Microgrids are growing in importance in the Smart Grid paradigm for power systems.
Microgrid security is becoming crucial since these systems increasingly rely on information and
communication technologies. Many technologies have been proposed in the last few years for
the protection of industrial control systems, ranging from cryptography, network security, security
monitoring systems, and innovative control strategies resilient to cyber-attacks. Still, electrical
systems and microgrids present their own peculiarities, and some effort has to be put forth to apply
cyber-protection technologies in the electrical sector. In the present work, we discuss the latest
advancements and research trends in the field of microgrid cybersecurity in a tutorial form
