According to a 2024 report by HIMSS, over 70% of top-tier hospitals have integrated AI into their threat detection systems.

2. Rise of Ransomware-as-a-Service (RaaS) Targeting Healthcare

The business of breaching hospitals

Ransomware-as-a-Service (RaaS) is one of the fastest-growing cyber threats in 2025. Instead of building their own malware, even low-skilled cybercriminals can now subscribe to prebuilt ransomware toolkits targeting healthcare databases and hospital IT systems.

Healthcare organizations are a prime target because:

• They can’t afford downtime

• They manage highly sensitive data

• Many still lack modern cyber resilience frameworks

Notable statistics:

In Q1 2025 alone, over 38% of ransomware attacks globally targeted the healthcare industry.

Best practices include:

• Regular encrypted backups

• Network segmentation

• Cyber insurance policies

3. Zero Trust Architecture Adoption

Trust no one, verify everything

Traditional perimeter-based security models are no longer effective against today’s sophisticated threats. Enter Zero Trust Architecture (ZTA)—a model that assumes no user, device, or application is inherently trustworthy.

Key elements of Zero Trust in healthcare:

• Role-based access controls (RBAC)

• Micro-segmentation of networks

• Continuous verification using identity and access management (IAM)

Why healthcare is adopting ZTA:

• To protect against insider threats

• To secure remote access for telehealth professionals

• To comply with new regulations demanding fine-grained access control

Implementing ZTA ensures that even if one device or account is compromised, the damage is contained and traceable.

4. Securing Internet of Medical Things (IoMT) Devices

The hidden cybersecurity risk in medical equipment

From insulin pumps and pacemakers to connected MRI machines, Internet of Medical Things (IoMT) devices are essential—but dangerously vulnerable.

In 2025, attackers are increasingly using unpatched IoMT endpoints as entry points into broader hospital networks.

Challenges in IoMT security:

• Limited device memory restricts security patching

• Devices often run outdated firmware

• Lack of security standards across vendors

Best practices for IoMT security:

• Network isolation of IoMT devices

• Firmware updates via secure pipelines

• Device usage logs for anomaly detection

Stat: The FDA now mandates cybersecurity certifications for all new IoMT devices submitted for approval in 2025.

5. Cloud Security Enhancement for Healthcare Data

Migrating safely to the cloud

The shift to cloud-based storage for healthcare data has accelerated, but so have the threats. Storing electronic health records (EHRs) on the cloud offers scalability, but exposes sensitive data to risks like misconfigured S3 buckets and account hijacking.

Cloud security strategies:

• Use HIPAA-compliant cloud services

• Enable encryption at rest and in transit

• Apply identity federation and Zero Trust to cloud access

Leading providers like AWS HealthLake, Google Cloud Healthcare, and Azure for Health are offering cloud-native security solutions tailored for healthcare.
