The following is a guest article by Oren Koren, Co-Founder and CPO at Veriti
In 2024, the healthcare sector emerged as a prime target for cybercriminals, with the medical and personal data of over 170 million U.S. citizens compromised in a wave of unprecedented breaches. From the Change Healthcare ransomware attack that exposed the personal and health information of over 100 million individuals to even one of the more recent attacks on Texas Tech University that leaked 2.1 million files of stolen data – both of which underscore the urgency to intensify cyber defense strategies. The sensitive nature of healthcare data, coupled with the sector’s rapid technological advancements, has created a perfect storm for vulnerabilities. As cybersecurity professionals, our mandate is clear: we must proactively address the shifting healthcare threat landscape. This involves tackling Internet of Things (IoT) vulnerabilities, ensuring secure cloud adoption, and safeguarding against risks associated with AI-driven technologies.
2025 Healthcare Security Strategies
Addressing IoT Vulnerabilities
The proliferation of IoT devices in healthcare has revolutionized patient care and operational efficiency. From connected medical devices to smart hospital systems, these technologies offer immense benefits, as well as introduce significant security risks. Many IoT devices were not designed with cybersecurity in mind, making them prime targets for attackers.
To mitigate these risks, healthcare organizations should adopt a multi-faceted approach. First, conduct comprehensive audits of all IoT devices within the network to identify potential vulnerabilities. Implementing network segmentation can help isolate these devices, reducing the impact of a potential breach. Additionally, regular firmware updates and patch management are crucial in closing security gaps. Investing in robust endpoint security solutions tailored for IoT can further enhance protection.
Ensuring Secure Cloud Adoption
Recent estimates show that migration to cloud services has accelerated within the healthcare sector, driven by the need for scalable, cost-effective solutions. While cloud adoption offers numerous advantages, it also presents new security challenges. Data breaches in cloud environments often stem from misconfigurations, insufficient access controls, and inadequate monitoring.
Hospitals and other healthcare institutions must prioritize secure cloud adoption strategies. This begins with selecting reputable cloud service providers that comply with healthcare-specific regulations, i.e. HIPAA. Implementing strong access control measures, including multi-factor authentication (MFA) and role-based access controls (RBAC), is essential to limit unauthorized access. Regularly reviewing and updating security configurations can prevent common missteps that lead to breaches. Moreover, continuous monitoring and employing cloud security posture management (CSPM) tools can help detect and remediate vulnerabilities in real time.
Safeguarding Sensitive Data Exposed by AI-Driven Technologies
AI-driven technologies are transforming healthcare, from predictive analytics to personalized medicine. However, these advancements come with inherent risks, particularly concerning the protection of sensitive data like personally identifiable information (PII) and patient records. AI systems require vast amounts of data to function effectively, increasing the potential attack surface.
To protect sensitive data, organizations should adopt a privacy-by-design approach in their AI initiatives. This involves embedding data protection measures into the development and deployment of AI systems. Data anonymization and encryption are critical in ensuring that even if data is accessed unlawfully, it remains unintelligible to unauthorized parties. Implementing robust data governance frameworks can help manage data access and usage, ensuring compliance with regulatory standards.
It’s also crucial to monitor AI systems for biases and vulnerabilities that could be exploited. Regularly updating AI models and algorithms with the latest security patches can prevent the exploitation of known vulnerabilities. Partnering with cybersecurity experts to conduct thorough risk assessments of AI systems can further strengthen their resilience against attacks.
A Proactive Cybersecurity Imperative
The healthcare sector’s reliance on emerging technologies necessitates a proactive and comprehensive approach to cybersecurity. By addressing IoT vulnerabilities, ensuring secure cloud adoption, and safeguarding sensitive data in AI-driven technologies, we can strengthen healthcare systems against major cyber attacks like we saw in 2024. As security professionals, our role is to not only respond to incidents but to anticipate and mitigate risks before they materialize. By staying ahead of the curve, we can protect the invaluable data and systems that underpin modern healthcare.
