Introduction

Healthcare organisations are increasingly adopting connected technologies to improve patient monitoring, diagnostics, clinical workflows, remote care, and operational efficiency. Connected medical devices, wearable sensors, imaging systems, laboratory equipment, patient-monitoring technologies, smart clinical equipment, mobile applications, cloud platforms, and healthcare networks can now operate as part of a single digital ecosystem.

This connectivity also creates additional cybersecurity exposure.

A connected healthcare device may communicate with hospital networks, cloud applications, APIs, vendor platforms, databases, or other medical devices. If one component contains a security weakness, it may create an opportunity for unauthorised access, data exposure, or movement towards other connected systems.

The Swiss National Cyber Security Centre (NCSC) recommends measures such as network segmentation, restricting unnecessary internet access, using secure communication protocols, eliminating default credentials, and implementing stronger authentication for IoT devices. 

For healthcare environments, the consequences of a compromised connected device can extend beyond conventional IT security concerns. Availability, patient safety, clinical operations, sensitive information, and regulatory obligations may all need to be considered.

Cyberintelsys Connected Healthcare IoT Device Security Assessment provides a structured way to identify weaknesses across medical IoT devices and the infrastructure supporting them.

Importance of Connected Healthcare IoT Security Assessment

Connected healthcare environments can contain devices with different operating systems, firmware versions, communication protocols, authentication mechanisms, and vendor dependencies.

A security assessment helps organisations understand how these components interact and where weaknesses may exist.

1. Identify Vulnerable Healthcare Devices

Connected devices may expose services or interfaces that were not designed with today’s threat landscape in mind.

Assessment can cover technologies such as:

• Patient monitoring devices

• Connected diagnostic equipment

• Medical imaging systems

• Smart clinical equipment

• Laboratory devices

• Remote patient-monitoring systems

• Healthcare sensors

• Wearable medical technologies

• Connected treatment-support equipment

2. Identify Unauthorised Access Risks

Default credentials, weak passwords, exposed administrative interfaces, excessive permissions, and inadequate authentication can increase the risk of unauthorised access.

Security testing can determine whether these controls are appropriately implemented.

3. Protect Healthcare Networks

A connected device should not automatically have unrestricted access to the wider healthcare network.

Assessment can examine whether appropriate segmentation exists between:

• Medical devices

• Clinical systems

• Administrative infrastructure

• IoT gateways

• Guest networks

• Cloud services

• Vendor environments

4. Assess Data Security

Connected healthcare devices may collect or transmit sensitive information through APIs, applications, wireless networks, or cloud platforms.

Security assessment can identify weaknesses involving:

• Data transmission

• Encryption

• Authentication

• Authorisation

• API access

• Storage

• Session management

5. Detect Outdated Components

Medical devices may have long operational lifecycles, and software updates can sometimes involve additional operational or regulatory considerations.

A security assessment can help identify vulnerable software, firmware, services, and components requiring remediation, compensating controls, or closer monitoring.

Our Methodology

A connected healthcare environment requires a controlled assessment methodology that considers both cybersecurity risks and the operational sensitivity of medical technology.

1. Asset Discovery and Scope Definition

The first stage establishes the devices and infrastructure included within the assessment.

This can include:

• Medical IoT devices

• Device gateways

• Network infrastructure

• Web applications

• Mobile applications

• APIs

• Cloud services

• Wireless interfaces

• Remote-access infrastructure

The objective is to establish an accurate view of the connected environment.

2. Architecture and Attack-Surface Assessment

Communication paths between devices, applications, networks, cloud services, and third-party platforms are examined.

This helps identify:

• Internet-facing interfaces

• Unnecessary services

• Exposed ports

• Remote-management interfaces

• Device-to-device communication

• External dependencies

• Potential attack paths

3. Vulnerability Identification

Technical testing is performed to identify vulnerabilities across the authorised environment.

Depending on scope, this may include assessment of:

• Firmware

• Operating systems

• Network services

• Device configurations

• Authentication mechanisms

• APIs

• Applications

• Wireless interfaces

• Communication protocols

4. Security Configuration Review

Device and network configurations can be reviewed for weaknesses such as unnecessary services, insecure protocols, weak credentials, excessive privileges, and insufficient access restrictions.

The NCSC recommends secure protocols such as SSH and HTTPS rather than cleartext protocols such as Telnet and HTTP for applicable IoT environments. 

5. Controlled Penetration Testing

Where authorised, selected vulnerabilities can be safely validated through controlled penetration testing.

Testing may include:

• Authentication testing

• Authorisation testing

• Network-service testing

• API testing

• Application testing

• Remote-access testing

• Wireless security testing

• Segmentation testing

Testing is performed according to defined rules of engagement and the operational requirements of the healthcare environment.

6. Risk Analysis

Identified vulnerabilities are evaluated based on factors such as exposure, exploitability, affected assets, potential impact, and the role of the affected component within the healthcare environment.

This provides organisations with a clearer basis for prioritising remediation.

7. Reporting and Remediation Guidance

The final report can document the identified vulnerabilities, affected assets, technical evidence, risk context, and recommended remediation measures.

Where required, findings can subsequently be retested to validate remediation.

Connected Healthcare IoT Security Assessment Services

Cyberintelsys can support healthcare organisations and medical-technology environments through different layers of IoT security assessment.

1. Healthcare IoT Vulnerability Assessment

A structured assessment identifies known and configuration-based vulnerabilities across connected medical devices and supporting infrastructure.

It can include:

• Vulnerability scanning

• Configuration review

• Service identification

• Software and firmware assessment

• Authentication review

• Network exposure analysis

2. Medical Device Security Assessment

Connected medical devices can be assessed for weaknesses affecting device interfaces, services, firmware, authentication, configurations, and communications.

The assessment approach can be adapted to the operational characteristics of the device.

3. IoT Network Security Assessment

Network architecture can be examined to determine whether connected devices are appropriately isolated and whether unnecessary communication paths exist.

Areas can include:

• Network segmentation

• Firewall controls

• Access-control rules

• Device-to-network communication

• External connectivity

• Lateral-movement paths

4. API and Application Security Assessment

Healthcare IoT ecosystems frequently rely on APIs and applications to transfer information between devices and backend systems.

Testing can assess:

• Authentication

• Authorisation

• API access controls

• Input validation

• Session management

• Data exposure

• Application configuration

• Secure communication

5. Firmware Security Assessment

Where technically and contractually appropriate, firmware can be examined for vulnerabilities such as insecure configurations, outdated components, embedded credentials, exposed services, and other security weaknesses.

6. Wireless Security Assessment

For devices using wireless connectivity, relevant interfaces can be assessed for weaknesses involving authentication, encryption, access controls, and communication security.

7. Penetration Testing

Controlled penetration testing can validate whether identified weaknesses are practically exploitable within the approved scope.

8. Remediation and Retesting

After vulnerabilities have been addressed, retesting can help verify whether corrective measures have successfully reduced or removed the identified security weaknesses.
