Lecture 6 Flashcards
Perhaps security has stopped more routine accidents, however, accidents teach awareness of _______.
An example?
Vulnerability
When the Minneapolis, Minn. I-35W bridge fell into the Mississippi River during rush hour. The analyses of the incident highlighted the vulnerability to a bridge being stressed beyond it capabilities
______ and _____ for failure to anticipate, protect, and do a better job cleaning up.
An example?
Recrimination
blame
FEMA after hurricane Katrina
What are the 5 network simulations?
Bombing - reduce arc capacity on randomly selected arcs within the network
Terrorist attack - a few pre-selected arcs incurred significant damage
Flood - capacities of multiple connected arcs were reduced
Earthquake - randomly selected over a large area and their capacities were randomly reduced
Intermodal terminal attack - rail service inoperable in and out of CHI and LAX
Benefits of connection can become the __________. An example would be ?
Liability
Atlanta’s transport hub
It is clear that the importance of network infrastructure __________ is largely dependent on the location of its links and nodes, as well as their _________
Resilience
Connectivity
________ provide a test case for traffic gridlock.
An example would be?
Storms
I-285 of the Atlanta metro area
Use change in ________ ________ as an indicator of the consequences of dangerous events
Travel times
Topological relationships
How networks are connected
______ _______ provides simulation
Severe weather
Security has ________ more routine, ordinary accidents
Prevented
_________ teach us an awareness of vulnerability
Accidents
3 facts about security at Ports of LA/Long Beach…
5th busiest port in the world
Port security is complex due to the several municipalities that overlook it
Ships over 40% of the nations containerized cargo
4 facts about the security of PANYNJ….
Complex and aging infrastructure
Nation’s #1 international trade platform
Regional multi-state coordination challenges
(Port authority spans across 2 states)
PATH (railway system is also under this authority)
Hazard
An example?….
Something that can cause harm, e.g. electricity, chemicals, working up a ladder, noise, a keyboard, a bully at work, stress, etc.
Train carrying chlorine derailed near 5th Ave in Columbus. Osu issued a warning alert for a 2-3mi area because the substance was toxic
Risk
The chance, high or low, that any hazard will actually cause somebody harm.
“Train Wreck Prompts Renewed Effort on Chemical Shipment Security”
Where did this occur and what other questions did this incident propose?
Another example….
In PA where the train was carrying propane and hydrogen fluoride
How bad the fatalities and damage would be if terrorists attacked a liquified natural gas vessel?
A Quebec rail car derailed and a runaway train nearly demolished a town
Percolation (term used in physics(
To break a network up into small bits
Network Redundancy
Networks always work because of the positive attribute of redundancy that gives you backup plans
Networks grow by _____ _______
Selective or preferential attachment
Non Lethal Damage
3 examples….
Strategic disruption of transportation - mischief
Strikes of airport baggage handlers, burning tires across the road in Brazil, blocking major arteries with trucks in France
Simulation:
reduce arc capacity on randomly selected arcs within the network
Bombing
Simulation:
a few pre-selected arcs incurred significant damage
Terrorist attack
Simulation:
randomly selected over a large area and their capacities were randomly reduced
Earthquake
Simulation:
capacities of multiple connected arcs were reduced
Flood
