U.S. Border Security
The concept of border security in the United States shares a complex relationship with the persistent threat of terrorism. Border security includes the protection of land borders, ports, and airports. The relationship is unique in the sense that the federal government must constantly reevaluate and tweak its border security policy to address the perceived threats posed to the United States through the form of human terrorism or the smuggling and detonation of a weapon of mass destruction. Historical context Immediately after the events of September 11, 2001, the Federal Government placed a higher priority on homeland security, such as intelligence reform. Following 9/11 incident, the border security apparatuses were heavily scrutinized and were the target of public criticism. Moreover, border security issues drew additional public criticism and from senior officials in the government after it was known that 9/11 hijackers held temporary U.S tourist visa, meaning they gained l ...

Border Security
Border control refers to measures taken by governments to monitor and regulate the movement of people, animals, and goods across land, air, and maritime borders. While border control is typically associated with international borders, it also encompasses controls imposed on internal borders within a single state. Border control measures serve a variety of purposes, ranging from enforcing customs, sanitary and phytosanitary, or biosecurity regulations to restricting migration. While some borders (including most states' internal borders and international borders within the Schengen Area) are open and completely unguarded, others (including the vast majority of borders between countries as well as some internal borders) are subject to some degree of control and may be crossed legally only at designated checkpoints. Border controls in the 21st century are tightly intertwined with intricate systems of travel documents, visas, and increasingly complex policies that vary bet ...

CompStat
CompStat—or COMPSTAT, short for COMPuter STATistics, is a computerization and quantification program used by police departments. It was originally set up by the New York City Police Department in the 1990s. Variations of the program have since been used in police departments across the world. According to a 2022 podcast by Peter Moskos with John Yohe and Billy Gorta, the name CompStat was suggested by detective Richard Mahere for the computer file name of the original program to comply with 8.3 filename conventions, short for "COMParative STATistics" and "COMPuter STATistics". Origins CompStat was started under the direction of Jack Maple when he was a transit police officer in New York City. The system was called Charts of the Future and was simple – it tracked crime through pins stuck in maps. Charts of the Future is credited with cutting subway crime by 27 percent. The original commanding officer of the Transit Police Crime Analysis Unit was Lieutenant Richard Vasconi. Chie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Body Scanner
A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Unlike metal detectors, full-body scanners can detect non-metal objects, which became an increasing concern after various airliner bombing attempts in the 2000s and some scanners can also detect swallowed items or hidden in body cavities of a person. Starting in 2007, full-body scanners started supplementing metal detectors at airports and train stations in many countries. Three distinct technologies have been used in practice: * ''Millimeter wave scanners'' use non-ionizing electromagnetic radiation similar to that used by wireless data transmitters, in the extremely high frequency (EHF) radio band (which is a lower frequency than visible light). The health risks posed by these machines are still being studied, and the evidence is mixed, though millimeter wave scanners do not generate ionizing radi ...

Federal Air Marshals
The Federal Air Marshal Service (FAMS) is a United States federal law enforcement agency under the supervision of the Transportation Security Administration (TSA) of the United States Department of Homeland Security (DHS). Because of the nature of their occupation, federal air marshals (FAMs) travel often. They must also train to be highly proficient marksmen. A FAM's job is to blend in with other passengers on board aircraft and rely heavily on their training, including investigative techniques, criminal terrorist behavior recognition, firearms proficiency, aircraft-specific tactics, and close quarters self-defense measures to protect the flying public. History In 1961, Gen. Benjamin O. Davis Jr., presented the idea of armed security forces on commercial flights. President John F. Kennedy ordered federal law enforcement officers to be deployed to act as security officers on certain high-risk flights. The Federal Air Marshal Service began on March 2, 1962 as the Federal Aviati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
No Fly List
The No Fly List maintained by the United States federal government's Terrorist Screening Center (TSC) is one of several lists included in algorithmic rulesets used by government agencies and airlines to decide who to allow to board airline flights. The TSC's No Fly List is a list of people who are prohibited from boarding commercial aircraft for travel within, into, or out of the United States. This list has also been used to divert aircraft away from U.S. airspace that do not have start- or end-point destinations within the United States. The number of people on the list rises and falls according to threat and intelligence reporting. There were 16,000 names on the list in 2011, in 2012, and in 2013. The list—along with the Secondary Security Screening Selection, which tags would-be passengers for extra inspection—was created after the September 11 attacks of 2001. The No Fly List, the Selectee List, and the Terrorist Watch List were created by George W. Bush's adminis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Security Screening Selection
Secondary Security Screening Selection or Secondary Security Screening Selectee, known by its initials SSSS, is an airport security measure in the United States which selects passengers for additional inspection. People from certain countries are subject to it by default. The passengers may be known as Selectee, Automatic Selectee or the Selectee list. The number of names on the list fluctuates and is a secret, although the Transportation Security Administration apparently says there are tens of thousands of names on it. The Selectee list has been cited by civil liberties groups to be infringing on privacy rights and potential for racial and ethnic discrimination. Procedure when selected Passengers who have been selected for secondary screening will have the letters ''SSSS'' or ''*S*'' (all capitals) printed on their boarding passes as a signal for the need for a thorough search at security checkpoints. In the case of Southwest Airlines, secondary screening selectees may ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation Security Administration
The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within, and connecting to the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a dedicated federal administrative law enforcement agency. The TSA develops broad policies to protect the U.S. transportation system, including highways, railroads, buses, mass transit systems, ports, pipelines, and intermodal freight facilities. It fulfills this mission in conjunction with other federal agencies and state partners. However, the TSA's primary focus is on airport security and the prevention of aircraft hijacking. It is responsible for screening passengers and baggage at more than 450 U.S. airports, employing screening officers in airports, armed Federal Air Marshals on planes, mobile teams of dog ...

