I was recently attending a panel discussion between manufacturers in the food & beverage, pharmaceutical and public utility sectors when a question was asked about the efforts the companies have made around track and trace and security. Two of the panelists said they rely on air gapping to maintain security, and track and trace is done through a homegrown system or an existing manufacturing execution system (MES).
Then a representative from a large pharmaceutical company chimed in and noted that security between the business network and the production network relied solely upon a firewall.
