Some operating systems ask you to trust them. OpenBSD earns it. I've spent my career in the trenches of information security — hardening systems, closing attack surfaces, and building infrastructure that doesn't apologize for being locked down. OpenBSD didn't just become my tool of choice. It became my standard. The OpenBSD Engineer's Handbook is what I wish someone had handed me years ago: a no-nonsense, engineer-first guide to one of the most secure and thoughtfully designed operating systems on the planet. Not a quick-start. Not a wiki dump. A real handbook — the kind you reach for when things get serious. Inside, you'll find everything from pf firewall design and privilege separation to production-grade networking, secure development workflows, and the operational discipline that separates good systems from bulletproof ones. If you're done with security theater and ready to build something that actually holds — this is your book.

Next-Gen Surveillance: A Practical Guide to Modern Security Systems for Home & Business provides a comprehensive, step-by-step guide for anyone looking to secure their property with modern technology. Written by an experienced engineer with hands-on experience designing personal home security systems, this book covers everything from fundamental principles to advanced AI-driven surveillance.

After more than twenty years at IBM — including roles as Regional Technical Leader for Security Technologies and Tivoli Software across Central and Eastern Europe — I have seen many SOC modernization projects. Organizations consistently face the same dilemma: substantial existing investments in SIEM, SOAR, processes, and human expertise versus the urgent need to keep pace with AI-powered threats.Most vendors pushed rip-and-replace cloud solutions. I took a different path.The Brownfield Agentic SOC concept was born from the realization that modernization does not require replacement. It is possible — and often far more effective — to intelligently augment existing infrastructure with multi-level AI agents, dynamic business context, structured investigation, and strong governance, while preserving data sovereignty and human judgment.This book is intentionally practical and conceptual. Certain advanced techniques (self-healing patterns, zero-visible-downtime adaptation, tamper-evident intelligent audit) are subject to pending patent protection and are presented here at architectural level only.I wrote this book for three audiences:CISOs and SOC leaders in regulated industries seeking realistic modernizationSecurity architects responsible for next-generation operationsTeams that prioritize sovereignty, compliance, and human-AI collaborationMy goal is to provide a clear, actionable blueprint that respects real-world constraints while delivering measurable improvement.I hope this book inspires and equips you to build more resilient, intelligent, and sovereign Security Operations Centers.Zsolt L.

Modern cybersecurity is no longer just about firewalls and antivirus. It is about architecture, governance, secure software delivery, cloud resilience, Zero Trust, AI security, and operational discipline.The Master Guide to Cyber Security brings these domains together into one practical enterprise-focused reference designed for modern security professionals, architects, engineers, and technology leaders.Built around real-world frameworks, secure-by-design principles, and current threat realities, this guide provides a structured roadmap for building secure systems in cloud-native and enterprise environments.
