What does national security encompass?
Physical safety, economics, political stability domestically and internationally.
Includes military, diplomatic, economic, intelligence aspects.
What is the primary focus of homeland security?
Protecting the U.S. from threats within its borders.
Scope includes terrorism, natural disasters, and other domestic emergencies.
What key incidents influenced detection technology development?
- WWI - WWII
- 1960s civil unrest
- 1960s/70s plane hijackings
- Lockerbie Bombing (1988)
- Oklahoma City Bombing (1995)
- 9/11 attacks
- Shoe Bomber (2001)
- Liquid Bomb Plot (2006)
- Opioid crisis
Each incident led to advancements in security measures and detection technology.
What was a significant development in airport security in 1970?
New Orleans airport became the first to use metal detectors.
This marked the beginning of formal airport security measures.
What did the Air Transportation Security Act of 1974 require?
Metal detectors and X-ray screening of carry-on bags at all U.S. airports.
It was a response to hijacking threats.
What was the impact of the 1988 Lockerbie bombing?
U.S. carriers abroad required to x-ray or search all checked baggage and match passengers to their baggage.
This incident highlighted the need for more stringent security measures.
What was the Oklahoma City bombing’s effect on national security?
Underscored the need for a national strategy to prevent terrorist attacks.
Contributed to the creation of the Department of Homeland Security (DHS).
True or False: The 1993 World Trade Center bombing was dismissed as an isolated incident.
True.
This incident signaled U.S. vulnerability to terrorism.
What did the Gilmore Commission recommend in 2000?
Develop a coherent national strategy for combating terrorism.
Suggested the next President present this strategy to Congress within one year.
What were the limitations of detection infrastructure before 9/11?
Security responsibilities were fragmented, and detection capabilities were limited to basic systems.
Included X-ray systems, handheld metal detectors, and limited trace detection.
What is explosive trace detection?
A method using early ion mobility spectrometry (IMS) for rapid screening of hazardous materials.
Ideal for fast screening with high sensitivity.
What was the significance of canine detection programs in the 1970s?
Expansion of police work, agriculture detection, and narcotics detection.
Led to the establishment of national explosives detection canine teams.
What was the focus of port security during the Cold War?
Preventing smuggling of nuclear materials.
Radiation detection technologies like Geiger counters were utilized.
What challenges did the 9/11 attacks reveal about national security?
- Intelligence failures
- Lack of communication between intelligence agencies
- Aviation security issues
- Border security vulnerabilities
Highlighted the need for better preparedness and coordination.
What did the USA PATRIOT Act expand?
Government’s intelligence-gathering tools and ability to detain immigrants suspected of terrorism.
Passed in October 2001 following the 9/11 attacks.
What was established by the Homeland Security Act of 2002?
The Department of Homeland Security (DHS).
Merged 22 agencies into one department.
What are the current directorates of the DHS?
- National Protection and Programs
- Management
- Science and Technology
These focus on various aspects of security, including physical and virtual threats.
What did the President’s Commission on Critical Infrastructure recommend?
Widespread deployment of existing technology and additional research efforts.
Emphasized the need for a coordinated approach to infrastructure protection.
What were the challenges for R&D in homeland security prior to 9/11?
R&D resources were separated from homeland-defense missions, requiring collaborative research.
Needed integration across various fields and sectors.
In which fields does a viable system of sensors occur?
Chemistry, biology, physics, information technology
Sensors are crucial for monitoring and detection across various domains.
Which agencies support the development of sensor systems?
NSF, DARPA, DOE
These agencies play significant roles in funding and research.
What are the primary sectors involved in sensor system development?
Universities, national laboratories, industry
Collaboration across these sectors enhances innovation.
What is the ultimate goal of deploying sensor systems?
To be an element in an integrated security system
Integration is key for effective security.
What types of targets are considered diverse in terrorist threats?
Infrastructure, crowds, electric power grid, transportation
These targets require varied detection strategies.
