Also, the majority of travelers prefer to travel from the air rather than water. That’s why the main work of the TSA is to confirm the identity of the travelers coming from other countries and ensure that they are natural persons. Terrorists make a different number of passports and use many names for travel purposes. Therefore, this agency tracks such people if any of them enter the US. The work done by this organization is very confidential, and only higher officials of the administration get the details from TSA.

Earlier the work of the security was done by the department of transportation established in the United States. But after multiple failures of the transportation department to control the attacks, the government decided to form an agency solely for security. Also, different states had different transportation officials, so the process was not much synchronized. But with the introduction of a central agency to look after the security of the travelers, the entire process became highly synchronized, and hence the security was tightened many folds.
