Healthcare providers must continue to prioritise patient data security as digital transformation reshapes the industry. Ensuring the security of sensitive information is about more than simply ticking boxes for compliance; it’s about upholding patient trust and safeguarding their wellbeing. In June 2024, the Australian Government announced it would invest $6.4 million towards launching an Information Sharing and Analysis Centre (ISAC) for the Australian healthcare system to contribute to building the sector’s defences.[¹] However, while the government makes a substantial contribution to the sector more broadly, healthcare organisations must take proactive measures within their operations to reinforce cybersecurity without sacrificing continuity of care. 

Healthcare organisations face heightened risks that could lead to devastating breaches of patient data and significant disruptions to care delivery as cyberthreats become increasingly sophisticated and pervasive. The interconnected nature of modern healthcare systems means that a single vulnerability can have far-reaching consequences, affecting the security of sensitive information and the operational integrity of entire networks. The stakes are high, and healthcare providers must adopt a proactive approach to cybersecurity, ensuring that every aspect of their operations is fortified against potential attacks to protect patient data and preserve trust in the healthcare system. 

There are six ways healthcare organisations can achieve this: 

1. Device management: devices range from critical medical equipment to unauthorised wearables and can pose significant risks if not properly monitored. Organisations must proactively identify and monitor all devices connected to their network to better understand their cybersecurity landscape, uncover vulnerabilities, and take pre-emptive actions to mitigate risks. 
2. Cybersecurity assessment: conducting a comprehensive review of existing security measures helps to pinpoint potential risks and areas vulnerable to cyberattacks. Involving security professionals, biomedical staff, and clinical engineering teams delivers a thorough assessment that encompasses both traditional healthcare practices and connected care workflows. 
3. Control implementation: healthcare providers face increasing exposure to security breaches due to growing system interconnectedness. Implementing stringent access controls, such as role-based access, is a key strategy to counter this risk. This approach ensures that only authorised personnel involved in patient care can access medical records, protecting patient data from unauthorised use. 
4. Device segmentation: establishing and enforcing robust network policies ensures proper device communication and bolsters security. Additionally, accurately documenting device details lets organisations detect unusual behaviours and respond swiftly to potential cyberthreats. 
5. Threat response: rapid threat identification and response are vital for safeguarding healthcare environments. A deep understanding of device functions and workflows facilitates quick detection of irregular communication patterns. Timely threat detection and response preserves system integrity and ensures the quality of patient care. 
6. Vulnerability management: managing the vulnerabilities associated with Internet of Medical Things (IoMT) devices is another crucial aspect of healthcare cybersecurity. Developing a clear visibility strategy for these devices lets organisations assess risks accurately and prioritise necessary fixes, reducing exposure to cyberthreats. 

Continually optimising cybersecurity strategies is essential in an evolving threat landscape. Healthcare providers must update their cybersecurity measures regularly and enhance operational resilience to protect connected devices and ensure the ongoing security and integrity of patient data. 

While these steps focus primarily on protecting patient data, they are also critical for ensuring continuity of care. Continuity of care hinges on providing consistent, coordinated services to patients. Safeguarding this continuity requires robust protection against cyberthreats that could interrupt the flow of healthcare. For example, cybersecurity practices such as role-based access, rapid threat response, and continuous strategy optimisation play a vital role in maintaining smooth healthcare delivery and minimising disruptions. Implementing rigorous cybersecurity measures will secure patient data and ensure the seamless delivery of healthcare services. Protecting data and ensuring continuity of care are interconnected, forming a solid foundation for delivering quality healthcare in the digital age.
