5G Healthcare Security Risks and Statistics
How 5G Expands the Healthcare Attack Surface
5G Healthcare Use Cases
5G technology is revolutionizing healthcare with applications that were once unimaginable. It enables robotic surgeries with ultra-low latency, links ICU devices like ventilators, cardiac monitors, and infusion pumps for real-time monitoring, powers smart ambulances to transmit diagnostic data while en route, and speeds up AI-driven imaging analysis. However, with these advancements come new vulnerabilities. Each connected device or system becomes a potential entry point for attackers, meaning a single breach could compromise entire networks. In essence, these diverse applications significantly increase the risk landscape.
5G Technical Features That Increase Risk
The architecture of 5G differs fundamentally from earlier network technologies, introducing unique security challenges. For instance, network slicing - which allows multiple virtual networks to run on the same physical infrastructure - can be exploited if one slice is compromised, potentially allowing attackers to pivot to others. Additionally, 5G's reliance on virtualization and cloud computing shifts many network functions from hardware to software, expanding the attack surface to include cloud providers and their security measures.
The massive IoT capacity of 5G is another concern. With the ability to support up to 1 million connections per square kilometer, hospitals can connect far more devices than before. Unfortunately, many IoT devices prioritize affordability and ease of use over robust security measures [3][4].
Moreover, the distributed nature of 5G networks, which relies heavily on edge computing and device-to-device communication, complicates centralized monitoring. Traditional security controls may no longer capture all network traffic, creating blind spots where malicious activity can go undetected [3]. These vulnerabilities make 5G-powered healthcare systems more susceptible to cyberattacks, posing serious risks to both operations and patient safety.
Patient Safety and Operational Consequences
The security issues tied to 5G aren't just technical - they have direct and potentially devastating impacts on patient care. A breach in 5G services or among vendors could jeopardize patient safety in several ways. For example, if connected medical devices lose network access due to a security incident, clinicians might be unable to retrieve critical real-time data, delaying care. Worse yet, tampered data transmitted over compromised networks could lead to incorrect diagnoses or medication errors. Ransomware or botnet attacks could render essential devices like ventilators or infusion pumps inoperable, creating life-threatening situations.
The high speed and bandwidth of 5G, while beneficial for legitimate uses, also work in favor of attackers. Cyberattacks, such as botnets or ransomware, can propagate across networks faster than security teams can respond. With up to 1 million connections per square kilometer, attackers can launch large-scale traffic assaults using numerous compromised devices [3]. This enhanced connectivity and bandwidth also allow hackers to steal vast amounts of sensitive patient data in a fraction of the time it would take on older networks. The stakes in securing 5G healthcare systems couldn't be higher.
Vendor Risk and Network Security Challenges in 5G Healthcare
The 5G Healthcare Vendor Ecosystem
The 5G healthcare landscape involves a complex web of interconnected players, each contributing to the delivery of connected care. This ecosystem includes network providers like AT&T, Verizon, and T-Mobile, manufacturers of medical devices, cloud service providers such as Amazon Web Services, Microsoft Azure, and Google Cloud, and AI analytics companies. Together, they form the backbone of 5G-enabled healthcare.
However, this interconnectedness brings its own set of challenges. When multiple vendors share responsibilities, pinpointing accountability becomes tricky. A security flaw in one vendor's product can ripple across the entire system, complicating efforts to identify who should fix the issue - or who bears liability if patient safety is compromised [5].
Primary 5G Risk Areas
Three main areas of concern dominate the security conversation in 5G healthcare:
- Outsourced IoT Device Development: Many Internet of Things (IoT) devices used in healthcare are developed by third-party manufacturers who may not prioritize security. This creates a disconnect in security practices between device makers and healthcare providers, leaving vulnerabilities unaddressed [1].
- Data Privacy Risks: The speed and capacity of 5G networks allow for the transmission of massive amounts of sensitive patient data. While this improves efficiency, it also increases the risk of rapid and large-scale data breaches compared to older network technologies.
- Operational Dependencies on Vendors: Healthcare organizations often rely on third parties to manage critical infrastructure. A failure by one vendor - whether due to technical issues or a security breach - can disrupt patient care [3].
To tackle these risks, U.S. regulations emphasize the need for clear vendor accountability and enforce stringent security protocols.
U.S. Regulatory Requirements for Vendor Risk Management
Healthcare providers must adhere to various regulations, including HIPAA, HITECH, FDA cybersecurity guidelines, and state-specific laws, to ensure that vendors meet established security standards. Formal agreements between healthcare organizations and vendors are essential to enforce compliance.
The FDA has highlighted the growing gap between medical device security measures and the rapid pace of new device introductions [1]. Meanwhile, federal bodies like the Department of Homeland Security (DHS), Cybersecurity and Infrastructure Security Agency (CISA), National Institute of Standards and Technology (NIST), and Federal Communications Commission (FCC) are actively shaping 5G security standards and publishing threat models [6].
