Resilience Engineering Flashcards
1
Q
Recognition strategy
A
- Detecting the symptoms of a problem that may lead to system failure
2
Q
Resistance strategy
A
- Invoking actions that reduce the probability that a system will fail after a problem of cyberattack has been detected
3
Q
Recovery strategy
A
- Critical services are restored as quickly as possible so that the consequences of a failure or cyberattack are minimized.
4
Q
Reinstatement strategy
A
- All system services are restored and the system brought back to normal operation.
5
Q
Cybersecurity
A
- Sociotechnical issue
- Protection of citizens
- Protection of businesses
- Protection of critical infrastructures
6
Q
Cybersecurity threats
A
- Threats to confidentiality of assets
- Threats to integrity of assets
- Threats to availability of assets
7
Q
Two approaches to human errors
A
- Person approach
- System approach
8
Q
Latent conditions
A
- Vulnerabilities and weaknesses in a system, that at some stage, may contribute to system failure
9
Q
Active failures
A
- Some operational event or human error that triggers a sequence of events that could lead to system failure
10
Q
Swiss cheese model
A
- Defensive layers have vulnerabilities.
- Vulnerabilities are dynamic.
- Failure occurs when holes line up.
11
Q
Operational processes
A
- Processes for using the system
- Important defense mechanism
12
Q
Coping with failures
A
- Design operational processes to be flexible and adaptable.
13
Q
Critical service identification
A
- Services that must always be available to a system to be usable
14
Q
Diverse barriers in a system
A
- Close holes and reduce the chance of holes lining up.
15
Q
Defensive layers
A
- Use redundancy and diversity to create a set of defensive layers.