Aviation And Transportation Security Act
The Aviation and Transportation Security Act (ATSA, November 19, 2001) was enacted by the 107th United States Congress in the immediate aftermath of the September 11, 2001 attacks. The Act created the Transportation Security Administration (TSA). However, with the passage of the Homeland Security Act The Homeland Security Act (HSA) of 2002, () was introduced in the aftermath of the September 11 attacks and subsequent mailings of anthrax spores. The HSA was cosponsored by 118 members of Congress. The act passed the U.S. Senate by a vote of ... in 2002, the TSA was later transferred to the Department of Homeland Security. The legislation (S. 1447) was sponsored by Democratic Senator Fritz Hollings from South Carolina and co-sponsored by 30 other senators. Prior to ATSA, passenger screening was the responsibility of airlines, with the actual duties of operating the screening checkpoint contracted-out to private firms such as Wackenhut, Globe, and ITS.

Automated Targeting System
The Automated Targeting System or ATS is a United States Department of Homeland Security computerized system that, for every person who crosses U.S. borders, scrutinizes a large volume of data related to that person (see below), and then automatically assigns a rating for which the expectation is that it helps gauge whether this person may be placed within a risk group of terrorists or other criminals. Similarly ATS analyzes data related to container cargo. These ratings take many details into account, such as country of origin, how travel to the U.S. was funded, and the visitor's driving record. Other more mundane details also factor in, such as where the person is sitting on the flight and what they ordered for their meal. The existence of such a system was first discovered by the public in November 2006, when a mention of it appeared in the Federal Register. The system was first implemented in the late 1990s, and was significantly expanded shortly after the 9/11 Terrorist Attack ...

Port Authority
In Canada and the United States, a port authority (less commonly a port district) is a governmental or quasi-governmental public authority for a special-purpose district usually formed by a legislative body (or bodies) to operate ports and other transportation infrastructure. In Canada, the federal Minister of Transport selects the local chief executive board member and the rest of the board is appointed at the recommendation of port users to the federal Minister; while all Canadian port authorities have a federal or Crown charter called ''Letters Patent''. Numerous Caribbean nations have port authorities, including those of Aruba, British Virgin Islands, Bahamas, Jamaica, Cayman Islands, Trinidad and Tobago, St. Lucia, St. Maarten, St. Vincent and the Grenadines. Central and South America also have port agencies such as ''autoridad'' and ''consorcio'' (authority and consortium). In Mexico, the federal government created sixteen port administrations in 1994–1995 called ''Adm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defense In Depth
Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack to lose momentum over time or as it covers a larger area. A defender can thus yield lightly defended territory in an effort to stress an attacker's logistics or spread out a numerically superior attacking force. Once an attacker has lost momentum or is forced to spread out to pacify a large area, defensive counter-attacks can be mounted on the attacker's weak points, with the goal being to cause attrition or drive the attacker back to its original starting position. Strategy A conventional defence strategy would concentrate all military resources at a front line, which, if breached by an attacker, would leave the remaining defenders i ...
