Network Segmentation Key to Mitigating Ransomware Risk for Hospitals

When it comes to ransomware in healthcare, one key to survival is really just like any other infection: it’s all about quarantine.
Ransomware attacks this year have increased 300 percent compared to 2015, with hospitals becoming the most lucrative target. Healthcare organizations, typically behind the cybersecurity curve, must respond to the evolving threat or face dangerous consequences. But how?
In the Cybersecurity Law Report, Shahryar Shaghaghi, Technology Advisory Services National Leader and Head of International BDO Cybersecurity, identifies two key steps that hospitals should take to protect against ransomware:
  1. Identify system vulnerabilities. Whether you hire an outside organization to help with this or not, you should put an effective attack response plan in place, and continuously evaluate and enhance that plan as risks evolve.
  2. Conduct network segmentation. Much like quarantining ill patients, when a ransomware attack does occur, you should isolate that part of your network so the attack cannot spread. If you have already assigned a secondary hospital, this allows you to transfer relevant data quickly.
