More and more, mobile equipment is a working tool everywhere. The operating system is a fundamental component of the protection strategy, that is, by improving the operating system, we are contributing to more reliable equipment. One of the techniques of the authors’ approach is to strengthen the operating system (OS) kernel for mobile devices: deep mobile OS security (DMOS).

This is a technical, informative paper, where the authors analyze defense techniques and their effects related to resilience. The authors evaluate cyber resilience characteristics during an attack cycle. The paper is well organized, with sections describing the cyber resilience framework, DMOS techniques, an evaluation of these techniques, and a testbed consisting of smartphones and a server for management. The paper would be better if it provided more information on other OS security techniques and how they compare with DMOS.
