en.Wedoany.com Reported - TCCA has released a report titled "Cybersecurity in Critical Communications – A Preliminary Overview," aimed at assisting stakeholders in reaching consensus on security standards for critical broadband networks. The report explores the cybersecurity requirements, frameworks, and deployment models during the transition of mission-critical communications to 4G and 5G, and provides recommendations for organizations adopting broadband systems.

Critical communications operators are transitioning from traditional narrowband networks to broadband environments based on 4G and 5G technologies. This shift introduces more suppliers, such as telecommunications equipment manufacturers and application providers, while increasing the number of interconnected systems, thereby elevating security challenges. TCCA points out that new networks rely on open standards and may be more vulnerable to threats, but the industry can draw on decades of mobile network protection experience from the 3GPP ecosystem.

The report emphasizes that organizations should establish internal cybersecurity teams early in the solution design phase and onboard staff with expertise in broadband critical communication threats. A complete critical broadband system includes radio access networks, core networks, mission-critical service providers, devices, and management systems. Since assets come from different suppliers, the supply chain becomes a weak link in security.

Industry bodies and standards organizations play a crucial role in defining cybersecurity requirements. The report aims to create a more consistent approach to mission-critical broadband networks and services across markets, encouraging equipment manufacturers, operators, and application suppliers to enhance collaboration to address the interdependencies arising from multi-layered infrastructure and software in broadband systems.

Filippo Gaggioli, Head of the Cybersecurity Working Group of the TCCA Critical Communications Broadband Group, stated: "As critical broadband communication networks emerge globally, organizations should collaborate to share knowledge and experiences to establish a long-term vision for international standards, providing more robust and secure mission-critical communication solutions for all." Tero Pesonen, Chairman of the TCCA Critical Communications Broadband Group, added: "The network environment for mission-critical broadband networks is significantly more complex, with a greater number of stakeholders compared to traditional narrowband networks. This is an important first milestone in a series of cybersecurity-related efforts within the community." The report marks an early step in the discussion on critical broadband communication security, with TCCA representing users, operators, and suppliers in global mobile standards work.
