The TSA was formed under the Aviation and Transportation Security Act, on 2001 in the aftermath of 9/11. The TSA is focused on strengthening and protecting transportation systems. The TSA is focused mainly on air transportation and hires the screening officers in airports, armed Federal Air Marshals for planes (TSA, 2017). The agency also uses mobile teams of dogs for explosive detection. The TSA must work with other agencies such as Homeland Security and the FBI in order to detect threats and respond to security breaches. Collaboration is important to these agencies because the transportation, especially aviation is critical infrastructure that impacts other critical infrastructures by providing support for their ongoing operations.
