Signaling Firewalls, Network Resilience and Teenage SIM Swappers: Commsrisk Show 3

Are we building too much upon the insecure foundations of our networks? Failures can occur by both accident and design.

Yesterday’s episode of The Communications Risk Show featured network security blogger Josué Martins (pictured right). He drew on his experience at Samsung, Unitel and Accenture whilst discussing the need for signaling firewalls and the ways they can be incorrectly configured or inadequately maintained. The co-existence of different signaling protocols and the sensitivity of private information communicated by networks are just two of the reasons why telcos need to ensure there are no gaps in signaling firewalls.

Our topical chat also covered the surge in prosecutions for boys and young men who have used SIM swaps and bribed telco staff as part of a settled strategy for committing crime. The ultimate goal is to hack businesses to steal data and demand ransoms but comms providers provide a convenient and recurring waypoint for their illegal activities. Will the recent high-profile prosecutions represent a turning point that discourage other juveniles from committing similar crimes? Or have we passed the point of no return because so many kids are now using Telegram and Discord to teach each other criminal techniques like social engineering?

There have also recently been some embarrassing network outages, with some caused by hackers, whilst others simply involved more load than a network could cope with. San Francisco provided one stunning example of the extent to which everything could become over-reliant on networks, as a string of self-driving ‘robotaxis’ all came to a standstill in the middle of the road at the same time. The cars blocked traffic in every direction but could not be restarted by remote human operators because network congestion prevented communication with each car’s systems. It is natural for comms businesses to want more and more products and services to depend on network connectivity, but might we soon regret networking machines and devices that never needed to be networked before? And will network operators put themselves at risk by becoming liable for much more serious failures than the temporary inability to make a call?
