asked Her Majesty's Government:

What participation there was by United Kingdom-based agencies in the exercise Cyber Storm II organised by the United States Department of Homeland Security; what conclusions have been drawn about the readiness of the United Kingdom's critical national infrastructure to withstand a major cyber incident; and whether there are any plans for a United Kingdom-focused exercise. [HL2929]

Representatives of a number of UK government departments and the Centre for the Protection of National Infrastructure participated in the Cyber Storm II exercise as part of the UK Government's commitment to rehearse security procedures and plans regularly. The exercise used UK-based and international scenarios to test the UK's ability to respond to a variety of simulated incidents.

The United States Department of Homeland Security will publish a summary report of the exercise in due course to which the UK will contribute. There are no plans to publish a separate UK report, and we do not announce publicly our future plans for testing security procedures.
