Municipalities are tasked with ensuring the cybersecurity of critical public services and functions in diverse areas such as safe water supply, healthcare, child protective services, and education with vastly different security requirements—all usually served from a common infrastructure with limited technical and organizational cybersecurity capabilities. This literature review identifies recent research on municipal and local government cybersecurity to identify current research areas, state of the art, and research methods used in research so far. We found research in the areas of smart cities, elections, human factors, operational technology, and crisis management. We also give suggestions for further research to develop better models for cybersecurity in cross-disciplinary organizations.
