seL4: What its formally verified microkernel guarantees

Cited to explain what formal verification of seL4 guarantees, such as ruling out whole classes of bugs like buffer overflows.

Gernot Heiser presents seL4, a microkernel with a mathematical proof connecting security properties to the binary code, and explains what its open-sourcing means for users. It covers its roles as a microkernel, separation kernel and hypervisor.
