Crabb has guided multiple teams in support of the U.S. Postal Service Computer Incident Response Team, other law enforcement agencies and the intelligence community, including the Department of Justice’s Computer Crime and Intellectual Property Section. He initiated and led the Inspection Service’s coordination with Carnegie Mellon’s Software Engineering Institute, and has worked with the Resilience Management Program to improve the security of the U.S. Mail.
