This paper reviews the state of the art in cyber security risk assessment of Supervisory Control and Data Acquisition (SCADA) systems.

We select and in-detail examine twenty-four risk assessment methods developed for or applied in the context of a SCADA system.

Initially, SCADA systems were used in power transmission, gas pipeline and water distribution control systems.

Nowadays, SCADA systems are widely used in steel making, chemistry, telecommunications, experimental and manufacturing facilities (Daneels, Salter, 1999; Igure , 2006 ; Morgan, 2013).

You'll learn theories combined with real-world applications and practical skills you can apply on the job right away. You must complete each course with a grade of B or better to advance to the next course. The courses in this program will have seven-day and 60-day options for the grade of Incomplete.

This program is designed to help prepare cyber security technology leaders who can develop mission-focused digital strategy for organizations.

These will give you a foundation that will help you succeed in the program.

Leveraging the skills and tool set of our cybersecurity experts, trained to stay actively informed of the rapidly changing landscape of security threats and compliance requirements, the cybersecurity services which are available through our service packages are designed to help safeguard your operational integrity. Pre-test security updates are deployed onto your radio network system to address known vulnerabilities as soon as they are available and validated to avoid network disruption. Our team of experienced security professionals remotely monitor your system for our Security Operations Center (SOC) for security events and apply countermeasures whenever necessary. If remote security monitoring is not a viable option for you, our On-Premise Security Operations Center provides you with a reliable means to proactively monitor your network for unusual security activities. Using industry standards and frameworks, we perform a comprehensive risk assessment to help you understand your risk posture and steps that should be taken to mitigate, react, and respond to cyber threats based on your unique operational requirements.

Our penetration testing service involves an active analysis of the asset for any potential security vulnerability.

This could result from poor or improper configuration, both known and unknown hardware or software flaws, and operational weaknesses in process or technical countermeasures.

We describe the essence of the methods and then analyse them in terms of aim; application domain; the stages of risk management addressed; key risk management concepts covered; impact measurement; sources of probabilistic data; evaluation and tool support.

Based on the analysis, we suggest an intuitive scheme for the categorisation of cyber security risk assessment methods for SCADA systems.
