These are links to the two Surveillance Detection books that I know of. One of the authors, Laura Clark, is an old friend; she has attended the VDI Surveillance Detection Program. I would recommend her book. Also the old Scotti School put together an SD Manual for a Federal Agency, the manual (the parts that are applicable to the private sector) is used in the VDI SD program. ISDA Advisory Board member, Joe Autera has used his corporate experience to add to the VDI manual. Also the ISDA Resource Center has a number of articles concerning SD and parts of the Federal Manual.
