variables. For
decades, researchers believed coarse-grained IFC to be …
