Bilfinger’s Benjamin Bachmann explains why industrial security requires moving beyond the myth of air-gapped networks to focus on operational resilience, network visibility, and pre-negotiated incident response strategies.

Key Points

• Industrial attackers prioritize controlling physical operations and halting production over traditional data theft.
• The "air gap" is largely a myth, as most industrial environments contain unauthorized connections like forgotten LTE dongles.
• Security teams should treat OT networks as predictable "choreography" rather than chaotic IT traffic to identify anomalies.
• Effective defense relies on pre-negotiated containment plans that avoid unnecessary production shutdowns during security incidents.
• Organizations should prioritize rapid recovery and degraded operation capabilities to neutralize the financial leverage of ransomware groups.
• Security architecture must prevent simple user errors, such as phishing clicks, from reaching critical controllers like turbines.

Why it Matters

Shifting the focus from data protection to operational continuity helps industrial firms better align security investments with physical safety and uptime requirements. This approach forces organizations to build resilient architectures that remain functional even during a cyberattack, effectively undermining the business model of modern ransomware actors.
