How 5G Changes the Telecoms Risk Dynamic

RAG TV has been broadcast for the last 17 Wednesdays in a row, and making a weekly interview show has proven to be an extraordinary experience for me. Nothing compares to the opportunity to learn by putting questions to the world’s foremost experts. This week’s show was graced by Michele Zarri (pictured, left) who taught over 300 regulators about 5G whilst he was Technical Director of the GSMA; he now serves as a Vice President at Mobileum, helping them to enrich their product portfolio in response to the demands created by 5G. Michele was in the interview hot seat, whilst David Rogers MBE helped with the friendly cross-examination and also contributed his own insights. David is another man who has been both an educator and an instigator of change, having delivered university courses on cybersecurity and acted as a prime mover in the setting of new standards and codes of practice.

I like to think that RAG TV has also played a role in providing education to professionals, thanks to the generosity of teachers like Michele and David. The methods used by RAG TV may seem unconventional compared to how we normally conceive of professional training, but will be familiar to anyone who has ever participated in university tutorials. Sometimes we need the cut and thrust of interaction to open up ideas and examine them more deeply. That is why I have so enjoyed my part in Season 3 of RAG TV, though next week’s show will be the last in the current run as RAG’s attention turns to RAG London 2021, our first physical conference since lockdown.

In the meantime, listen to what Michele and David had to say about:

  • the extent to which 5G changes the operating risk parameters of mobile operators;
  • managing the complexity that comes with more specific SLAs for different customers;
  • the shifting balance between preventative and detective controls;
  • competition between the AI techniques used by criminals and businesses;
  • changes in the ways telco risk managers will need to approach their work;
  • whether automation will alter what is perceived to be a mistake or vulnerability;
  • the need to make technology audits more systematic and extensive;
  • properly evaluating risks created by the internet of things; and
  • the need for new cybersecurity laws.
