Peter G. Neumann, Who Warned of Computer Security Risks, Dies at 93

Peter G. Neumann, one of the earliest voices warning about computer security and privacy risks, has died at 93. For decades, he pushed back against the tech industry's casual approach to building secure systems, long before data breaches and privacy scandals became regular headlines.

Neumann didn't just criticize. He developed actual solutions and frameworks for building more secure software. His work at SRI International influenced how we think about system reliability and security architecture today.

His warnings feel especially relevant now as AI systems get deployed at scale. The same security and privacy issues he flagged in traditional software, like insufficient testing and poor access controls, apply to AI systems too. Except now the stakes are higher because these systems make autonomous decisions.

For anyone building or deploying AI tools, Neumann's core message still holds. Security and privacy can't be afterthoughts. They need to be baked into system design from the start, not patched in later when something breaks.

The tech industry has slowly come around to his perspective, though often only after major incidents prove him right. His legacy is a reminder that the fundamentals of secure system design don't change just because the technology gets fancier.
