Introduction

Modern hospitals in Switzerland increasingly depend on connected technologies to support patient care, clinical operations, diagnostics, monitoring, and administrative processes. Medical devices, patient monitoring systems, smart infusion pumps, imaging equipment, connected laboratory systems, building-management systems, access-control devices, and other Internet of Things (IoT) technologies can communicate across hospital networks and, in some cases, with cloud platforms or external services.

This connectivity can improve efficiency and enable healthcare professionals to access information quickly. At the same time, every connected device can introduce another potential attack surface. A vulnerable IoT device may expose sensitive information, provide an entry point into hospital networks, or affect the availability of systems that support clinical operations.

For hospitals, cybersecurity therefore extends beyond conventional servers, laptops, and applications. A comprehensive security assessment should consider the relationship between IoT devices, medical technology, network infrastructure, applications, identities, and sensitive healthcare information.

Cyberintelsys Hospital IoT Security Audit combined with Vulnerability Assessment and Penetration Testing (VAPT) can help identify security weaknesses before they are exploited and provide a structured basis for remediation.

Why Is a Hospital IoT Security Assessment Important?

Hospital IoT environments can be significantly different from conventional corporate IT environments. Many connected medical devices have long operational lifecycles, specialised software, vendor-controlled configurations, or availability requirements that make traditional security controls difficult to apply.

An assessment helps organisations understand where security weaknesses exist and how they could affect the wider environment.

1. Identify vulnerable connected devices

An assessment can identify outdated firmware, insecure configurations, weak authentication mechanisms, unnecessary services, exposed interfaces, and other weaknesses across connected devices.

2. Reduce unauthorised access risks

Default credentials, excessive privileges, poorly secured remote access, and weak authentication can create opportunities for unauthorised users to access devices or connected systems.

3. Protect sensitive healthcare information

IoT environments can interact with electronic health records, patient-monitoring platforms, laboratory systems, imaging systems, and other applications containing sensitive information. Security testing helps identify pathways through which such information could potentially be exposed.

4. Strengthen network segmentation

Swiss NCSC guidance for IoT recommends appropriate protection such as changing default credentials, limiting internet exposure, and separating IoT devices into network segments where appropriate. 

A security assessment can evaluate whether connected medical devices are adequately isolated from administrative systems, critical applications, and other sensitive infrastructure.

5. Reduce operational and patient-safety risks

Cybersecurity incidents affecting healthcare environments can have consequences beyond data loss. If an attack affects the availability or integrity of systems supporting clinical operations, the impact may extend into healthcare delivery.

Security testing therefore needs to consider both technical vulnerabilities and operational consequences.

Our Methodology for Hospital IoT Security Assessment

A hospital IoT assessment requires a controlled methodology that considers the sensitivity of healthcare environments and the operational importance of medical technology.

1. Scope Definition and Asset Discovery

The assessment begins by defining the testing scope and identifying relevant assets.

This can include:

• Connected medical devices

• Patient monitoring systems

• Imaging and diagnostic equipment

• Smart laboratory equipment

• IoT gateways

• Network infrastructure

• Wireless-connected devices

• Building-management systems

• Access-control systems

• IoT management platforms

• Cloud-connected healthcare technologies

Asset discovery helps establish visibility across the hospital’s connected environment.

2. IoT Configuration and Security Review

Devices are evaluated for security weaknesses such as:

• Default or weak credentials

• Unnecessary open services

• Insecure protocols

• Outdated software or firmware

• Poor access controls

• Insecure management interfaces

• Unnecessary internet exposure

• Inadequate logging and monitoring

• Weak encryption configurations

The assessment focuses on identifying practical security gaps without unnecessarily disrupting clinical operations.

3. Vulnerability Assessment

Automated and manual techniques can be used to identify known vulnerabilities across relevant systems.

Findings are analysed based on factors such as:

• Severity

• Exploitability

• Exposure

• Asset criticality

• Data sensitivity

• Potential operational impact

This helps security teams prioritise remediation rather than treating every vulnerability equally.

4. Controlled Penetration Testing

Where authorised and technically appropriate, penetration testing can be conducted to validate whether identified vulnerabilities are practically exploitable.

Testing may examine areas such as authentication, network exposure, application interfaces, APIs, device management platforms, and communication channels.

For sensitive medical environments, testing parameters are carefully defined to reduce the risk of service interruption.

5. Network Segmentation Assessment

The assessment examines whether IoT devices are appropriately isolated from other hospital systems.

Testing can evaluate whether an attacker who compromises a connected device could potentially move toward:

• Clinical systems

• Administrative networks

• Servers

• Patient information systems

• Other connected medical devices

6. Reporting and Remediation Guidance

The final stage converts technical findings into actionable recommendations.

A comprehensive report can include vulnerability details, affected assets, risk context, evidence, remediation recommendations, and prioritisation.

Where required, remediation can subsequently be validated through retesting.

Cyberintelsys Hospital IoT Security Services

Cyberintelsys can support healthcare organisations with security assessments covering connected devices, applications, networks, and supporting infrastructure.

1. IoT Security Audit

An IoT security audit evaluates the security posture of connected devices and their supporting infrastructure.

Key areas may include:

• Device configuration

• Authentication and authorisation

• Firmware and software security

• Network exposure

• Communication protocols

• Device management

• Logging and monitoring

• Security policies and controls

2. Vulnerability Assessment

Vulnerability Assessment helps identify known and configuration-related weaknesses across the defined hospital environment.

The assessment can cover IoT devices, servers, network components, applications, APIs, and supporting infrastructure depending on the agreed scope.

3. Penetration Testing

Penetration Testing validates security controls by simulating authorised attack scenarios.

Depending on the environment, testing may cover:

• External infrastructure

• Internal networks

• Web applications

• APIs

• IoT management platforms

• Wireless infrastructure

• Network-accessible medical technologies

4. Medical Device Security Assessment

Connected medical technologies require particular attention because security controls need to coexist with availability and clinical requirements.

The assessment can examine the security posture of network-connected medical devices and identify weaknesses that could expose them to unauthorised access or compromise.

5. Network Security Assessment

Network security testing evaluates segmentation, exposed services, access controls, firewall configurations, communication pathways, and potential attack paths between IoT environments and other hospital networks.

6. Web and API Security Testing

Many modern healthcare technologies use web interfaces, mobile applications, APIs, or cloud platforms.

Testing can identify vulnerabilities involving authentication, authorisation, session management, input validation, access control, and insecure API configurations.
