FREMONT, CA: Internet of Medical Things (IoMT) gadgets have transformed the healthcare business, driving down costs while also improving patient care and comfort. However, because of their extensive use in hospitals, they can be a lucrative target for hackers, exposing vulnerabilities and posing security issues.
Several critical efforts should be taken by healthcare institutions to tighten and enforce security for the numerous devices that keep their operations running.
Steps toward IoMT Device Security
- Healthcare organizations should Implement segmentation controls and improve network cleanliness. This entails segmenting the network into multiple zones or subnetworks, each with its own set of security policies based on the devices and users. For example, to prevent NAME: WRECK, security experts propose isolating crucial vulnerable devices from the rest of the network by segmenting them. Some businesses separate their IoT networks from their IT networks entirely.
- One should maintain awareness of known and released patches, particularly for highly vulnerable devices. Patch application should be prioritized and scheduled by organizations in order to optimize the effect while minimizing the harm. Organizations should disconnect devices from the network when they are unable to patch. Examine for insecure or out-of-date software and firmware. If updates are available, ensure that the patching procedures are safe.
- One should increase the security of the passwords on their device. All too often, healthcare organizations bring IoMT devices online without changing the factory-default users and passwords, which can have disastrous consequences. Strong passwords or passphrases should be required, and two-factor authentication should be considered for the most important devices. Organizations should only allow devices to see and access information that is required for them to accomplish their tasks.
