SCADA systems stands for supervisory control and data acquisition. Which are normally just referred to as industrial control systems. These systems include water processes, pipelines, water treatments, wind farms, electricity, and etc. They also extend to actual facilities and production sites. According to the article the SCADA system is under questioning because they believe it could be attacked by cyber warfare. The security of these systems are very important considering they control systems that directly relate to our everyday lives. There are numerous checks of vulnerabilities that our critical infrastructure faces. The first being that some are on a network. So the possibility of a cyber attack is possible if the right security measures are not in place. The next vulnerability is the access point. If someone has access to the critical infrastructure, they could easily change, or insert virus into the system. Another vulnerability is the little security we have in packet control. Anybody sending packets is technically in control. These are just simple vulnerabilities of the critical infrastructure system. There are vulnerabilities that we can not control. Those vulnerabilities are weather, natural disasters, malfunctions, etc. The good thing about the protection of all this is the fact that SCADA has a good system in place to mitigate all these risks. The system has RTU which in term puts restrictions on the host. The supervisor has reign over the host in a sense if he/she needs to, they can override the system themselves. The Humane interface gives a live look at the data. So if anything is wrong they will immediately see in the system. The SCADA system also has a “back up system” . They have components of the distributed control system. They have smart programs installed in them to perform functions without having a master computer running it. SCAD has a strong communication system. They send signals throughout the system. There are still some vulnerabilities within the system like I’ve already mentioned. But for the most part they can be taken care of. The SCADA has a well put system together to mitigate vulnerabilities.
