Critical Infrastructure to protect against Cyber Risk



A single point of failure (SPOF) is a part of an operation, that if it were to fail, could bring the entire operation to a halt or cause severe impact to other connected operations or society more broadly. SPOF exist in many operations and include hardware, software, mechanical infrastructure, assets, and key entities in supply chains. In most cases SPOF will impact the operation of the business itself such as the Southwest Airlines outage in 2016, where a single router failure caused the grounding of hundreds of the company’s flights over several days. Cyberattacks against critical infrastructure can take many forms including DDoS attacks, ransomware attacks, destructive malware attacks and unauthorized access to industrial control systems or hardware.



The increasing use of internet connected sensors, automated controls and remote access in critical infrastructure operations has inevitably led to a higher risk of cyberattacks aimed at these operations. However, the beginning of an alarming trend can be traced back to an attack that took place more than a decade ago. There were many historic critical infrastructure outages caused by natural catastrophe or system failure are at least somewhat useful in determining the consequences of cyberattacks on such infrastructure. Electricity is in itself very critical infrastructure, but all other critical infrastructure is also dependent on the power grid including water supply, energy supply, communication, transportation, healthcare, and banking. Finally, because cyberattacks are an entirely man-made threat, as opposed to the risks from natural hazards, motivation is an important factor in determining the probability of successful attacks.
