LMonad is an Information Flow Control (IFC) framework for Haskell applications. It can be used to enforce security properties like confidentiality and integrity. It is derived from LIO, but is more general in that it tracks information flow for any monad by using monad transformers.
Most code should import the LMonad module.
Trusted code can import the LMonad.TCB module to perform trusted operations.
The LMonadT monad transformer is used to enable IFC for any monad.
Use the LMonad-Yesod library to integrate LMonad into your Yesod application.
