SCADA for National Critical Infrastructures: Review of the Security Threats, Vulnerabilities and Countermeasures

The Supervisory Control And Data Acquisition (SCADA) networks contain computers and applications that perform key functions in providing essential services and commodities to citizens such as electricity, natural gas, crude oil and refined petroleum products, waste-water treatment and transportation. This paper looks at SCADA, its architecture and functions to industrial control system (ICS) as well its security threats, vulnerabilities and attacks that could prevent SCADA from delivering these functions especially in Nigeria. This paper finally recommended far-reaching holistic solutions to the various SCADA's security challenges.
