"How can you tell a computer is an ICS?... It's at least 20 years old."
"Once the humor passes and the reality sets in, the scale of the problem - an entrenched ecosystem with the inertia of security challenges baked in for years - becomes apparent.."
"Something that was designed and tested to the best practices available when it was released can easily become vulnerable to attacks using more sophisticated attacks later in its lifecycle,"
"ICS security problems will unfortunately persist in 2026 because the core challenge is both economic and operational. Critical infrastructure operators simply cannot accept downtime for comprehensive overhauls, and legacy systems with 20- to 30-year lifespans weren't designed for today's cyber thre"
Industrial Control Systems were designed for stable, non-adversarial environments but now operate amid continuous cyber conflict, creating pervasive security gaps. Many ICS components are decades old and adhere to legacy best practices that are inadequate against modern sophisticated attacks. Operators often cannot accept downtime, which prevents comprehensive patching, upgrades, or system overhauls. Economic and operational constraints extend the use of 20– to 30-year lifespans for systems lacking contemporary security features. The entrenched ecosystem and operational inertia compound risk, making remediation complex and increasing the likelihood of successful attacks into 2026. Strategies balancing resilience and minimal disruption are essential.
