Healthcare Information Security: Australian Privacy Requirements – Blogs Christian Sajere Cybersecurity and IT Infrastructure

Australia’s healthcare sector faces an unprecedented cybersecurity crisis. According to the Australian Cyber Security Centre (ACSC) Annual Cyber Threat Report 2023–24¹, published by the Australian Signals Directorate (ASD), 41% of healthcare organisations reported experiencing a cyber attack in 2023, highlighting the sector’s vulnerability to increasingly sophisticated threat actors. These attacks include tactics such as ransomware, phishing, and system intrusions targeting hospitals, clinics, insurers, and e-prescription providers.

In the first half of 2024 alone, the Office of the Australian Information Commissioner (OAIC)’s “Notifiable Data Breaches Report: January to June 2024”² recorded 102 notifiable data breaches from the healthcare sector — the highest of any industry during that period. This figure is based on mandatory disclosures under the Notifiable Data Breaches (NDB) scheme and reflects confirmed incidents where personal information was accessed or disclosed in a way likely to cause serious harm.

While the “cyber attack” rate reported by the ACSC includes both successful and attempted intrusions, the OAIC’s “notifiable data breaches” refer strictly to verified events that met the legal threshold for reporting.

This surge in incidents underscores the urgent need for stronger cyber risk management. The ACSC recommends that healthcare providers adopt the Essential Eight³ mitigation strategies as a baseline for improving their cyber resilience.

As the digital transformation of healthcare accelerates, the intersection of cybersecurity and privacy compliance has become critical for protecting patient information and maintaining operational integrity.

The Australian healthcare industry operates under a complex regulatory framework that includes the Privacy Act 1988⁴, the Australian Privacy Principles (APPs), and sector-specific guidelines from the Australian Signals Directorate (ASD). With Australian’s health information being even more attractive to cyber criminals than their financial details, healthcare providers must implement robust security measures while ensuring compliance with privacy requirements.

The Current Threat Landscape

Escalating Cyber Threats

The healthcare sector has emerged as a primary target for cybercriminals globally. 88 million individuals were affected by large breaches, compromising vast amounts of electronic protected health information (ePHI) last year according to IBM’s analysis in “Cybersecurity risks in healthcare are an ongoing crisis.”⁵ The situation in Australia mirrors this global trend, with 32% of healthcare cyber incidents involving compromised accounts or credentials according to ASD’s Annual Cyber Threat Report 2023-2024⁶.

The Australian Signals Directorate’s threat intelligence in Annual Cyber Threat Report 2023-2024⁷ reveals that 71% of extortion-related incidents involved ransomware, demonstrating the evolving sophistication of attacks targeting healthcare infrastructure. These attacks not only compromise patient data but also disrupt critical healthcare services, potentially endangering lives.

Medical Device Vulnerabilities

Modern healthcare relies heavily on interconnected medical devices, creating new attack vectors. The average number of connected medical devices per hospital bed is approximately 10 to 15, according to IBM’s research in “Medical devices are vital, but vulnerable.”⁸ This proliferation of connected devices has expanded the attack surface significantly, with many devices manufactured without secure-by-design principles.

The challenge is compounded by legacy systems that were not designed with cybersecurity in mind. Many older medical devices run outdated software and lack robust security protocols, making them vulnerable entry points for attackers seeking to penetrate healthcare networks.

Australian Privacy Regulatory Framework

Privacy Act 1988 and Recent Updates

The Privacy Act 1988 forms the cornerstone of Australia’s privacy protection framework. 2024 was a year of significant developments in the Australian privacy law landscape, with updates to the Privacy Act 1988 resulting from the Privacy and Other Legislation Amendment. These amendments have strengthened privacy protections and introduced new compliance requirements for healthcare organizations.

The Australian Privacy Principles (APPs) establish specific obligations for the collection, use, disclosure, and storage of personal information. APP 3.5 states that the collection of personal data must only be by fair and lawful means, requiring healthcare providers to implement transparent and ethical data collection practices.

Sector-Specific Requirements

Healthcare organizations must navigate additional regulatory requirements beyond the general privacy framework. Apart from general obligations, there are no mandated IT security standards for the handling of health data in Australia, though specific standards have been developed, including the Information security management in health using ISO/IEC 27002.

