Janet Napolitano, the secretary of the Department of Homeland Security, is at Boston City Hall this afternoon, nearing the end of a two-day visit that has taken her to a Cambridge fire house, a naturalization ceremony at Faneuil Hall, and to Logan Airport.

Napolitano attended a swearing-in ceremony at Faneuil Hall for about 410 naturalized citizens from dozens of countries. She then went across the street to City Hall, where she is expected to meet with Mayor Menino.

Earlier today, she was in Cambridge meeting with college and university presidents to discuss new courses and majors aimed at preparing graduates to enter the field of cybersecurity.

She also stopped by the Cambridge Fire Department headquarters to thank local firefighters, EMTs, and paramedics for their service.

This afternoon, Napolitano huddled with Boston Police Commissioner Edward Davis at the Area A-1 station in Government Center.

On Thursday, Napolitano was in East Boston where she said 60 more explosives detection units will be installed at Logan.
