HSE 614 Discussion 4: Elements of Risk Management in Protecting Critical Infrastructure (Energy and Water Sectors)
Discuss the elements of risk management in relation to the protection of critical infrastructure. Select two critical infrastructure sectors and identify and discuss similarities in the elements of assessing risk for each. Within those sectors, identify specific assets in your community and explain the interdependencies between them.

Risk management for critical infrastructure follows the framework in the National Infrastructure Protection Plan (NIPP): set goals, identify infrastructure, assess and analyze risks, implement risk management activities and measure effectiveness (U.S. Department of Homeland Security [DHS], 2013). Risk is assessed as a function of three elements: threat (the likelihood that a hazard or adversary will act), vulnerability (weaknesses that could be exploited or damaged) and consequence (the effects on life, the economy, public health and national security) (DHS, 2013).
I selected the Energy and Water and Wastewater Systems sectors. Their risk assessments are similar in several ways. Both face all-hazards threats, including severe weather, physical attacks and cyberattacks on industrial control systems. Both have vulnerabilities in aging equipment, remote unmanned facilities and operational technology that is increasingly connected to networks. Both also carry extremely high consequences because almost every other sector depends on them, so analysts measure consequences in terms of population served and the duration of disruption, not only property damage.
In my community, key energy assets include [the regional electric substation that feeds downtown], [the natural gas pipeline gate station] and [the local power plant]. Key water assets include [the municipal water treatment plant], [booster pump stations] and [the wastewater treatment facility]. These assets are interdependent: the water treatment plant and pump stations need electricity to treat and move water, so a substation failure could leave neighborhoods without safe drinking water unless backup generators work. In turn, the power plant needs water for cooling, and the community’s hospitals and fire departments depend on both. A single event, such as an ice storm that downs power lines, could therefore cascade from the energy sector into water service and then into public health. Understanding these links helps planners prioritize backup power at pump stations and coordinate restoration between utilities.

Tip: name real assets, but describe them in general terms; avoid posting sensitive security details about specific facilities.
Frequently asked questions
What are the three elements of risk?
Threat, vulnerability and consequence.
What is an interdependency?
A two-way relationship in which each infrastructure depends on the other, such as water pumps needing electricity and power plants needing water for cooling.
