U.S. Customs and Border Protection (CBP) implemented the Secure Electronic Network for Travelers Rapid Inspection Program in 1995, as a border management initiative to accelerate the inspection of pre-enrolled low-risk travelers at designated southern land border United States ports of entry. Participants voluntarily provide personally identifiable information to CBP, undergo background checks, and use dedicated lanes that allow CBP to maintain border integrity, security, and law enforcement responsibilities. However, some program members have abused their privileges and transported illicit goods across the border. Smugglers and drug traffickers have also targeted program participants as conduits for illegal cross-border activities. In addition, some CBP officers serving at ports of entry potentially pose an insider threat. As a result, effective internal controls are essential for the program to deter and detect illegal activity.
