Over the past 10 years I have taught students that SCADA systems that are related to infrastructure or manufacturing should be guarded and off of the web if it could not be protected. With computer security hitting headlines everyday, the infrastructure behind America is often overlooked and a natural assumption that our infrastructure is safe can be misleading. Being on the internet, critical systems (SCADA) are computer systems that control many necessary and vital things such as electrical power, manufacturing, communications, water treatment, waste water, oil and gas systems.
Even when SCADA systems are protected properly, security analyst also have to look at the remote access into these systems from home computers of workers who may be on call. Infections from botnets, worms, viruses or vulnerabilities on home computers could possibly lead to infections on the SCADA systems. Work based computers that are given to workers (laptops, tablets, netbooks) should be used for work only and by the employee only. The computers (issued to the employee) should be locked down and encrypted when communicating with the SCADA system and the computer should not allow any other type of access to the web.
A recent ZDNet article, China’s cyber-militia behind U.S. blackouts? is an excellent article on the research and analysis of reports suggesting that China may be behind blackouts in the Northeast and in Florida. The article truly concludes that regardless of who may have broken in or who may have caused the blackouts the threats against our infrastructure is real.
