Articles on security architecture, graph theory, risk economics, and the structural patterns that connect technology to business outcomes.
The firewall-first mindset creates fragile networks that collapse on breach. Designing firewall-last forces you to build self-defending nodes, prune unnecessary connections, and treat the perimeter as defense in depth—not a structural dependency.
Every vendor is selling Zero Trust. None of them are selling graph databases. That's the problem. You can't determine 'necessary edges' without mapping your current graph—and no identity proxy solves that.
The Kill Chain shows attacks as linear progressions. Real attacks loop through lateral movement, branch based on what they find, and restart tactics on every new system. Graph theory models what linear frameworks can't.
The Spartans built the perfect defensive chokepoint—and were destroyed by a path they didn't know existed. Graph theory reveals why perimeter security fails and what modern defenders must do instead
You cannot optimize what you cannot measure. Security teams ask graph theory questions—attack paths, blast radius, chokepoints—but use tools built for lists. Here's why that gap is costing you.
Risk owner' sounds like a real role, but it's often just a name in a cell. True responsibility requires personal stakes: authority to act, accountability for outcomes, and capability to execute. Here's how to move from documentation to action.
The Iron Triang le gives teams a convenient excuse for failure. The 3R Optimization Model—Revenue, Resources, Risk—forces them to do the math. Here's why marginal analysis beats binary trade-offs.
The optimal security investment isn't where cost equals risk—that's a common misconception. It's where the next dollar spent reduces risk by exactly one dollar. Here's how marginal analysis changes security decision-making.
