Critical Controls for OT Cybersecurity in Pharmaceutical Manufacturing

This guide outlines five critical controls necessary for effective operational technology (OT) cybersecurity specifically tailored for the pharmaceutical manufacturing sector. It begins by emphasizing the importance of executive alignment in establishing a robust cybersecurity framework. The document details strategies for communicating risks to the board, including using real-world scenarios and historical data from previous attacks. Following this, it discusses the necessity of collaboration between IT and OT teams to enhance security measures. The five critical controls are then presented: an ICS incident response plan, a defensible architecture, visibility and monitoring of assets, secure remote access, and risk-based vulnerability management. Each control is elaborated upon, highlighting the unique requirements of OT environments compared to traditional IT systems. The guide concludes by stressing the importance of technology and personnel in implementing these controls effectively.