NIST’s National Cybersecurity Center of Excellence (NCCoE) has developed a 5G cybersecurity project that offers a security reference architecture for 5G networks. Key publications, such as NIST SP 1800-33A (Executive Summary) and NIST SP 1800-33B (Approach, Architecture, and Security Characteristics), provide actionable guidance for securely designing and operating 5G networks [7]. At the state level, laws like California’s CCPA (California Consumer Privacy Act) impose stricter controls on data management, which is increasingly vital as 5G networks handle larger volumes of patient information [8].
How to Assess 5G Vendor Risk
5G Vendor Risk Assessment Framework
Healthcare organizations need more than just basic checklists to evaluate 5G vendor risks effectively. A structured framework is essential - one that looks at both technical controls (like endpoints, MEC, RAN, NFV, network slicing, and IoT devices) and managerial controls (such as governance, personnel, and operations) [9].
To strengthen these evaluations, adopting a Zero-Trust Architecture (ZTA) is key. This approach examines four critical dimensions:
- Subject (users, devices, applications)
- Object (data, platforms, services)
- Environment (security context)
- Behavior (access patterns) [3].
When assessing vendors, healthcare organizations should scrutinize their cybersecurity policies, patch management processes, incident response strategies, and compliance with frameworks like the NIST Cybersecurity Framework. The goal? To ensure vendor practices align with the unique challenges that 5G technology introduces to patient care environments. This framework sets the stage for thorough and effective vendor evaluations.

Putting this framework into action can be complex, but tools like Censinet RiskOps™ make it much easier. This platform automates vendor risk assessments, reducing manual work and providing continuous visibility across the intricate 5G ecosystem. It allows healthcare organizations to conduct detailed security questionnaires, validate vendor-provided evidence, and monitor risks continuously - moving beyond the outdated approach of annual, point-in-time reviews.
With Censinet AITM™, third-party risk assessments become faster and more efficient. Vendors can complete security questionnaires in seconds, while the platform automatically summarizes their documentation, highlights key product integration details, and identifies fourth-party risk exposures. The platform’s command center offers real-time risk visualization, helping security teams pinpoint which vendors pose the highest threats to patient safety. This centralized, proactive approach is especially important in 5G environments, where multiple vendors - ranging from network providers to AI analytics companies - must be monitored simultaneously.
Risk Scoring Matrix for Patient Safety
Not all vendor risks are created equal, especially when it comes to their impact on patient care. Healthcare organizations should adopt a risk scoring system that ties vendor vulnerabilities directly to potential clinical outcomes. This matrix should evaluate factors like:
- The vendor's access to patient data
- Their involvement in critical care systems
- The consequences of service disruptions or security breaches
For example, vendors managing systems that affect patient monitoring, diagnostic equipment, or emergency response should be prioritized. A 5G-connected infusion pump vendor, for instance, would score higher on the risk scale compared to a vendor providing administrative software. This patient-focused scoring ensures that security resources are directed where they matter most - protecting the critical aspects of care delivery and supporting the overarching mission of healthcare organizations.

Solutions for Secure 5G Healthcare Deployments
Reducing IoT and Device Risks
With the expansive connectivity brought by 5G, healthcare organizations face increased vulnerabilities, especially from IoT devices. Addressing these risks starts with adopting a Zero-Trust Architecture. This approach assumes no user, device, or application is trustworthy until thoroughly verified. It incorporates continuous identity authentication, least privilege access, and dynamic controls while segmenting networks to isolate critical devices. For instance, a 5G-connected infusion pump should operate on a separate network segment from administrative systems, minimizing potential damage if one segment is compromised [3][11].
Strong authentication practices are also non-negotiable. By deploying unified Identity and Access Management (IAM) and Multi-Factor Authentication (MFA), healthcare organizations can eliminate outdated access privileges and ensure devices are registered using trusted hardware. This is vital, especially considering incidents like the FDA's 2017 recall of half a million pacemakers due to vulnerabilities that allowed hackers to drain batteries or manipulate heartbeats [11].
Another critical step is centralized patch management, which ensures timely updates across devices, even older ones that are harder to upgrade. This requires cooperation among multiple stakeholders [11]. Coupling patch management with robust data encryption - both at rest and in transit - adds another layer of protection. Even if attackers breach the network, encrypted patient data remains unreadable [3][11]. Real-time monitoring and distributed security tools provide the visibility needed to counter threats from technologies like multi-access edge computing (MEC) and Device-to-Device (D2D) connections. Together, these measures strengthen device-level security and set the stage for broader infrastructure oversight.
Improving Visibility into Vendor-Managed Infrastructure
The intricate 5G infrastructure, built by multiple vendors and reliant on cloud, virtualization, and software-defined networking, introduces significant supply chain risks [10]. To address this, healthcare organizations must establish clear contractual security baselines. These agreements should outline security requirements, incident response protocols, and compliance standards before vendors are entrusted with critical infrastructure.
Shared monitoring tools can help eliminate blind spots between healthcare organizations and their vendors. Instead of relying solely on vendor reports, organizations should implement continuous monitoring of external interfaces [12]. Explicit Service Level Agreements (SLAs) are also essential, covering metrics like response times for security incidents, patch deployment schedules, and audit rights. These measures allow healthcare organizations to independently verify vendor security practices. Considering healthcare data is valued at approximately $408 per record - making it 50 times more valuable than data in other industries [2] - these protections are indispensable for safeguarding patient information.
