Designing OT Networks to Contain Breaches, Not Pretend They Won’t Happen

Assuming perfect prevention is not a strategy.

This principle focuses on blast-radius reduction, a concept CISOs understand well.

Board-Level Risk Controls

• Segmentation and micro-segmentation

• Separation of duties

• Elimination of flat networks

• Restrictions on lateral movement

Executive Insight

Resilience is defined by how much damage an attacker can cause after initial access.

Final Thought: Resilience Is About Containment, Not Confidence

No CISO should assume their OT environment is uncompromised—only that compromise has not yet been detected. Segmentation and blast-radius reduction acknowledge this reality without accepting defeat.

Boards rarely ask whether a breach is possible; they ask how bad it will be. CISOs who design networks to fail safely provide credible answers when those questions come.

Generative AI Governance: Using the NIST Framework to Build Trust, Reduce Risk, and Lead Secure AI Adoption

Generative AI has moved faster than nearly any technology security leaders have dealt with. Tools that can generate text, code, images, and data insights are now embedded into productivity platforms, security tooling, development workflows, and business operations—often before security teams are formally involved. For CISOs, this creates a familiar but amplified challenge: innovation is happening faster than governance, and unmanaged generative AI introduces material risk across confidentiality, integrity, availability, compliance, and trust. For aspiring information security professionals, AI governance represents a growing and valuable discipline where strategic thinking matters just as much as technical depth. The good news? We don’t need to invent governance from scratch. NIST’s AI Risk Management Framework (AI RMF) provides a practical, flexible structure that security leaders can use today to govern generative AI responsibly and defensibly. Why Generative AI Governance Matt...

White House National AI Policy Framework: What CISOs Need to Know and Do Now

The White House released its National Policy Framework for Artificial Intelligence on March 20, 2026, and every CISO needs to read past the headlines. The document is not a law. It is not a regulation. It is a set of legislative recommendations directed at Congress — non-binding by design — outlining how the Trump administration believes the federal government should approach AI governance. What it is, practically speaking, is the clearest signal yet of where federal AI policy is headed and how that trajectory should reshape your organization’s approach to AI risk management, compliance planning, and governance program design. The framework follows Executive Order 14365, signed in December 2025, which directed federal agencies to identify and challenge state AI laws that conflict with national AI strategy. Together, these actions set up the central tension that enterprise security leaders now have to navigate: a federal posture that is explicitly moving toward preempting state-level AI...
