Amateur cyber defenders will compete to protect the City of London from a simulated cyber attack.
Amateur cyber security experts are participating in the 2014 Cyber Security Challenge Masterclass held at Churchill’s underground bunker.
The competition, which aims to protect the City of London from a simulated cyber attack, is expected to help the recruitment of next generation tech talent and highlight the predictable major cyberattack on the nation’s critical infrastructure.
Cyber Security Challenge UK CEO Stephanie Daman said:"The combination of government organisations, multinational technology and defence companies and one of the largest telecommunication companies in the world working together to secure the future of the profession makes today a really special occasion.
"We hope the excitement of the next few days will not only inspire many of our hugely talented finalists to lend their skills to the cyber security profession, but also encourage many more people from across the UK to sign up with us and test their skills in nextyear’s competitions."
The masterclass has been developed by cyber security experts from BT, GCHQ, the National Crime Agency (NCA), Juniper Networks and Lockheed Martin.
GCHQ Government and Industry Cyber Security Director General Ciaran Martin said that there is a need for more, high quality people in all sectors of the economy working on cyber security.
"That’s why the Challenge is so valuable and why GCHQ is proud to be a sponsor," Martin said.
