Cyber security risk assessment for SCADA and DCS networks

The growing dependence of critical infrastructures and industrial automation on interconnected physical and cyber-based control systems has resulted in a growing and previously unforeseen cyber security threat to supervisory control and data acquisition (SCADA) and distributed control systems (DCSs). It is critical that engineers and managers understand these issues and know how to locate the information they need. This paper provides a broad overview of cyber security and risk assessment for SCADA and DCS, introduces the main industry organizations and government groups working in this area, and gives a comprehensive review of the literature to date. Major concepts related to the risk assessment methods are introduced with references cited for more detail. Included are risk assessment methods such as HHM, IIM, and RFRM which have been applied successfully to SCADA systems with many interdependencies and have highlighted the need for quantifiable metrics. Presented in broad terms is probability risk analysis (PRA) which includes methods such as FTA, ETA, and FEMA. The paper concludes with a general discussion of two recent methods (one based on compromise graphs and one on augmented vulnerability trees) that quantitatively determine the probability of an attack, the impact of the attack, and the reduction in risk associated with a particular countermeasure.

Understanding Ransomware and Strategies to Defeat it

whitePaper | March 5, 2020

Held Hostage in Hollywood: In February 2016 the Hollywood Presbyterian Medical Center, in Los Angeles, paid a ransom of about US$17,000 to hackers who infiltrated and disabled its computer network with ransomware. The hospital paid the ransom of 40 Bitcoins (currently worth about $16,664) after a “network infiltration” began on February 5, when employees reported being unable to access the hospital’s network and electronic medical records system. “The malware locked access to certain computer systems and prevented us from sharing communications electronically,” said hospital CEO Allen Stefanek.

Network Traffic Analysis (NTA): A Cybersecurity ‘Quick Win’

whitePaper | February 27, 2020

According to research from ESG and the Information Systems Security Association (ISSA), 91% of cybersecurity professionals believe that most organizations are either extremely or somewhat vulnerable to a significant cyber-attack or data breach.1 This level of cyber-risk demands immediate attention and action from CISOs, CIOs, and business executives. As a result, 62% of organizations plan to increase cybersecurity spending in 2020.2 Here’s the problem: Increasing security budgets alone isn’t enough. CISOs need quick and easy wins that can greatly bolster security efficacy and streamline operations without demanding massive projects and vast resources. There is a lot of work ahead. This white paper concludes.
