Understanding NIS2 and its impact on roaming security in Europe
So, what is NIS2?
The NIS2 directive is an EU legislation aimed at enhancing cybersecurity and protecting critical infrastructure. Unlike previous documents, NIS2 is legally binding, requiring compliance across various sectors called “critical infrastructure industriesâ€, including telecommunications, energy, healthcare, and transport, which are increasingly interconnected through IoT M2M technologies. While GSMA and GDPR provide the main guidelines for telcos, NIS2’s comprehensive legal framework safeguards Europe's entire critical infrastructure. This directive marks a significant evolution, as it unifies the cybersecurity approach across multiple sectors, reflecting the growing interdependency and technological advancements of our time.
Deutsche Telekom Global Carrier?at the forefront of NIS2
Deutsche Telekom has been instrumental in the NIS2 initiative, supported by Germany’s robust regulatory framework. The country’s Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik) plays a key role in enforcing these measures. Its IT Security Act (IT-Sicherheitsgesetz) has been updated to align with NIS2 requirements. The NIS2 directive is being implemented not only in Germany, but across all of Deutsche Telekom’s national company networks to secure our own digital ecosystems, as well as those of our partners and subscribers. The procedure is still ongoing and involves different internal processes related to security, starting from enhancing cybersecurity infrastructure and trainings, and finishing with several new concepts, such as Magenta Security Roaming, to ensure compliance with new security guidelines.
How and why will NIS2 impact the telco industry?
NIS2 targets IoT M2M traffic over 4G/5G, necessitating a significant adaptation in telco security. With over 6 billion connected devices projected by 2028 and expected revenue over $70 billion for service providers (source: Kaleido) we see how fast and massively the numbers are growing – it means, that telecom operators and critical infrastructure enterprises behind must urgently evolve to meet new security requirements.?Current IoT M2M security challenges include GT lease abuse, man-in-the-middle attacks, DDoS attacks, and signaling storms. According to Juniper Research, the complexity of securing IoT M2M devices in roaming scenarios is particularly high due to the diverse and dynamic nature of international networks. In addition, Kaleido Intelligence conducted a survey which finds that only 3% of enterprises have access to detailed information over traffic and device behavior from their IPX Providers. Almost half of all operators (43%) taking part in the research also said that to mitigate the risks related to IoT M2M security, they expect security measures to be undertaken by their service providers. NIS2’s focus on enhanced risk management, incident reporting, cross-sector collaboration, regulatory oversight, and supply chain security will significantly bolster the protection of critical infrastructure, ensuring robust and resilient telecom networks – and steering service providers to answer such requests coming from operators.
