A cyber risk assessment for emergency medical services (EMS) is a comprehensive evaluation designed to identify and prioritize potential cybersecurity threats to the systems and networks that support EMS operations. Given the critical role EMS plays in public safety and patient care, ensuring robust cybersecurity is paramount. Below is an outline of what such an assessment typically involves:

​

1. Asset Identification and Inventory

• Systems and Devices: Catalog all digital assets, including dispatch systems, electronic patient care reporting (ePCR) systems, communication networks, mobile devices in ambulances, and connected medical devices.

• Data Assets: Identify sensitive information such as patient records, personnel data, and operational data that require protection.

• Physical and Virtual Assets: Include both on-premises hardware (servers, routers) and cloud-based services that support EMS operations.

​

2. Threat Identification

• External Threats: Consider cybercriminal activities such as ransomware, phishing, Distributed Denial of Service (DDoS) attacks, and intrusion attempts from hackers targeting emergency communications.

• Internal Threats: Account for insider threats (intentional or accidental), such as employees mishandling data or falling for phishing scams.

• Emerging Threats: Leverage cyber intelligence sources to understand new tactics used by threat actors, especially those that target healthcare and emergency services.

​

3. Vulnerability Assessment

• System Vulnerabilities: Perform network and application vulnerability scans to identify outdated software, misconfigurations, unpatched systems, and insecure endpoints.

• Process Vulnerabilities: Evaluate operational procedures for handling cybersecurity incidents, data backups, and access control policies.

• Compliance Gaps: Review adherence to industry standards (e.g., HIPAA, NIST) and local regulations related to emergency services.

​

4. Risk Analysis

• Likelihood: Estimate the probability that a particular threat will exploit a vulnerability. For EMS, consider factors such as the public-facing nature of dispatch systems or vulnerabilities in legacy equipment.

• Impact: Assess the potential consequences if a threat were realized. For EMS, this could mean disruption of life-saving services, compromised patient data, or financial and reputational damage.

• Risk Matrix: Use a risk matrix to categorize risks as low, medium, or high based on likelihood and impact.

​

5. Mitigation Strategies

• Technical Controls: Recommend improvements like patch management, robust firewalls, intrusion detection systems (IDS), encryption, and multi-factor authentication.

• Operational Controls: Enhance incident response plans, provide employee cybersecurity training, and improve network segmentation to isolate critical systems.

• Administrative Controls: Update policies and procedures, conduct regular audits, and implement continuous monitoring to keep pace with evolving threats.

​

6. Reporting and Recommendations

• Risk Report: Compile a detailed report that documents identified vulnerabilities, potential threats, risk levels, and recommended mitigations.

• Prioritization: Focus on high-risk vulnerabilities that directly impact patient care and operational continuity.

• Action Plan: Develop a timeline and assign responsibilities for implementing risk mitigation measures.

​

7. Continuous Monitoring and Review

• Ongoing Assessment: Establish a continuous monitoring program to track changes in the threat landscape and ensure that the implemented controls remain effective.

• Periodic Reviews: Schedule regular risk reassessments to adapt to new technologies, regulatory changes, and emerging threats.

A cyber risk assessment for emergency medical services is an essential process to ensure the security and resilience of EMS operations. By systematically identifying assets, vulnerabilities, and potential threats—and by implementing robust mitigation strategies—EMS organizations can better protect critical systems, ensure continuity of operations, and maintain the trust of the communities they serve. This proactive approach not only reduces the likelihood of a cyber incident but also prepares the organization for a swift, coordinated response should an incident occur.
