Supervisory Control and Data Acquisition (SCADA) is a system of software and hardware elements that allow industrial organizations to gather and monitor real time data. According to Eleks, “SCADA provides revolutionary data for organizations’ ‘. These systems can quickly alert an operator if a batch or product is not functioning properly, indicating a high number of errors. These error notifications allow the operator to mitigate and resolve issues as well as prevent further problems and loss of product. The ability to understand the components of SCADA systems and their functions allow us to see where vulnerabilities are likely to arise. SCADA systems are Industrial control systems (ICS) that provide supervisory level control over machinery/industrial processes. These systems contain supervisory computers such as Programmable Logic Controllers (PLCs), Remote Transmission Units (RTUs). Both systems have sensors that receive commands from and send information to other components of the SCADA systems. PLCs and RTUs collect data that help plant supervisors make crucial decisions based on real time information. Supervisors only need to look a t the Human Machine Interfaces (HMIs) where functions and elements of SCADAT are presented for human review and control. Unfortunately, according to reports received, vulnerabilities have and will continue to be a problem plaguing SCADA systems. SCADA system vulnerabilities include bugs and overflows, these vulnerabilities allow attackers to execute code to perform (DoS) or steal information. Rooting out where vulnerabilities can exist will help integrators understand how and where to apply mitigations to prevent exploitation and neutralize attacks. HMIs display data from various sensors and machines connected to the SCADA system to help operators make decisions to implement using the same interface. Essential steps to be employed to industrial control networks include mapping out all your current systems, implementing monitoring and detections systems, and having security protocols. Harden the perimeter, restrict logical and physical access to the ICS network and monitor remote access solutions to prevent malware.
