“A Pentagon pilot program that uses classified National Security Agency data to protect the computer networks of defense contractors has had some success but also has failed to meet some expectations, according to a study commissioned by the Defense Department.
The program showed that Internet carriers could be trusted to handle the NSA data, that direct government monitoring of private networks could be avoided and that the measures could be of particular benefit to companies with less mature cyber defense capabilities, according to the Carnegie Mellon University study.”
