Strengthening Resilience: 150 Years of Telecommunication and the cybersecurity Challenges Facing Emergency Services

The year 2026 marks a significant milestone: 150 years since the first telephone call. This groundbreaking invention revolutionized human communication and laid the foundation for modern emergency response systems, which increasingly rely on advanced telecommunication capabilities. However, this enhanced connectivity also exposes emergency services to a growing array of cybersecurity threats.

The theme of this year’s World Telecommunication and Information Society Day, “Strengthening resilience in a connected world,” is particularly relevant in light of these challenges. Recent data from the European Emergency Number Association (EENA) highlights the alarming frequency of cyberattacks targeting public safety organizations across Europe. On average, emergency control rooms experience cyberattacks every 3.3 days, with an 89% increase in disruptions to critical dispatch and call-handling systems over the past year.

Ransomware gangs and AI-driven campaigns are increasingly targeting these essential services, exploiting the fact that first responders cannot afford operational downtime when lives are at stake. Addressing this challenge necessitates a shift from reactive risk management to a proactive approach focused on operational resilience. This involves implementing security measures at every layer of technology, from hardware to software, ensuring that the highest standards of cybersecurity, redundancy, interoperability, and sustainability are integrated into every device, solution, and network.

Mastering the Transition to Critical Communications

Public safety agencies across the EMEA region are undergoing a significant technological transition. Responders are moving away from legacy narrowband radio systems like TETRA and are increasingly adopting broadband critical communications networks based on 4G and 5G architectures. This shift to Mission Critical Services (MCX) offers numerous advantages, including data-rich applications, real-time video streaming, and enhanced situational awareness.

Interoperability is essential for overcoming the technical challenges associated with this infrastructure update. As agencies transition to new mobile networks, their devices and data systems must communicate seamlessly across local jurisdictions, national borders, and varying technological standards. Dual-device strategies can provide a reliable bridge between older and newer systems, while 5G ‘tactical bubbles’ can maintain real-time situational awareness even when core infrastructure is temporarily unavailable. These strategies are crucial for ensuring that operations continue smoothly and that teams remain safe, even in the event of cellular network failures.

Embedding a Defence-in-Depth Security Strategy

In a digital environment, mobile devices serve as the primary tools for intelligence gathering, identity verification, and coordination. Therefore, every mobile platform must be ruggedized and configurable to ensure resilience within the public safety operational landscape. Achieving true resilience by design requires a ‘defence-in-depth’ strategy, which integrates security measures at every layer to mitigate the broader attack surface resulting from increased reliance on mobile technologies. Key components of this strategy include:

• System Integrity: Secure Boot and Verified Boot work in tandem to establish a continuous, unbroken hardware chain of trust from the moment the device powers on until the operating system is fully loaded.

• Hardware-Level Trust and Secure Element: Security must be embedded at the hardware level, utilizing hardware-based security extensions to create a Trusted Execution Environment (TEE) and a Secure Element (SE) for the secure storage of sensitive cryptographic keys. The SE acts as a physically isolated digital vault for key storage.

• End-to-End Encryption: All operational data must be encrypted, whether stored on the device or transmitted across the network, to protect sensitive information from unauthorized access.

• Strict Certification and Compliance: Public safety technologies must meet rigorous security certifications. Hardware and software should comply with relevant laws, including the upcoming EU Cyber Resilience Act (CRA), which establishes mandatory cybersecurity requirements, and the EU’s Network and Information Security Directive (NIS2).

• Advanced Authentication for Shared Assets: Given that shift personnel frequently share mobile devices, agencies should consider advanced access solutions, such as biometrics, to prevent sophisticated spoofing attacks and ensure secure shift transitions with a clear audit trail.

• Proactive Lifecycle Protection: Updates should be delivered proactively to address potential threats before they escalate. Guaranteed lifecycle support is essential for defending against rapidly evolving software vulnerabilities and ensuring continuous operational stability.

Driving Frontline Readiness with Total Asset Visibility

Beyond secure networks and devices, physical readiness is another critical pillar of resilience. Clear visibility over physical assets can save rapid response teams valuable time and free up resources for other frontline services. Delays in locating essential equipment can have serious consequences; in high-pressure situations, officers cannot afford to waste time verifying whether they have the necessary gear.

Utilizing radio frequency identification (RFID) technology enables agencies to assign a ‘digital voice’ to every physical item. This technology facilitates:

• Automated Vehicle Checking: RFID allows officers to quickly verify their equipment at the start of a shift, immediately identifying what is on board and what is missing, significantly reducing preparation times.

• A Digital Chain of Custody: RFID provides an automated method for documenting the chain of custody, enhancing everything from evidence tracking to arms management, thereby building public trust.

• Lifecycle Management: Uniforms and protective equipment can be monitored from deployment to decommissioning, ensuring that gear remains fit for purpose and reducing costs through effective lifecycle management.

The 150th anniversary of the telephone serves as a timely reminder of the importance of supporting public safety frontline workers. They require devices designed for secure mobile digitization, smart data capture, robust asset visibility, and compatibility with next-generation networks. This comprehensive approach to resilience is essential for connecting and protecting first responders and the communities they serve.
