This article is the last in a series that discusses the challenges that IT departments face when they are assigned the task of overseeing cybersecurity in factories and implementing measures to overcome these challenges. As explained in the first two articles, a factory network that accounts for diverse conditions and environments requires a well-balanced consideration of security in view of the actual operational situation, namely because applying uniform security policies to such a network is difficult compared to IT.
