What Is Healthcare Cybersecurity?
Trend Micro protects healthcare data with AI-powered security across endpoints, networks, and the cloud—so you can focus on patient care.
What Is Healthcare Cybersecurity?
Healthcare cybersecurity is the practice of protecting healthcare systems, devices, and sensitive patient data from cyber threats. Serving a sector where data and care go hand in hand, cybersecurity needs to be particularly strong in healthcare.
The impact of cyber attacks on the NHS and other healthcare providers has shown how real the stakes are: delayed treatments, emergency service disruptions, and compromised patient trust. This page explores what makes healthcare systems vulnerable—and what industry leaders can do about it.
Why Is Healthcare a Prime Target for Cyber Attacks?
Cybercriminals are drawn to healthcare because the data is incredibly valuable—and because many systems are underprepared. A single patient record can be worth more on the black market than a credit card number. At the same time, many hospitals and clinics still rely on legacy systems not designed with today’s threats in mind.
As telehealth, cloud platforms, and connected devices become more common, the risks increase. And because any downtime can put patient safety at risk, healthcare organisations are often under pressure to pay ransoms quickly just to restore operations.
Why healthcare is targeted:
- Valuable data
- Legacy infrastructure
- Expanding digital environments
- High pressure to minimise downtime
Cyber Attacks Across Healthcare Settings
Hospital Cyber Attack
Hospitals run complex networks connecting everything from life-support systems to administrative databases. If attackers breach just one part, they can often move laterally and disrupt entire operations.
These attacks can delay diagnoses, halt procedures, and in worst cases, jeopardise patient care. Entry points often include phishing emails, outdated software, and exposed remote access systems.
GP Data Breach
General practices might seem like small fish, but they hold large volumes of patient data. Limited IT resources and third-party service providers make them easier targets.
When breached, GP surgeries face legal fallout, reputational harm, and disruption to care—not only for their own patients but across wider healthcare networks.
Other High-Risk Healthcare Settings
Healthcare operations increasingly extend beyond traditional clinical walls, and so do cyber threats. Remote workers, third-party vendors, and outpatient centres often connect to core systems but lack the same level of protection. Unsecured home networks and insufficient vendor oversight can all become weak links—allowing attackers to slip in through less obvious pathways.
When these settings are compromised, the impact can ripple across the entire care ecosystem. An exposed third-party billing platform or vulnerable outpatient clinic could grant access to central databases or scheduling systems, causing widespread disruption. As healthcare delivery grows more decentralised, protecting every access point—not just the main hospital network—is vital to maintaining resilience and patient safety.
Common Threats in Healthcare Cybersecurity
Healthcare environments face a range of threat types, many of which stem from low user awareness or poor infrastructure hygiene.
Ransomware: Locks critical systems until a ransom is paid.
Phishing: Tricks staff into handing over credentials or installing malware.
IoMT attacks: Exploits vulnerabilities in internet-connected medical devices.
Third-party risks: Breaches through contractors or service providers.
Insider threats: Employees or contractors who act maliciously or make costly errors.
The Role of Data Protection and Patient Privacy
What Is Data Protection in Health and Social Care?
Protecting health data means more than compliance. It’s about embedding controls like encryption, user permissions, and detailed audit trails into how data is stored and accessed.
Data Security in Healthcare and Patient Trust
Data breaches don’t just harm systems, they erode patient trust and breach strict healthcare data protection guidelines. If patients worry their records aren’t safe, they may avoid sharing vital information. Security builds confidence, which in turn supports better care.
Healthcare IT Trends and their Cybersecurity Challenges
From telemedicine and wearable health devices to cloud-hosted patient records, modern healthcare now depends on a sprawling ecosystem of connected technologies. While these innovations offer better patient outcomes and operational efficiency, they also introduce more entry points for cybercriminals.
Here are some of the most pressing trends shaping healthcare IT.
1. The Growth of Telehealth and Remote Care
While originally accelerated because of the pandemic, the telehealth industry is still expected to grow at a rate of 24% until 2030. Enabling “at-home” doctor’s visits for greater convenience and accessibility, telehealth is a key element of the growing opportunity within healthcare digitalisation.
However, telehealth also presents new cybersecurity challenges as each digital touchpoint expands the attack surface. Each video consultation, patient portal, wearable device, and remote diagnostic tool becomes a potential entry point for threat actors. Not to mention, the ability to manage cyber risks now involves patients’ homes, which can include unsecured networks.
As telehealth expands, healthcare providers must adopt robust identity management, encrypted communication channels, and zero trust access controls to secure remote care environments and maintain patient trust.
2. Cloud Adoption Across Clinical Operations
The healthcare sector is rapidly embracing cloud computing to enhance scalability, data accessibility, and operational efficiency. In 2024, the global healthcare cloud computing market was valued at approximately $54.28 billion and is projected to grow to $197.45 billion by 2032, exhibiting a CAGR of 17.6% during the forecast period.
However, this shift introduces significant data security challenges. Storing sensitive patient data in the cloud increases the risk of data breaches and unauthorised access. Healthcare organisations must implement robust security measures, including data encryption, access controls, and regular security audits, to protect against potential threats.
3. The Rise of AI in Healthcare and Security
Artificial Intelligence (AI) is transforming healthcare by improving diagnostics, personalising treatment plans, and streamlining administrative tasks. By 2025, the global AI in healthcare market is expected to reach $20.9 billion, with projections indicating growth to nearly $150 billion by 2029. AI applications, such as predictive analytics and robot-assisted surgeries, are becoming increasingly prevalent, enhancing patient outcomes and operational efficiency.
Despite its benefits, AI adoption raises cybersecurity concerns. AI systems can be vulnerable to data poisoning, adversarial attacks, and algorithmic biases, potentially compromising patient safety and data integrity. Ensuring the security and reliability of AI systems requires rigorous testing, continuous monitoring, and adherence to ethical standards to mitigate these risks.
