How 9 11 Built the Cybersecurity World | Huntsville News

On the morning of 9/11, Marcus Sachs found himself in a Pentagon briefing meant for classified military cyber defense—only to be thrust into a moment that would redefine national security. As hijacked planes struck the Twin Towers and the Pentagon, Sachs realized his survival depended on a mere change in schedule, exposing how unprepared we were for hybrid physical and digital threats. In the aftermath, the U.S. scrambled to build cyber defense from scratch, with Sachs helping draft the first national cyber strategy and later leading DHS’s cyber programs. What began with three people evolved into the sprawling Cybersecurity and Infrastructure Security Agency, protecting everything from power grids to elections. But with 85% of critical infrastructure privately owned, true security demands constant public-private collaboration. Looking ahead, Sachs warns that the greatest threats now lie in emerging tech like AI—not planes, but algorithms that could outpace our defenses. The lesson? Prepare for the unknown, because the next attack might not even be on our radar. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
