MRI, or Magnetic Resonance Imaging, is a medical imaging modality that creates detailed internal body scans using magnetic fields and radio waves. In hospitals, an MRI scanner is rarely isolated: it often exchanges orders, images, and reports with PACS, RIS, and other clinical systems.
That connectivity makes MRI relevant to cyber security. Attackers may target the scanner directly, but they can also abuse nearby systems, remote access, or vendor maintenance paths to disrupt imaging, alter data, or delay care. The biggest risk is often not theft but integrity and availability: a corrupted image or an unavailable scanner can affect diagnosis, treatment planning, and patient safety. Defenders protect MRI environments with network segmentation, strong authentication, logging, patching, and tight control over third-party access so the imaging workflow stays reliable and trustworthy.
