“…A survey of EU research efforts in the security solutions of ESs has been done in [85], where security solutions for ESs were classified to several levels: (i) Node-based security technologies, for example a physical unclonable function (PUF), a physically-defined "digital fingerprint" that serves as a unique identity [31]; and (ii) network-based security technologies, focusing on secure routing and Intrusion Detection System (IDS) for a distributed ES network, implemented with middleware and overlay technologies. Among the studies that dealt with security solutions is also a preemptive security mechanism, which is a thin-layer hypervisor-based memory introspection engine on ESs and was proposed by Lukacs et al [86]. The concept of this mechanism is based on hardware virtualization technology, and this mechanism works on two different levels: privilege level and isolation; and hardware-level virtualization.…”

To identify the key factors and create the landscape of cybersecurity for embedded systems (CSES), an analytical review of the existing research on CSES has been conducted. The common properties of embedded systems, such as mobility, small size, low cost, independence, and limited power consumption when compared to traditional computer systems, have caused many challenges in CSES. The conflict between cybersecurity requirements and the computing capabilities of embedded systems makes it critical to implement sophisticated security countermeasures against cyber-attacks in an embedded system with limited resources, without draining those resources. In this study, twelve factors influencing CSES have been identified: ( 1) the components; (2) the characteristics; (3) the implementation; (4) the technical domain; (5) the security requirements; (6) the security problems; (7) the connectivity protocols; (8) the attack surfaces; (9) the impact of the cyber-attacks; (10) the security challenges of the ESs; (11) the security solutions; and(12) the players (manufacturers, legislators, operators, and users). A Multiple Layers Feedback Framework of Embedded System Cybersecurity (MuLFESC) with nine layers of protection is proposed, with new metrics of risk assessment. This will enable cybersecurity practitioners to conduct an assessment of their systems with regard to twelve identified cybersecurity aspects. In MuLFESC, the feedback from the systemcomponents layer to the system-operations layer could help implement "Security by Design" in the design stage at the bottom layer. The study provides a clear landscape of CSES and, therefore, could help to find better comprehensive solutions for CSES.INDEX TERMS Characteristics of embedded system, countermeasures, embedded system, cybersecurity of embedded system, MuLFESC, risk assessment.
