Design on SCADA Test-bed and Security Device

Most of the national critical key infrastructure, such as power, piped gas and water supply facilities, or the high-speed railroad, is run on the SCADA (Supervisory Control and Data Acquisition) system. Recently, concerns have been raised about the possibility of these facilities being attacked by cyber terrorists, hacking, or viruses. Thus, it is time to adopt the relevant security management techniques. This study analyzes the vulnerabilities of SCADA systems through scenarios, designs a test-bed to prove such vulnerabilities, and suggests security devices..
