With the explosion of growth in technology and its influence on our lives, we have become increasingly dependent on it. The medical field is no exception: Medical professionals trust technology to provide them with accurate information and base life-changing decisions on this data. McAfee’s Advanced Threat Research team is exploring these devices to increase awareness about their security.
Some medical devices, such as pacemakers and insulin pumps, have already been examined for security concerns. To help select an appropriate target for our research, we spoke with a doctor. In our conversations we learned just how important the accuracy of a patient’s vital signs is to medical professionals. “Vital signs are integral to clinical decision making” explained Dr. Shaun Nordeck. Bedside patient monitors and related systems are key components that provide medical professionals with the vital signs they need to make decisions; these systems are now the focal point of this research.
Most patient monitoring systems comprise at minimum of two basic components: a bedside monitor and a central monitoring station. These devices are wired or wirelessly networked over TCP/IP. The central monitoring station collects vitals from multiple bedside monitors so that a single medical professional can observe multiple patients.
