Huawei Data Storage Provides Cutting-Edge Ransomware Protection for Kyoto Min-iren Chuo Hospital

In recent years, with the digital transformation of medical information such as electronic medical records (EMR), PACS medical images, and lab data, ensuring healthcare data resilience while maintaining business continuity has become a critical challenge in hospital operations.

Challenges

In the healthcare sector, organizations face exceptionally strict requirements for data management.

• Zero tolerance for data loss: Because medical data is directly tied to diagnosis, treatment, and emergency care, any tampering or loss is strictly unacceptable.

• Effective handling of evolving threats: As ransomware grows more sophisticated and stays dormant for longer, traditional backup solutions can no longer provide an effective defense.

• Resilient continuity: Systems must be capable of rapid recovery against an attack to ensure that medical services remain uninterrupted.

• Backup integrity: There is a pressing need to prevent backup data itself from becoming a primary target of attacks.

Confronted with these challenges, Kyoto Min-iren Chuo Hospital required a next-generation data protection platform equipped with immutability, air gapping, and proactive detection.

Ransomware Protection Storage Solution

To meet the high reliability requirements of the healthcare sector, Huawei Data Storage offers an integrated offline backup platform powered by OceanProtect. This platform builds a comprehensive ransomware protection solution on three pillars:

Secure snapshots: By applying the Write Once, Read Many (WORM) technique at the storage layer, the solution creates immutable snapshots of critical medical data to prevent tampering. This greatly reduces the risk of unauthorized encryption by ransomware.

Physical air gapping: Backup data is stored in an isolated zone, physically severed from the production environment. Only the minimal necessary communication ports are opened during backups and remain completely disconnected at all other times, effectively eliminating the attack path.

Ransomware detection and analysis with HyperDetect: Leveraging machine learning algorithms, the system analyzes data change patterns to identify ransomware-related anomalies. This helps determine the scope of impact and make informed recovery decisions.

Solution Benefits

By deploying Huawei's data storage solution, Kyoto Min-iren Chuo Hospital has achieved the following results:

• Strengthened the tamper-resistance and overall resilience of medical data.

• Reduced the potential risk of ransomware attacks through backup data isolation.

• Enhanced visibility into cybersecurity incidents and improved emergency response capabilities.

• Established a resilient data protection platform that ensures continuity of healthcare services.

In doing so, the hospital has successfully built a reliable environment that supports the streamlined digital transformation of healthcare.

Future Outlook

Looking ahead, Huawei will continue to deepen its collaboration with healthcare institutions, using data storage and resilience technologies to build a solid digital foundation for public well-being.

To address potential concerns over rising virtualization software costs, the hospital also plans to evaluate Huawei's DCS solution. The goal is to create a more flexible and cost-effective virtualization environment. Huawei remains committed to providing the critical technologies needed at the healthcare frontline, safeguarding a resilient and sustainable journey of digital healthcare.
