The AOC Office of Security Programs (OSP), led by Ken Eads, is responsible for the maintenance, care and operation of the buildings, grounds and security enhancements of the U.S. Capitol Police (USCP) and other related facilities. OSP is also responsible for centralized security operations. The AOC oversees and supports the USCP and other functions for policing, protecting and securing the congressional community and its visitors.

This office is responsible for the delivery of unique, value-added, integrated support services that include all cross-jurisdiction security enhancements, the management of all AOC internal security programs and perimeter security kiosks and the coordination of interagency emergency preparedness.
