What cybersecurity domains are critical for healthcare organizations?

TL;DR: Healthcare organizations rely on cybersecurity domains like asset security, IAM, and security operations to protect patient data, ensure clinical continuity, and comply with regulations such as HIPAA, GDPR, and ISO 27799.

The 6clicks expert guide Mastering the Cybersecurity Domain in 2025 underscores that healthcare organizations face unique cyber challenges due to the high sensitivity of medical data, reliance on connected devices, and the life-critical nature of clinical services.

Hospitals, telehealth providers, and pharmaceutical companies use the cybersecurity domains to secure electronic health records (EHRs), manage third-party risks, and prevent ransomware attacks that could compromise care delivery.

Most critical domains for healthcare:

• Asset security
  Ensures the confidentiality, integrity, and availability of protected health information (PHI), aligning with regulations like HIPAA and ISO 27799.

• Identity and access management (IAM)
  Restricts access to patient records, devices, and apps based on clinical role and time-limited sessions.

• Security and risk management
  Implements policies, training, and governance structures to align with risk tolerance and data protection laws.

• Security operations
  Enables early detection and response to threats targeting patient systems, connected devices, and admin networks.

• Security assessment and testing
  Validates that systems, third-party vendors, and IoT medical devices are secure and properly configured.

Why domains matter in healthcare

Cybersecurity lapses in healthcare lead to:

• Compromised patient safety

• Service outages in hospitals and labs

• Data loss affecting diagnoses and treatments

• Regulatory fines and legal action (e.g., HIPAA violations)

In 2025, threat actors increasingly target healthcare systems due to aging infrastructure and urgent service delivery—making domain-driven cybersecurity a public health priority.