The Australian Digital Health Agency emphasises that healthcare professionals must stay informed and prepared for cyber threats targeting digital health assets, providing sector‑specific guidance, training, alerts, and international best practice collaboration to support this goal.

Australian Signals Directorate Guidelines

The ASD’s Australian Cyber Security Centre (ACSC) plays a crucial role in healthcare cybersecurity. ASD’s ACSC leads the Australian Government’s efforts on cyber security, bringing together capabilities to improve the cyber resilience of the Australian community. The organization provides comprehensive guidance through its Information Security Manual⁹ and Essential Eight¹⁰ framework.

The Information Security Manual, released in December 2024, serves as a cybersecurity framework for CISOs, CIOs and other cybersecurity leaders to protect information technology and operational technology systems, applications and data.

Key Compliance Challenges

Data Breach Notification Requirements

Under the Notifiable Data Breaches (NDB) scheme, healthcare organizations must report eligible data breaches to the Office of the Australian Information Commissioner (OAIC) within 72 hours. The high volume of breaches in 2024 demonstrates the ongoing challenges in maintaining data security while ensuring timely compliance with notification requirements.

Healthcare providers must establish robust incident response procedures that balance the need for thorough investigation with regulatory reporting timelines. This includes implementing automated detection systems and predefined escalation procedures to ensure rapid response to potential breaches.

Cross-Border Data Transfers

Many healthcare organizations utilize cloud services and third-party providers that may involve cross-border data transfers. The Privacy Act includes specific requirements for overseas disclosure of personal information, requiring organizations to ensure adequate protection of personal information when transferred internationally.

Healthcare providers must conduct thorough due diligence on international service providers and implement appropriate safeguards to protect patient information during cross-border transfers.

Consent Management

The healthcare sector faces unique challenges in obtaining and managing patient consent for data processing. The Privacy Act requires clear, informed consent for the collection and use of personal information, but healthcare settings often involve emergency situations where obtaining consent may be impractical.

Healthcare organizations must develop sophisticated consent management frameworks that balance regulatory requirements with practical healthcare delivery needs.

Technology Solutions and Best Practices

Artificial Intelligence and Machine Learning

Healthcare organizations are increasingly leveraging AI and machine learning to enhance both cybersecurity and privacy compliance. Healthcare providers can enhance medical device security, strengthen their cybersecurity posture and improve the quality of patient care by leveraging generative artificial intelligence.

Key AI applications include:

Threat Intelligence: AI systems can analyze vast amounts of data to detect and respond to potential threats, providing real-time alerts to healthcare providers about emerging risks.

Compliance Monitoring: Automated systems can ensure adherence to privacy regulations by continuously monitoring data handling practices and identifying potential compliance gaps.

Incident Response: AI-driven analysis can identify patterns in potential attacks, providing insights to analysts for improved decision-making and reducing response times.

Zero Trust Architecture

Implementing a zero trust security model is becoming essential for healthcare organizations. This approach assumes that no user or device should be trusted by default, regardless of their location within the network perimeter.

Healthcare providers should implement multi-factor authentication, network segmentation, and continuous monitoring to create a robust security posture that protects patient information while maintaining operational efficiency.

Encryption and Data Protection

Healthcare organizations must implement comprehensive encryption strategies covering data at rest, in transit, and in use. This includes:

End-to-end encryption for patient communications
Database encryption for electronic health records
Secure communication protocols for medical device connectivity
Regular encryption key management and rotation

Emerging Trends and Future Considerations

Regulatory Evolution

The prospect of the Tranche 2 reforms to the Privacy Act and the enactment of the Scams Prevention Framework on 21 February 2025 make this a space to watch closely. Healthcare organizations must prepare for evolving regulatory requirements and ensure their compliance frameworks are adaptable to future changes.

Digital Health Transformation

The continued digitization of healthcare services presents both opportunities and challenges. Telehealth, remote monitoring, and AI-powered diagnostics are transforming patient care delivery but also expanding the attack surface for cybercriminals.

Healthcare providers must balance innovation with security, ensuring that new technologies are implemented with appropriate privacy and security safeguards from the outset.

Supply Chain Security

Healthcare organizations increasingly rely on complex supply chains involving multiple vendors and service providers. Healthcare providers often have limited end-to-end visibility across their medical device network and supply chain, which limits proper detection and response.

Implementing comprehensive supply chain security assessments and ongoing monitoring is essential for maintaining overall security posture.
