Introduction
The growing adoption of connected medical devices is transforming healthcare delivery in New Zealand. Patient monitors, infusion systems, diagnostic equipment, wearable technologies, connected imaging systems, remote monitoring devices and other Internet of Medical Things (IoMT) technologies allow healthcare organizations to collect and exchange information more efficiently.
However, connectivity also introduces cybersecurity risks. Medical devices may communicate with hospital networks, cloud platforms, mobile applications, APIs and electronic health systems. Security weaknesses in one component can potentially create exposure across the wider healthcare environment.
A Medical Device IoT Security Gap Assessment provides a structured way to understand these weaknesses. Instead of focusing only on individual vulnerabilities, a security gap assessment evaluates the difference between an organization’s current security posture and the security controls, practices and safeguards expected for its risk environment.
For healthcare providers, medical device manufacturers and organizations operating connected healthcare technologies in New Zealand, this approach can help identify weaknesses in device security, access controls, network architecture, firmware, applications, APIs, monitoring and incident response.
A gap assessment can also serve as an important starting point before conducting more extensive Vulnerability Assessment and Penetration Testing (VAPT).
Why Medical Device IoT Security Gap Assessment Matters
1. Identify Security Weaknesses Across the IoT Ecosystem
Medical IoT security extends beyond the physical device. A connected device may depend on firmware, mobile applications, APIs, gateways, wireless communication, cloud services and healthcare networks.
A gap assessment evaluates these interconnected components to determine where security controls may be incomplete or inconsistent.
2. Understand the Current Security Posture
Organizations may have security controls in place but lack visibility into whether those controls adequately cover their Medical IoT environment.
An assessment establishes a clearer picture of existing capabilities, including device protection, authentication, encryption, network segmentation, monitoring and vulnerability management.
3. Detect Gaps Before They Become Exploitable
A security gap does not always represent an immediately exploitable vulnerability. However, an unresolved gap can create conditions that increase the likelihood or impact of a future attack.
Identifying these weaknesses early allows organizations to prioritize improvements before they develop into significant security incidents.
4. Protect Sensitive Health Information
Connected medical devices can collect and transmit highly sensitive patient information.
Weak access controls, insecure communication channels, exposed APIs or inadequate data protection can potentially increase the risk of unauthorized access or disclosure.
A gap assessment can highlight where additional safeguards may be required.
5. Strengthen Device and Network Segmentation
Medical devices often operate alongside workstations, servers and other connected systems.
Poor segmentation can potentially allow an attacker who compromises one device to move toward other systems. Assessing network architecture and access controls can help identify opportunities to strengthen isolation between critical environments.
6. Support Security and Compliance Planning
A gap assessment creates a structured roadmap for improving cybersecurity controls.
Instead of implementing security measures without understanding current deficiencies, organizations can prioritize improvements according to risk, business requirements and applicable obligations.
Our Medical Device IoT Security Gap Assessment Methodology
Our Methodology for Medical Device IoT Security Gap Assessment is designed to evaluate the security posture across connected devices and supporting infrastructure.
1. Scope and Asset Identification
The assessment begins by defining the Medical IoT environment and identifying relevant assets.
This may include:
Connected medical devices
IoT gateways
Firmware and operating systems
Mobile applications
Web applications
APIs
Wireless infrastructure
Healthcare networks
Cloud platforms
Backend systems
Third-party integrations
Understanding the technology ecosystem helps establish the boundaries of the assessment.
2. Architecture and Data-Flow Review
The next stage examines how medical devices communicate with other components.
Data flows may be reviewed between:
Medical devices and gateways
Devices and healthcare networks
Devices and cloud platforms
Mobile applications and APIs
Clinical systems and backend databases
This helps identify potentially exposed communication paths and areas where additional security controls may be required.
3. Security Control Assessment
Existing controls are reviewed across multiple security domains.
The assessment may examine:
Authentication and authorization
Password and credential management
Encryption
Device hardening
Firmware management
Secure update mechanisms
Network segmentation
Access control
API security
Logging and monitoring
Vulnerability management
Incident response
Backup and recovery
The objective is to determine whether relevant controls are present, appropriately implemented and consistently applied.
4. Firmware and Device Security Review
Firmware is an important component of Medical IoT security.
The assessment can examine whether the device environment has appropriate protections around:
Firmware integrity
Software updates
Embedded credentials
Debug interfaces
Device configuration
Secure boot mechanisms
Unnecessary services
Third-party software components
Where deeper technical validation is required, firmware analysis and penetration testing can be performed as separate assessment activities.
5. Network and Communication Security Review
Connected devices may communicate through wired or wireless networks.
The assessment evaluates network architecture and communication controls to identify gaps involving:
Network segmentation
Open services
Insecure protocols
Wireless security
Remote access
Device-to-server communication
Excessive network permissions
This helps organizations understand whether Medical IoT devices have unnecessary access to other parts of the environment.
6. Application and API Security Review
Healthcare applications and APIs frequently act as the bridge between devices and users.
The assessment can review areas such as:
Authentication
Authorization
Session management
API access controls
Data exposure
Input validation
Sensitive information handling
Third-party integrations
Where significant weaknesses are identified, VAPT can be recommended for deeper validation.
7. Gap Analysis and Risk Prioritization
Identified gaps are categorized according to their potential security impact.
Rather than presenting a simple list of missing controls, the assessment can prioritize findings based on factors such as:
Criticality of the affected medical device
Sensitivity of processed information
Exposure level
Potential attack paths
Exploitability
Operational impact
Existing compensating controls
This helps security and healthcare teams focus resources on the most important improvements.
8. Reporting and Remediation Roadmap
The final assessment report provides a structured view of the current security posture.
It can include:
Identified security gaps
Affected systems or devices
Risk ratings
Security observations
Potential impact
Recommended controls
Remediation priorities
Suggested next steps
The resulting roadmap can help organizations plan improvements across immediate, medium-term and strategic security priorities.

Controlled penetration testing evaluates whether identified vulnerabilities can be practically exploited.
Testing may cover device interfaces, networks, applications, APIs and other authorized components.
4. Firmware Security Assessment
Firmware-focused testing examines embedded software for weaknesses such as insecure configurations, exposed secrets, outdated components and insufficient update protections.
5. API and Application Security Testing
Medical IoT platforms frequently rely on APIs and applications to exchange information.
Security testing can identify authorization flaws, authentication weaknesses, data exposure and other application-layer vulnerabilities.
6. Network and Infrastructure Security Assessment
