AIS appears to do a wide variety of things at a variety of locations within the US, including Baltimore. Their web site says they will be at a career fair at UMBC on 10/9:

"University of Maryland, Baltimore County (UMBC) Career Fair on October 9, 2013 from 11:30AM to 3:30PM at Retriever Activities Center (RAC)" from http://www.ainfosec.com/home/careers/

I imagine some of you will want to check them out.
