Picture an infusion pump administering medication in a hospital ward while communicating over the hospital network for remote monitoring. Now imagine that the device is running obsolete software containing a known vulnerability, with no recent security update. There may be no flashing warning or obvious system failure. Yet, an attacker could potentially exploit that weakness to disrupt the device, access connected systems or compromise sensitive patient information. This is what makes medical device cybersecurity particularly concerning: the threat can remain hidden until patient care or hospital operations are affected.
Why Medical Devices Are at Risk
Connected medical devices—from infusion pumps and patient monitors to imaging systems, diagnostic equipment and IoT-enabled devices—have expanded the hospital attack surface. Weak authentication, outdated firmware, insecure interfaces, unpatched vulnerabilities and excessive network connectivity can provide attackers with entry points.
The consequences go beyond data theft. Compromising a device can potentially affect confidentiality, integrity and availability, creating risks to clinical operations and, in certain circumstances, patient safety.
Zettawise has witnessed the broader consequences of healthcare cyberattacks. In one of its documented healthcare use cases, ransomware disrupted a hospital's Information System and Radiology operations for more than five days. Zettawise's Incident Response team supported prevention, detection, containment, eradication and recovery. It has also supported a major Indian hospital chain with ISMS and PIMS implementation, VA/PT of ICT infrastructure and workforce training.
What Indian Government Guidelines Apply?
India's medical cybersecurity landscape involves several overlapping requirements and guidance frameworks:
Medical Devices Rules, 2017 (MDR-2017): CDSCO regulates medical devices under the Drugs & Cosmetics Act, 1940 and MDR-2017.
CDSCO Guidance Document on Medical Device Software, 2026: The current guidance addresses medical-device software, including software that can control or influence a device, and defines cybersecurity across the software lifecycle. It references applicable standards and incorporates cybersecurity considerations into regulatory documentation and quality-management processes.
CERT-In Directions, 2022: Covered organisations must report specified cyber incidents to CERT-In within six hours of noticing them and securely maintain ICT logs for 180 days.
ABDM Health Data Management Policy: India's digital-health framework promotes “Security and Privacy by Design” for protecting personal health data.
DPDP Act, 2023 and DPDP Rules, 2025: These establish India's framework for protecting and processing digital personal data, relevant to healthcare organisations handling patient information.
How Zettawise Can Help
Zettawise can help healthcare organisations minimise medical-device cyber risk through IT/OT VAPT, vulnerability assessment, security and regulatory gap analysis, risk-based GRC advisory, incident response, security monitoring and cybersecurity training. Its healthcare-focused experience and specialised IT/OT security capabilities can help organisations identify weaknesses before attackers exploit them and strengthen resilience across connected medical devices, hospital networks and critical information systems.
For modern healthcare, securing medical devices is no longer simply an IT responsibility—it is an essential component of patient safety, operational resilience and cyber risk management.
