The healthcare sector needs a 911-style cyber civil defense system that can help all segments of the industry, including under-resourced groups, to more rapidly and effectively respond to cyberattacks and related incidents, said Erik Decker, CISO of Intermountain Health and a federal cyber adviser.

Your supply chain is your new attack surface, according to Galit Lubetzky Sharon, the co-founder and CEO of Wing Security. She discusses Wing's solution - Secure SaaS Posture Management, or SSPM - that helps organizations ensure that all of their SaaS apps are safe and compliant.

CISO Sam Curry and CMO Red Curry discuss the chaos and disruption of cyberwar and how attacks on critical infrastructure can tactically help attackers in combat, demoralize the general population and affect critical capabilities at just the right point in time.

The Biden administration's strategy for bolstering health sector cybersecurity, which includes newly released voluntary cyber performance goals and plans to update the HIPAA Security Rule, is fueling uncertainty in some organizations, said privacy attorney Iliana Peters of law firm Polsinelli.
