Abstract

The increasing demand of supervisory control systems connected remotely to critical
infrastructure and recently the internet, has profiled a high threat level to the security and function of
control system; more especially Supervisory Control and Data Acquisition (SCADA) systems. It is
very crucial that operators and management are knowledgeable about these threats and get familiarize
with ways to trace and track information required mitigating the threats. In present day very
competitive markets and with high levels of infrastructural investments, it is of vital importance for
corporations to be up-to-date with their SCADA networks so as to meet the challenges faced by
remote and/or mobile access, use and cyber threat posed to the critical systems infrastructures. We
have examined the security implications of having the SCADA system exposed to the mobile and/or
internet environment. The paper deals with the following issues: Section one looks at types of
infrastructures and the general functionalities of SCADA and assesses the risks in mobile
environment. The second section employs some of the recent methodologies applied to the SCADA
system. Section three reports on some findings from analysis and critically evaluates the risks posed
to the system using an augmented vulnerability tree approach. The last section draws from the
findings to re-evaluate, conclude and proposes some solutions on the risk issues of operating SCADA
in a mobile networked environment.
