Critical Infrastructure are those facilities, systems, sites, information, people, networks and processes, necessary for a country to function, which if lost or compromised would lead to severe economic or social consequences, or to loss of life.

Critical Infrastructure has been rapidly digitised, with physical parameters often controlled by Industrial Control Systems.

Alongside the historic physical threats, such as explosives, the emerging cyber-physical world brings new threats in the form of cyberattacks for sabotage. Recent examples include the Stuxnet attack on an Iranian nuclear facility and the more recent attacks on a German Steel Mill and the Ukranian power grid.

Researchers across Imperial Collge are working to understand and 
counter the different types of threats facing critical infrastructure.
