intro Flashcards
Vulnerabities
- everything has them
- there is a chanse they will be exploited
Risk (danger)
- unintenional exident
- safety
risk (threat)
- intentional
- security
core elements risk
- change that soming is gonna happen
- there is a future
- we can intervene
subway uncertainty
○ Bell curve
○ It is predictable
○ Probabilistic mathematics
○ Gets you a good idea of what you can aspect
Coconut uncertainty
○ Events that are super rare but have disastrous consequences
○ You cannot do math on it
○ You can’t predict it
is known unkown the only risk
yes
elementary risk
risk made by nature and war
man made risk
risk that are created becouse we wanted to solve a other risk
realism (risk)
technological
economic
psychometrics
risk are real
measurable
manageable
weak constructivism (risk)
Social + cultural risk society
risk are real but we understand them culturallly
strong constructivism
postmodern perspecitves
theres no such thing as a real risk risk is purely social cunstruct
barrier
someting that prevent or make the impact less of a unwanted consequentste
(barrier) Eleminate
maak de corodile af
move the target out of reach
loop weg van de krokodil
add a pasive barrier (barriers)
doe een hek om de krokodil
pasive barrier
- Passive barrier has a safety function in it mere existence
- helm
add an active barrier (barriers )
steek hem met een speer
active barrier
- Active barrier becomes activated when there is a particular problem
- Sprinkler
Prevention control
lowering that it can happen
Mitigation control
lowering the impact of a problem
- Event trees
○ Like dominions
○ If one thing goes down the rest also goes down
○ It tries to trace the outcomes incident –> outcomes
○ Always left to right
○ You can also in clue probability
○ Critical path : most likely
- Fault tree
○ Going from outcomes looking at wat went wrong
○ Used to chard root causes
○ From bottom to the top
○ Circle = basic event root cause
○ Diamond = Undeveloped event = root cause but we don’t have enough data
○ Square = intermediate event
○ Bell shape = logic gate
