Network security analysis SCADA system automation on industrial process

Supervisory Control and Data Acquisition (SCADA) is a unit control system that has been used almost in various industries around the world in terms of process automation. This system delineates the real infrastructure and provides ease in operations and monitoring, but this system has vulnerability in the security aspects of data communications connected between SCADA support devices. This can have a major impact on industry and the economy. This research was conducted by designing and building SCADA infrastructure and analyzing vulnerability threats to SCADA network security. This research penetrates SCADA network using Kali Linux and data traffic analysis on SCADA network using Wireshark. From the results of Wireshark analysis got the attacker with User Anonymous. Analysis performed with normal and abnormal data traffic conditions. The result of this research is penetration of SCADA network using Kali Linux, which is used to attack and make data traffic between Programable Logic Controller (PLC) with Human Machine Interface (HMI) becomes solid, and result from penetration testing, SCADA system become down due of data traffic on a dense network, thereby indicating that SCADA networks are vulnerable to malware threats and attacks, the results of this study are recommendations and network security strategy SCADA system.
