Spy agency ducks questions about 'back doors' in tech products

The U.S. National Security Agency is rebuffing efforts by a leading Congressional critic to determine whether it is continuing to place so-called back doors into commercial technology products, in a controversial practice that critics say damages both U.S. industry and national security.

The NSA has long sought agreements with technology companies under which they would build special access for the spy agency into their products, according to disclosures by former NSA contractor Edward Snowden and reporting by Reuters and others.

These so-called back doors enable the NSA and other agencies to scan large amounts of traffic without a warrant. Agency advocates say the practice has eased collection of vital intelligence in other countries, including interception of terrorist communications.

The agency developed new rules for such practices after the Snowden leaks in order to reduce the chances of exposure and compromise, three former intelligence officials told Reuters. But aides to Senator Ron Wyden, a leading Democrat on the Senate Intelligence Committee, say the NSA has stonewalled on providing even the gist of the new guidelines.
