Introduction

Healthcare organisations handle sensitive patient information and often rely on connected devices, booking systems, email, cloud platforms and third-party suppliers. Cyber security failures can affect confidentiality, patient trust and service availability.

The healthcare environment brings unique challenges, including a mix of clinical systems, administrative applications and medical devices. A practical, risk-based approach helps organisations reduce risk while continuing to deliver safe and effective care.

Ransomware is an availability risk

Healthcare services cannot always tolerate long outages. Ransomware or malware can disrupt access to clinical systems, affect appointment booking and create operational pressure across teams.

Tested backups, endpoint detection, patching, restricted admin rights and clear downtime procedures help reduce disruption if ransomware or malware appears.

Protect patient data

Patient data is highly sensitive and must be protected from unauthorised access, loss and inappropriate sharing. Data exposure may happen through misconfiguration as well as direct attack.

Apply least privilege, strong authentication, encryption, secure sharing processes and regular access reviews. Monitor cloud storage, email attachments and third-party access to reduce the risk of accidental or deliberate data exposure.

Supplier and device risk

Healthcare providers rely on IT providers, software vendors and device suppliers. Remote access can be necessary for support, but it needs to be controlled and monitored.

Review who can access systems, how access is logged and how quickly it can be revoked. Consider the security of connected medical devices, network segmentation and the management of third-party accounts.
