SCADA Systems

                SCADA refers to the industrial control system.  This is the program that is used to control water and sewer pipelines.  SCADA controls traffic lights and windfarms.  SCADA has very low security because they aren’t connected to the internet and are physically secure, so there is a naïve belief that they are safe.  SCADA, much like any other system that is connected to a network, can be vulnerable in many ways and can be a potential target for a cyber-attack.  One reason that SCADA becomes vulnerable is inadequate authentication mechanisms.  SCADA systems were designed for isolated environments so there was no need for authentication credentials.  Another vulnerability is that SCADA systems often employ proprietary communication protocols that lack encryption.  Not having any kind of encryption can be detrimental to the software, which in turn would be extremely bad if it became compromised.  Vulnerabilities can become a real problem for some companies, especially if the equipment they are using isn’t receiving or cannot receive regular updates due to the terminals being legacy terminals.  Legacy terminals are referred to terminals that can no longer receive security patches due to the firmware that can no longer be updated.  Since they are legacy computers and can no longer receive security patches that makes them very susceptible to a cyber-attack.  There are a few ways to combat these potential attacks.  Enable authentication and enforce multifactor authentication.  Install and implement VPNs.  Apply end-to-end encryption.  Establish a patch management process.  The SCADA system seems safe because it appears disconnected to the rest of the world, but this is something that dramatically needs to be protected.
