After 9th May 2018, when the EU’s Network and Information Systems (NIS) Directive is implemented into UK law, such outages would have to be reported to regulators, who have the power to impose financial penalties of up to ?17 million where infrastructure operators have failed to protect themselves against loss of service. Had the service outages occurred after this date, and all the affected organisations were deemed to have failed to protect themselves, the total fines for all affected organisations would cost the UK economy more than ?2.5 billion.
The Freedom of Information requests were sent by Corero, in January and February 2018, to 312 critical infrastructure organisations in the UK, including fire and rescue services, police forces, ambulance trusts, NHS trusts, energy suppliers, transport organisations and water authorities. In total, 221 responses were received, with 155 admitting to having suffered a service outage on their networks in the past two years. In addition, over a third (35%) of the service outages reported in the study were believed to have been caused by a cyber attack.
Andrew Lloyd, President at Corero Network Security, comments: “Service outages and cyber attacks against national infrastructure have the potential to inflict significant, real-life disruption by preventing access to essential services such as power, transport and the emergency services. The fact that so many infrastructure organisations have suffered from service outages points to an alarming lack of resilience within organisations that are critical to the functioning of UK society.
“Across all sectors, we are seeing a greater number of sophisticated and, when undefended, damaging cyber-attacks. Government Ministers and Agencies have reported that these attacks are increasingly believed to be the work of foreign governments seeking to cause political upheaval. The head of the National Cyber Security Centre has already warned that it is a matter of when, not if, the UK experiences a devastating cyber attack on its critical infrastructure. The study poses serious questions about the UK’s current capability to withstand such an attack.”
