## Highlights

The Secure Border Initiative (SBI) is intended to help secure the 6,000 miles of international borders that the contiguous United States shares with Canada and Mexico. The program, which began in November 2005, seeks to enhance border security and reduce illegal immigration by improving surveillance technologies, raising staffing levels, increasing domestic enforcement of immigration laws, and improving physical infrastructure along the nation's borders. Within SBI, the Secure Border Initiative Network (SBInet) is a multibillion dollar program that includes the acquisition, development, integration, deployment, and operation of surveillance technologies--such as unattended ground sensors and radar and cameras mounted on fixed and mobile towers--to create a "virtual border fence." In addition, command, control, communications, and intelligence (C3I) software and hardware are to use the information gathered by the surveillance technologies to create a real-time picture of what is transpiring within specific areas along the border and transmit the information to command centers and vehicles.
