Why Is Cybersecurity Important to Healthcare
Healthcare delivery organizations—including hospitals, acute care facilities, urgent care clinics, and doctors’ offices—depend heavily on digital technology for various clinical, diagnostic, and business functions.
Digital technology is also crucial for ensuring the smooth operation of critical healthcare infrastructure, such as power systems, HVAC, and communications. Furthermore, numerous smart, connected devices, such as medical IoT devices (collectively known as the Internet of Medical Things or IoMT), are deeply integrated into healthcare providers’ digital ecosystems.

This extensive reliance on digital technology involves a vast array of hardware, software, and cloud services, all of which present potential targets for hackers. Whether motivated by financial gain, disruption of essential healthcare services, or other reasons, cyberattacks pose a significant threat to every aspect of care delivery. As a result, cybersecurity has become an essential priority for healthcare leaders.
Elements of Healthcare Cybersecurity
Healthcare cybersecurity involves ensuring that care delivery organizations have the proper strategies, processes, technologies, and personnel to identify and assess threats, prevent them from disrupting healthcare operations, and recover fully and swiftly if an attack occurs.
Moreover, healthcare security encompasses external considerations such as regulatory compliance, legal obligations, and the organization’s brand reputation.
1. Protect Patient Data
A primary objective of healthcare cybersecurity is safeguarding patient data. Protected health information (PHI) and personally identifiable information (PII) are prime targets for hackers, making it critical for any healthcare cybersecurity strategy to prioritize their protection.
2. Secure IoMT Devices
Smart, connected devices like infusion pumps, heart monitors, air filtration systems, and water purification pumps form an integral part of healthcare operations.
Although these devices come with basic cybersecurity measures, their limited memory capacity restricts their security capabilities. Healthcare cybersecurity teams must implement additional layers of protection to secure these devices effectively.
3. Ensure Continuity of Services
Healthcare services must remain reliable and uninterrupted during a cyberattack, whether the target is patient data or medical operations. A comprehensive business continuity plan is essential for any healthcare cybersecurity strategy. This plan should include hardware failover, data recovery, and backups stored in off-site systems or cloud platforms.
HIPAA Security Rule
The Health Insurance Portability and Accountability Act (HIPAA) Security Rule, introduced in 2005, came nine years after the U.S. Congress passed HIPAA. According to the U.S. Department of Health and Human Services, the Security Rule sets national standards to safeguard individuals’ electronic personal health information (ePHI) that is created, received, used, or maintained by a covered entity. It operates as a subset of the HIPAA Privacy Rule, which outlines standards for the protection of PHI.

Healthcare Data Breaches
The U.S. Department of Health and Human Services (HHS) defines a data breach as an unauthorized use or disclosure under the Privacy Rule that jeopardizes the security or privacy of protected health information (PHI). Data breaches can arise from a wide and increasing variety of causes, including:
- Ransomware
- Email attacks, such as phishing and social engineering
- Credentials theft
- Irregular or missed security patches
- Theft of physical devices, including laptops, tablets, phones, and smart cards
- Identity theft
- Systems failures, such as infrastructure misconfigurations
- Insider attacks carried out by disgruntled employees
- Human error
Healthcare Business Continuity
Business continuity refers to an organization’s ability to maintain essential operations during unforeseen events such as natural disasters, human error, or cyberattacks. While crucial for any organization in any industry, the impact of service disruptions on day-to-day healthcare operations is particularly significant and potentially catastrophic.
Hospital Data Security
In hospitals, continuous operations are critical, and systems, processes, and protocols must be in place to manage disruptions. Hospital data security involves a wide range of issues, including:
- Protecting traditional IT infrastructure such as endpoints, servers, networks, and applications
- Securing smart, connected devices like IoMT devices and other digitally controlled critical systems
- Implementing physical security measures to prevent device theft or unauthorized access to facilities
- Complying with regulatory, legal, and data governance standards relevant to the hospital
Protected Health Information (PHI)
Protected health information (PHI) refers to any information that must be secured to ensure a patient’s healthcare privacy. Regulations require covered entities — individuals or organizations providing healthcare — to protect information related to a patient’s physical or mental health, both past and present. A patient’s health plan must ensure reliable and consistent protection of PHI.
As defined by HIPAA and its Privacy Rule, PHI includes “individually identifiable information transmitted by electronic media, maintained in electronic media, or transmitted in any other form of media.”
Over the past 20 years, the scope of PHI has steadily expanded. As technology advances in capturing, storing, and sharing PHI, and as regulations evolve, the scale and complexity of PHI will continue to grow.
Key Challenges in Healthcare Cybersecurity
Ensuring effective, reliable, and efficient healthcare cybersecurity is a collaborative effort that requires involvement from everyone in the organization. The threat landscape is constantly evolving, and it’s crucial for all staff members to stay informed about the latest attack methods.
1. Employee Training
As hospitals and care organizations expand their workforce, they must dedicate more time to training employees on essential topics such as regulatory compliance related to PHI and PII.
This training should be included in the onboarding process for new employees and should also be ongoing to reinforce best practices and keep staff updated on emerging threats and regulatory changes.
2. Regulatory Compliance
Healthcare “covered entities” are required to comply with HIPAA’s standards, which have been updated and expanded multiple times since 1996. Failure to adhere to these regulations can lead to fines or other sanctions by the U.S. Department of Health and Human Services.
In addition, healthcare organizations must comply with other privacy regulations, such as Europe’s General Data Protection Regulation (GDPR) and similar laws in the U.S. that protect patient information.
3. Rapid Digital Transformation
Digital transformation plays a critical role in healthcare, as organizations seek ways to improve patient outcomes and increase revenue. However, this shift has also resulted in the adoption of a wide range of new devices, applications, and services, each of which can be a potential target for cyberattacks.
The Future of Healthcare Cybersecurity
Healthcare cybersecurity will continue to grow in complexity, making it increasingly vital. As the threat landscape evolves at an unprecedented pace, it is crucial to partner with trusted technology providers and advisors who can enhance their defenses.
Many organizations also face a shortage of cybersecurity talent, which makes outsourcing certain aspects of cybersecurity defense planning, implementation, monitoring, and management a necessity.
Furthermore, organizations must allocate sufficient budgetary resources for tools, systems, and services to reinforce both external and internal systems against the rapidly growing threats.
