Specific Medical Device IoT Security Threats

The widespread use of IoT in healthcare comes with a specific set of threats, the most common of which must be addressed. Let’s examine the medical device IoT security risks.

Medical Device IoT Security Threats

Unauthorized Access

Unauthorized access is one of the most common security issues with IoT devices in healthcare. Unfortunately, a lot of devices don’t have proper security features and come with default passwords, making them vulnerable to hacker attacks. These devices also don’t have two-factor authentication features, which is a must for all industries, not only healthcare.

Malware and Ransomware Attacks

Since the Internet of Things devices are interconnected, an attack on one link can spread through the entire system. That is why each link should be secured appropriately. Malicious software can infiltrate the Internet of Things devices, compromising their functionality and exposing sensitive patient data to unauthorized parties. Ransomware attacks, in particular, can encrypt medical records and demand ransom payments, disrupting healthcare operations and compromising patient care.

Man-in-the-Middle (MitM) Attacks

Man-in-the-Middle (MitM) attacks occur when an unauthorized third party intercepts communication between the Internet of Things devices and their intended recipients. By exploiting vulnerabilities in network protocols or device configurations, attackers can eavesdrop on sensitive data exchanges, manipulate information, or inject malicious content into communication streams, compromising the integrity and confidentiality of patient information.

Distributed Denial of Service (DDoS) Attacks

Last but not least, among the security and privacy issues with IoT in healthcare are distributed denial of service (DDoS) attacks. They pose a significant threat to healthcare IoT infrastructure by overwhelming network resources and disrupting service availability. Attackers can exploit vulnerabilities in the Internet of Things devices to enlist them in botnets, orchestrating coordinated attacks aimed at flooding healthcare networks with malicious traffic. These attacks can impair critical healthcare services, causing disruptions in patient care delivery and compromising the integrity of medical systems.

Ways Hospitals Can Help Improve Their IoT Security

At least 75% of healthcare organizations have one vulnerability or security alert. Besides challenging security issues, IoT systems don’t always comply with the security requirements of laws such as HIPAA. However, some strategies can help hospitals address these problems and improve their IoT healthcare security; let’s explore them.

Ways Hospitals Can Help Improve Their IoT Security

Maintaining Vigilant Visibility

The first step hospitals and healthcare organizations should take is to establish complete visibility of all elements of the IoT network. That’s the task of biomed and infosec teams; they need a complete picture of the assets used in the hospital’s network and how they are connected with each other. When they know about the number of devices and their connection, it’s time to focus on the key applications and components that are underneath the OS. These applications usually include EHRs, picture archiving, and communication systems (PACS).

Identifying Device Exposures

There are two main types of vulnerabilities devices are prone to; static and dynamic. Static exposures, consisting of Common Vulnerabilities and Exposures, can be addressed independently. Dynamic exposures, on the other hand, are more challenging to identify and address. However, it is possible to use AI and automation to identify vulnerabilities and tackle them swiftly.

Implementing a Zero-Trust Approach

After identifying all the assets and their vulnerabilities, it’s time to implement a ZT approach to address any challenges to healthcare IoT security. This approach proposes limiting access to vulnerable devices and apps, only allowing certain professionals to access them. The devices are placed into different segments based on their vulnerability levels, so it becomes easier to manage accesses, requirements, and security controls.

Rolling Out Virtual Patching for Legacy Systems

A lot of medical devices run on legacy software and systems, and some hospitals may not be able to upgrade or patch those systems, leading to more security issues. Investing in ZT approach allows hospitals to use other forms of protection, such as virtual patching in case if it’s impossible to take the device offline for patching.

Establishing Transparency Across the Ecosystem

One of the main approaches for preventing threats and IoT security healthcare issues is establishing a high level of transparency and communication in the organization. When hospitals buy devices, they need to involve their security teams because they know best how to keep the devices safe over time. Hospitals, security teams, device sellers, and manufacturers must work together. They need to develop plans and ideas to make sure that security is a big priority for medical devices.

Aligning protection practices with regulatory requirements upholds trust and maintains healthcare IoT ecosystems' integrity while protecting patient data and privacy.

What are the three types of IoT protection?

In the realm of IoT protection, three essential pillars emerge as key components:Device Security: Central to IoT protection is safeguarding the devices themselves from potential threats. This involves integrating various security features directly into the devices. Authentication mechanisms serve as the initial defense, validating the identity of users or devices attempting access. Robust encryption methods protect data stored on IoT devices, shielding it from unauthorized access or interception. Additionally, secure boot processes ensure the integrity of device software, preventing unauthorized modifications during startup.Network Security: The protection of communication channels and infrastructure used by IoT devices is of utmost importance. Network segmentation divides IoT devices into separate network segments, isolating them from critical systems and reducing the risk of unauthorized access. Firewalls act as vigilant guards, monitoring and controlling incoming and outgoing network traffic to allow only authorized communication while blocking potential threats. Intrusion Detection Systems (IDS) continually monitor network traffic for signs of suspicious activity, promptly alerting to potential threats and facilitating rapid response.Data Security: Preserving the confidentiality, integrity, and availability of data transmitted by IoT devices is essential. Data encryption ensures data remains indecipherable to unauthorized entities both in transit and at rest. Access controls enforce stringent authorization measures, ensuring only authorized users or devices can access sensitive data. Data integrity checks verify the integrity of data, ensuring it remains unaltered during transmission or storage.By strengthening these three pillars—device protection, network protection, and data protection—organizations can construct a robust framework to mitigate risks and safeguard their IoT ecosystems against a multitude of potential threats.
