Summary of NCSC’s security analysis for the UK telecoms sector

Since the initiation of the DCMS Supply Chain Review in September 2018, the NCSC has performed an extensive and detailed analysis of the security of the telecommunications (telecoms) sector.

The outcomes of that analysis are now being provided through a blog by NCSC’s Technical Director, our formal advice on the use of High Risk Vendors (HRVs), and through this document, a summary of NCSC’s security analysis for the UK telecoms sector. Specifically, this document summarises the NCSC’s technical recommendations for improving the security of the UK’s telecoms sector, alongside a description of our technical security analysis that we used to derive these recommendations.
