    Telefónica Argentina deploys firewall for SS7 and Diameter-based signalling

    -

    Mavenir solution leverages artificial intelligence (AI), including machine learning (ML), to protect Movistar customers.

    Telefónica Argentina (which operates under the Movistar brand) has deployed Mavenir’s Signaling Firewall to protect its customers and signalling infrastructure by detecting and preventing signalling-based attacks, and tracing their origin.

    The signalling fraud solution is said to stop signalling hacks and distributed denial of service attacks (DDoS) to prevent customers’ information from being intercepted and improve user experience.

    The deployment of a signalling firewall in the Telefónica Argentina network will handle SS7 and Diameter-based signalling coming from abroad and other networks.

    A problematic situation

    Signalling system 7 (SS7) might be thirty years old, but it is in wide use and will be so for many years to come.

    Signalling transfer points (STP) play a critical role in SS7 infrastructure, routing and relaying signalling messages between end points and other transfer-points: in some instances, these end-points are multiplying, but the maturity of the technology means support for STPs is increasingly scarce, which is a big concern to operators.

    Minimal signs of decline

    Analyst Greg Collins, founder of Exact Ventures, reckons there were 284 million STP message signal units (MSUs) worldwide at the end of 2018, which despite major network tech upgrades, most notably 5G, will only decline to 258 million MSUs – or by just 2% annually on average.

    He also pointed out that at the end of 2018, fewer than 20% of subscribers used voice over LTE for voice, and expects that in 2023, 3.9 billion – more than half the world’s voice subscriptions – still use 2G and 3G networks.
