Open Source and Cyberdéfense A strategic, doctrine-oriented essay on sovereignty, resilience, and operational security using open-source foundations—especially for OT/ICS and critical infrastructure. Scope & intent. This text focuses on defensive architecture, governance, and resilience engineering. It argues that open source is not merely a cost-saving choice: it can be a strategic instrument of cyberdéfense when integrated with disciplined operations, secure supply chains, and mission-driven governance. Table of contents 1) Doctrinal thesis: open source as strategic terrain 2) Sovereign architecture: from code transparency to operational authority 3) Threat matrices for open-source-driven defense 4) Reference architecture for OT/ICS cyberdéfense (open stack) 5) Governance, compliance, and procurement doctrine 6) Adoption roadmap & readiness checklist References (numbered) 1) Doctrinal thesis: open source as strategic terrain In cy...

The Strategic Role of Analog Electronics in OT/ICS Cyber Defense The Strategic Role of Analog Electronics in OT/ICS Cyber Defense A doctrinal military essay with threat matrices, attack scenarios, and documented historical cases (energy, defense, hospitals, SCADA). Scope & intent. This text focuses on cyber-physical resilience in Operational Technology (OT), Industrial Control Systems (ICS), and critical infrastructures. It argues that analog electronics are not “legacy leftovers” but a sovereign, non-software layer of authority that can constrain or outlast digital compromise. Table of contents 1) Doctrinal thesis 2) A hybrid sovereign architecture (analog → digital → cyber) 3) Threat matrices for OT/ICS 4) Attack scenarios (operational narratives) 5) Documented historical cases 6) Operational implications ...
