The pace of change including the rise of artificial intelligence and a sense of accelerating chaos can make cybersecurity professionals feel like "things are kind of everything, everywhere, all at once," said Black Hat conference founder Jeff Moss. How should they respond?

Many important efforts by the Cybersecurity Infrastructure and Security Agency to help the healthcare sector and other critical infrastructure sectors bolster their cybersecurity are likely to continue under the incoming Trump administration, predicted CISA Deputy Director Nitin Natarajan.

The first 100 days of the next Trump administration and new Congress will be critical in showing signs of what's potentially in store for the healthcare sector cybersecurity, privacy and related regulatory and legislative issues in the new year, said Chelsea Arnone and Cassie Ballard of CHIME.

As healthcare entities embrace generative AI tools, it's critical they take a holistic approach addressing privacy and security governance, said Dave Perry, digital workspace operations manager, St. Joseph's Healthcare in Ontario, who discusses how his organization is tackling those challenges.

Fully homomorphic encryption can safeguard highly sensitive health data related to rare diseases, underserved populations and clinical trials as it is shared with medical researchers, said Kurt Rohloff, co-founder and CTO of Duality Technologies, who said projects to apply it are underway right now.

Cyber incident details involving non-profit and non-government entities across sectors such as healthcare are not centrally reported and collected, creating gaps for researchers, IT experts and others seeking to analyze trends in their industries, said Stanley Mierzwa of Kean University.

One of the most important lessons emerging in 2024 for the healthcare sector is that entities should diligently prepare contingency plans for potential cyberattacks that seriously disrupt their critical third-party vendors, advises regulatory attorney Betsy Hodge of the law firm Akerman.

Washington and Nevada were among states enacting new data privacy laws in 2024, and that trend among states will likely continue into 2025 as the next presidential administration comes into office promising to reduce federal regulations, said attorney Melissa Crespo of law firm Morrison Foerster.

About 75% of healthcare sector entities that suffered a ransomware attack over the past year were targeted on a weekend or holiday, highlighting the need for organizations to bolster staffing and related strategies during these vulnerable times, said Jeff Wichman of security firm Semperis.

The torrents of public hostility directed at health insurers in the aftermath of UnitedHealthCare CEO Brian Thompson's murder are serious signs of intensifying cyber and physical threats facing the C-suites of healthcare and many other sectors, said Chris Pierson, founder and CEO of BlackCloak.

Hackers can potentially use AI to manipulate data that's generated and shared by some health apps, diminishing the data's accuracy and integrity, said Sina Yazdanmehr and Lucian Ciobotaru of cybersecurity firm Aplite, describing a recent research project involving Google Health Connect.

Third-party access management poses significant cybersecurity risks in healthcare, but continuous identity management and monitoring can help mitigate those risks, said Jim Routh, chief trust officer at Saviynt.

Thousands of unique IP addresses are potentially exposing medical devices, electronic medical records systems and other sensitive healthcare information to the internet, said security researcher Himaja Motheram of security firm Censys, which made the discovery.

It goes without saying: Business ecosystems are increasingly complex, and so are the cybersecurity systems and strategies deployed to protect them. But Marty McDonald of Optiv and Rob Rachwald of Palo Alto Networks share new ideas on how to take some of the complexity out of cybersecurity.

When a large hospital in an urban area is shut down by ransomware, the disruption can be significant, but when a rural hospital faces a similar cyber outage, the impact on patient safety and the community can be extreme, said Nitin Natarajan of the Cybersecurity and Infrastructure Security Agency.

While ransomware attacks against medical devices don't happen often, disruptive cyber incidents that affect the availability of the IT systems that medical devices rely on are a big concern that needs the industry's critical attention, said Jessica Wilkerson of the FDA.

It's crucial for healthcare sector organizations to vet their artificial intelligence tech vendors in the same robust way they scrutinize the privacy and security practices of all their other third-party suppliers, said attorney Linda Malek of the law firm Crowell & Moring.

Healthcare organizations should rethink some of their approach to security, enhancing focus on insider threats, improving cyber awareness training and securing mobile applications and devices, said Ryan Witt, vice president of industry solutions at Proofpoint, discussing findings of a new study.

It's yet to be determined whether a handful of states or the federal government will lead the charge in adopting comprehensive regulations involving the use of artificial intelligence in healthcare, said regulatory attorney Betsy Hodge, a partner in law firm Akerman.

As threat actors continue to evolve their attacks to circumvent security measures, cyber insurers are raising the bar for prospective healthcare security clients. Underwriters are increasing their scrutiny and adding new coverage requirements, said Chris Henderson of cybersecurity company Huntress.
