Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what assessment her Department has made of the potential merits for cyber resilience of maintaining communications systems with differing architectures and modes of delivery.

The government recognises the importance of resilient communications networks and services. Telecommunications providers are required to take appropriate and proportionate measures to identify, reduce, prepare for and recover from risks to the security and resilience of their networks and services under the Communications Act 2003, as amended by the Telecommunications (Security) Act 2021. The government works closely with Ofcom and industry to strengthen telecommunications resilience and to ensure providers are able to manage a range of risks, including cyber threats, through appropriate resilience and security measures. These measures may include maintaining different communications architectures and modes of delivery, although this is not, in general, legally mandated.
