In this talk, I will give an overview of the various formal verification projects around the evolving seL4 microkernel, and discuss our experience in large-scale proof engineering and maintenance. In particular, the presentation will draw a picture of what these verifications mean and how they fit together into a whole. Among these are a number of firsts: the first code-level functional correctness proof of a general-purpose OS kernel, the first non-interference proof for such a kernel at thedoi:10.1007/978-3-319-06410-9_2 fatcat:fs4qvxrgmzhh5g4qnn2z6fcqpa
