I had the opportunity to participate in the DHS S&T Cyber Security Division Principal Investigators' Meeting in Washington D.C., September 16th thru 18th. The meeting had over 200 attendees, including researchers working in a wide range of research topics: Digital Provenance, Software Assurance, Security Metrics, Identity Management, Insider Threat, Cyber Forensics, Usable Security, and Network Mapping & Measurement.
