Containment As A Core Security Strategy
DARKReading, Monday, July 21st, 2025
We cannot keep reacting to vulnerabilities as they emerge. We must assume the presence of unknown threats and reduce the blast radius that they can affect.
In nuclear safety design, isolation is everything. When containment fails, so does the system. At Chernobyl, isolation protocols were bypassed to achieve a performance goal. When the reactor overheated, there was no effective barrier to prevent cascading failure.
The event was not just a technical malfunction but a systemic failure in enforcing hard limits. The Fukushima disaster was similarly escalated not by the initial earthquake but by a loss of containment. Flooded backup generators disabled cooling systems, causing overheating that breached the core.
