SCADA security specification free download

Critical infrastructures are important to the national interest and people’s everyday life. US National Strategy for Homeland Security has identified 14 areas for critical infrastructure protection. Some of them are information and telecommunication, food energy, water, transportation, finance and banking, emergency services, chemical industry, public health, power grid etc. At the heart and soul of nearly every one of these critical infrastructures is the SCADA (supervisory, control, and data acquisition) system. Therefore, the security of the SCADA system has become a central issue. Unfortunately current security technologies deployed in the SCADA system have many flaws accompanied by endless break-in reports. Eg., in 2006, A Zotob worm has penetrated the firewall of the SCADA system in the Australian Holden Car Factory which has cost about $6m dollar loss overnight. The security strength of a system is not stronger than its weakest part.
