Zachary Eikenberry: Psychological Security

Modern cybersecurity is dominated by tools, audits, and compliance checklists — yet most breaches still begin with predictable human behavior. Technology has advanced, but the assumptions behind how organizations train, support, and expect people to behave have not.

Psychological Security explains why human behavior is the central factor in modern cyber risk and why technical defenses fail when the systems around people ignore how the brain actually works. Drawing from research in psychology, neuroscience, and education, as well as years of behavioral data from real security environments, Zachary Eikenberry outlines a practical model for reducing risk by redesigning the conditions that shape decision-making.

This book examines:

• Why people make insecure choices even when they know better

• How cognitive load, emotional state, habit formation, and environmental design influence security behavior

• Why traditional training fails — and what an evidence-based alternative looks like

• How leadership, incentives, and culture determine security outcomes

• How decentralization, AI, automation, and remote work change the human attack surface

• What organizations must do to build consistent, resilient security habits at scale

Psychological Security is not about blaming users or selling tools. It is about understanding security as a behavioral system — one that can be intentionally designed. For leaders, security teams, and anyone responsible for organizational risk, this book offers a clear, grounded framework for building security programs that work with human nature rather than against it.
