John Frushour, vice president and CISO, New York-Presbyterian Hospital, and CyberEdBoard member Healthcare organizations should focus on practical quantum readiness rather than fear-driven predictions about sudden cybersecurity disruption, said John Frushour, vice president and CISO of New York-Presbyterian Hospital. Quantum-resistant technologies already exist through standards and encryption methods that many organizations can access today. Preparing for Q-Day is achievable without dramatic operational changes, he said. Healthcare leaders, along with organizations in other regulated sectors, continue to monitor post-quantum cryptography while balancing present-day security priorities, he said. Commercial software and service providers play a significant role in helping enterprises adopt quantum-resistant capabilities, Frushour said. In addition, healthcare organizations will potentially benefit by long-term opportunities quantum computing creates through advanced computation, stronger encryption and the ability to analyze anonymized data more effectively, he said during an ISMG interview conducted at the recent HealthSec conference in Boston. "I think first of all - just be wary of the hype, as with anything in cybersecurity, but also be prepared for the future," he said. "Ensure that if you can get on your load balancers or your hosted infrastructure, if you can get to strong TLS 1.3 and strong ciphers, get there. You're probably not going to break anything by doing so," he said. In this audio interview (see link below photo), Frushour also discussed: Post-quantum cryptography readiness and how National Institute of Standards and Technology guidelines help; Quantum risks involving healthcare and biomedical devices; How artificial intelligence combined with quantum computing could improve security forecasting. Frushour, who joined New York-Presbyterian Hospital in 2016, previously held several security management and leadership roles at technology firms, including Nuance, where he served as director of security operations. Prior to that, he held technology management positions in the U.S. Marine Corps, including director of tactical networks. He is a member of the CyberEdBoard.
