The digital revolution has made people more dependent on ICT technology to perform everyday tasks, whether at home or at work. The systems that support critical aspects of this smart way of living are characterized as critical, and the security level of such systems is higher as compared to others. The definition of the criticality of a system is a rather difficult exercise, and for that reason, we have seen novel cybersecurity regulations to introduce the idea of digital managed services, which include security monitoring, managed network services, or the outsourcing of business processes that are are critical to the functioning, reliability, and availability of Critical National Infrastructures (CNIs). Moreover, ENISA recently issued a new report that deals with supply chain attacks. Those attacks target any chain of the ecosystem of processes, people, organizations, and distributors involved in the creation and delivery of a final solution or product that can be used or incorporated into a CNI, thus further extending the scope of the security posture of a system.
