This paper presents a machine-checked high-level security analysis of seL4 — an evolution of the L4 kernel series targeted to secure, embedded devices. We provide an abstract specification of the seL4 access control system in terms of a classical take-grant model together with a formal proof of its decidability. Using the decidability property we show how confined subsystems can be enforced. All proofs and specifications in this paper are machine-checked and developed in the interactive theorem prover Isabelle/HOL
