The Deputy Director of the NSA, Richard H. Ledgett Jr., warned of industry’s reliance on industrial control systems (ICS) in his keynote address for the Joint Service Academy Cyber Security Summit at the US Military Academy. In recent years, ICS has become less obscure, but providers have not adequately addressed threats to their security. Cyber attacks can cause significant damage to infrastructure, such as the four-month blackout of the Ukrainian power grid. Ledgett warned, “Any system is only as strong as its weakest link.” See: http://www.defense.gov/News-Article-View/Article/740177/critical-infrastructure-vulnerable-to-attack-nsa-leader-says.
