European cybersecurity agencies have warned that with the gradual application of IoT technology, the risk of hospital attacks is also exponential.
Ransomware and denial of service attacks are just the tip of the iceberg: hospitals are about to become the next big target for cyberattacks, and the introduction of Internet of Things (IoT) devices will make medical systems more vulnerable.
Networked medical devices can provide more protection for patient safety and improve efficiency. The advantages are especially obvious when connecting with clinical information systems. However, the European Technical Security Agency Enisa warned that these technologies have also brought certain risk.
The hospital will become the next target of cyber attacks
In order to better serve and even care for patients remotely, the hospital has gradually turned to various smart solutions, sometimes ignoring these emerging security issues.
Enisa warned that the hospital will be the next target for cyber attacks.
With the introduction of these connected devices, the possibility of hospital attacks is also growing exponentially. Healthcare organizations should identify the security requirements for various IoT components and determine how they relate to each other or to the Internet. According to the report, equipment manufacturers should consider the hospital from the perspective of designing systems and services.
Udo Helmbrecht, executive director of ENISA, said that when devices are connected to each other, people make decisions that allow devices to provide automated services that increase the efficiency of the hospital, but at the same time, devices can be affected by malicious instructions.
Problems with the application of the Internet of Things in medical systems
One of the problems is that the hospital contains all kinds of data that hackers want. For offenders, personal health information is more valuable than financial information, and after breaking into the hospital system, they are exposed to a variety of prescription drugs.
People have become increasingly dependent on IoT devices. We rely too much on networking technologies, but we don't have enough power to keep it safe. We need a higher standard of care, especially for some patients, these medical devices are critical.
Unfortunately, IoT companies often don't think that security needs to be prioritized. They all think that this trouble can be solved later. But the current problem is that these systems can now save both the lives of patients and kill them.
In the realization of the Internet of Things solution, because of the low cost and specific functions of medical IoT devices, people choose to use them, but the value of neglected security costs is even higher than the cost of the components themselves. Vulnerabilities that are common in medical IoT devices are not only attacked by malicious instructions, but can also cause system failures and threaten human life.
Issues to be aware of when using medical IoT devices include:
Communication between the smart device and the reservation system may leave an opportunity for malicious attackers to gain unauthorized access to the system and data. The introduction of new components provides an opportunity for new attacks.
IoT devices are scattered throughout the hospital, their physical security is difficult to guarantee, the risk of being stolen or destroyed is high, and more protection is needed.
Because the construction of medical devices is based on the intended use, the designer does not consider the risk of device abuse. This can also lead to a large number of system vulnerabilities in the entire medical system.
After large-scale use of IoT devices, hospitals will attract hackers to explore viable attack paths. Therefore, device manufacturers and security companies need to address all vulnerabilities.
Device life is another problem: when a hospital gets an IoT device, it may be out of date. Because according to EU legislation, medical devices such as MRI machines take nearly three years from design to testing to production, which means that these devices are considered antiques before installation, and IoT components are built in this way. Above the device.
postscript
IoT devices run embedded operating systems and applications without any malware detection and the ability to prevent intrusions. These devices are small, have limited processing power, and are often unable to encrypt or take other effective security measures. Reconfiguring or upgrading devices is almost impossible.
When a device has security issues, it is often impossible to alert users in a clear way, which means that an IoT security vulnerability will not be discovered and corrected even if it exists for a long time.
It has been proven that stolen medical devices will act as bridgeheads, allowing malware to spread further in hospitals. This is especially important in the healthcare sector because in traditional security mechanisms, devices can be denied access by auto-shutdown, which is more secure than IoT devices that are automatically turned on when a failure occurs.
