Eric O'Neill, the former FBI operative who played a crucial role in the arrest and conviction of FBI agent Robert Hanssen for spying against the U.S. for the former Soviet Union and Russia, says security can't rely on tech alone.

Anyone who has worked to defend enterprise secrets from theft knows that the answer to success certainly doesn't come from technology alone.

Few know this better than Eric O'Neill. O'Neill is the former FBI operative who worked as an investigative specialist and played a crucial role in the arrest and conviction of FBI agent Robert Hanssen for spying against the U.S. for the former Soviet Union and Russia. The 2007 movie "Breach" was based on O'Neill's experience investigating Hanssen.

"The human element is usually the weakest link," O'Neill said yesterday at the 2011 Computer Enterprise and Investigations Conference (CEIC) 2011.
