  Cyber-physical systems are becoming core of the most modern systems
consisting control, data sharing and real-time monitoring. While centralized
control technique has been implemented in the past, recent innovation in
distributed control schemes makes it attractive due to various reasons. One of
them is the use of state-of-the-art communication protocols that makes the
system more robust toward extreme conditions and ensures observability. Thus,
as an application of cyber-physical systems, distributed control architectures
are prone to various cyber-vulnerability which makes cybersecurity research
critical in this application domain. This paper reviews recent researches of
distributed control architectures, their cyber-vulnerabilities, and reported
mitigation schemes. Finally, some research needs are addressed.
