The final installment of a blog series on red teaming from a CISO's perspective delves into the application of red teaming in the manufacturing and industrial sectors, highlighting the unique cyber threats these environments face. It discusses how nation-state actors, ransomware gangs, and corporate espionage pose significant risks, especially due to the reliance on legacy technology and weak security in operational technology (OT) environments. The series emphasizes the importance of bridging IT and OT security through red team engagements, which simulate various attack scenarios such as IT-to-OT pivot attacks, data exfiltration, ransomware spread, and physical intrusions, aiming to uncover vulnerabilities and improve incident response strategies. These exercises are crucial for identifying security gaps, enhancing network segmentation, securing sensitive intellectual property, and ensuring robust incident response mechanisms that involve coordination across IT and OT domains. The series concludes by encouraging organizations to explore red teaming to bolster their cybersecurity defenses.
