Recommendation 14

The impacts of catastrophic disruption from a co-ordinated attack remain speculative, but are almost certainly highly damaging. We estimate they would include payment and supply chain failures, some degraded communications, overstretched emergency responses, and unexpected cascading issues—all at a time of crisis. We are not convinced there are currently adequate sector-by-sector assessments of reliance on subsea cables, or sufficiently detailed plans for handling cascading consequences if data rerouting stops working properly. We are pleased the Government is starting to address this, with a particular focus on the finance sector. (Conclusion, Paragraph 98)
