Security of UK Telecommunications

Key points: 

  • Telecommunications (telecoms) have been recognised by the Government as one of 13 critical national infrastructure sectors – a term signifying infrastructure that is pivotal to the functioning of the UK.
  • Concerns have been raised recently about the security of telecoms networks, including undersea cables that transmit an estimated 97% of global communications and $10 trillion of financial transactions every day.
  • Threats to telecoms can be classified as physical or cyber, and can be malicious, non-deliberate, or the result of a natural disaster. Examples of threats to telecoms include cable damage, power and system failures, flooding and cyber-attacks.
  • The Communications Act 2003 requires telecoms companies to take measures to maintain the security and resilience of their networks. While there is no mandated security and resilience standard for telecoms, Ofcom and others produce guidance on what measures telecoms companies should take in order to meet their obligations under the Communications Act.
  • Physical resilience measures include investing in duplicates of infrastructure, installing back-up power supplies, and protecting infrastructure using defences around site premiers. Cyber resilience measures include preparing a data breach plan and using anti-virus software.

  • The use of technology to perpetrate domestic abuse, referred to as tech abuse, has become increasingly common. Domestic abuse charity Refuge reported that in 2019, 72% of women accessing its services said that they had been subjected to technology-facilitated abuse. Common devices such as smartphones and tablets can be misused to stalk, harass, impersonate and threaten victims. Some groups have raised concerns that the growing use of internet-connected home devices (such as smart speakers) may provide perpetrators with a wider and more sophisticated range of tools to harm victims. How is technology being used to perpetrate domestic abuse, how can this be prevented and what role can technology play in supporting victims?

  • People’s behaviour has a major role in the success of test, trace and isolate programmes. Uncertainty about whether to report symptoms, low perceived risk of COVID-19 disease and concerns about the consequences of self-isolation are among the barriers to adherence. Has the Scientific Advisory Group for Emergencies looked at adherence to TTI? What evidence is there on people’s understanding and willingness to be tested, provide contact details and self-isolate? Is there anything that can be done to improve this?

  • Test, trace and isolate programmes across the UK are under pressure as COVID-19 cases rise in all age groups and demand for tests grows. Further pressure comes from people seeking tests because they have symptoms caused by other respiratory viruses but need a test in order to rule out COVID-19. The Scientific Advisory Group on Emergencies has described the impact of current test and tracing on the transmission of the virus as “marginal”. How does test and trace work and what are the current challenges limiting its effectiveness in reducing COVID-19 cases?
