Week 02: Risk and Resilience Flashcards
What are 4 factors for increased risk to CI?
- Increasing demands
- Aging Infrastructure
- Interconnected and Interdependent Nature
- Increasing attractiveness of CI as a target.
Who defines Resilience as:
“… the capacity of a system, community or society exposed to hazards to adapt to disturbances resulting from hazards by persevering, recuperating or changing to reach and maintain an acceptable level of functioning.”
Emergency Management Framework for Canada
What are the Core Elements of Resilience? (4)
- Robustness
- Redundancy
- Resourcefulness
- Rapidity
“… the inherent strength or resistance in a system to withstand external demands without degradation or loss of functionality.” What is this the definition of?
a. Robustness
b. Redundancy
c. Resourcefulness
d. Rapidity
a. Robustness
“System properties that allow for alternate options, choices, and substitutions under stress.” What is this the definition of?
a. Robustness
b. Redundancy
c. Resourcefulness
d. Rapidity
b. Redundancy
“The capacity to mobilize needed resources and services in an emergency” What is this the definition of?
a. Robustness
b. Redundancy
c. Resourcefulness
d. Rapidity
c. Resourcefulness
“The speed with which disruption can be overcome and safety, services, and financial stability restored.” What is this the definition of?
a. Robustness
b. Redundancy
c. Resourcefulness
d. Rapidity
d. Rapidity
Other conditions for resiliency in CI include what capacities/considerations? (3)
- Absorptive capacity
- Adaptive capacity
- Restorative capacity
What are the four dimensions of resilience?
- Technical
- Organizational
- Social
- Economic
What is the technical dimension of resilience? (4)
- Physical properties of infrastructure
- Components, systems, networks
- How these behave with regard to CI Impacts
- Important for engineering resilience
What is the organizational dimension of resilience? (3)
- The organizations and institutions that manage the physical components of the system
- CI owners/operators
- How does/do the culture, people, risk management, respond to threats/disruption at the organizational level
What is the social dimension of resilience? (2)
- Population and community characteristics that make the population more or less vulnerable to impacts
- CI is central to the functioning of society
What is the economic dimension of resilience? (3)
- Potentially high costs of protection
- Protective measures alone may not be enough
- Resilience more broadly then becomes necessary
What is the National Strategy for Critical Infrastructure’s three keys to resilience?
- Build partnerships to support and enhance CI resiliency
- Implement all-hazards risk management approach
- Advance the timely sharing and protection of information among partners and key stakeholder
What are the three overall CI resiliency objectives?
- Minimize damage to CI during the event
- Maintain operational integrity and critical services immediately following the event
- Return to normal, safe operating conditions as soon as possible
Why would dependencies and interdependencies matter in CI? (3)
- Protection and resiliency demand an understanding of dependency
- The relationships are often complex, and non-obvious
- The interconnected nature of CI can and has led to cascading failures (including cross-sectoral and transnational).
Dependency leads to a more accurate assessment of criticality of what two things?
- Of a component
- Of a whole sector
“A bidirectional relationship between two infrastructures through which the state of each infrastructure influences or is correlated to the state of the other.”
Is this the definition of interdependency or dependency?
Interdependency
“A linkage or connection between two infrastructures through which the state of one infrastructure influences or is correlated to the state of the other.”
Is this the definition of interdependency or dependency?
Dependency
What are the four classifications of Interdependency and Dependency?
- Physical interdependency
- Cyber (inter)dependency
- Geographical (inter)dependency
- Logical (inter)dependency
True or False:
“The more dependencies, the more critical…, the more vulnerable, the more critical…, and the lack of alternatives increases its criticality.”
TRUE
What are three types of dependence-related disruptions?
- Cascading
- Escalating
- Common-cause
What is the difference between cascade initiating and cascade resulting failures?
Initiating is an event that causes another event in another CI, while resulting is an event that results from an event in another CI.
Which two sectors are the main cascading initiating sectors?
Energy and Telecommunications
