Computing Security Pioneer Peter Neumann Dies at 93

Peter Neumann's death marks the loss of a foundational architect of computer security whose influence spans decades. For over 40 years, his RISKS Digest meticulously documented system failures and their real-world consequences, establishing how the computing community understands technology vulnerabilities. His contributions—from co-designing Multics to pioneering CHERI's capability-based security architecture—directly shaped how modern systems are built to prevent catastrophic failures.
