WASHINGTON — Early last year, as Edward Snowden was preparing to disclose classified documents he had purloined from National Security Agency computers in Hawaii, the NSA director, Gen. Keith Alexander, was gearing up to sell Congress and the public on a proposal for the NSA to defend private U.S. computer networks against cyber attacks.
Alexander wanted to use the NSA's powerful tools to scan Internet traffic for malicious software code. He said the NSA could kill the viruses and other digital threats without reading consumers' private emails, texts and Web searches.
The NSA normally protects military and other national security computer networks. Alexander also wanted authority to prevent hackers from penetrating U.S. banks, defense industries, telecommunications systems and other institutions to crash their networks or to steal intellectual property worth billions of dollars.

FOR THE RECORD:
National Security Agency: An article in the Feb. 2 Section A on the effects of Edward Snowden's leaks of National Security Agency secrets said the White House backed the Cyber Intelligence Sharing and Protection Act, a cybersecurity measure. The White House threatened to veto the proposed bill in April. —
But after Snowden, a contractor, began leaking NSA systems for spying in cyberspace that went public in June, Alexander's proposal was a political nonstarter, felled by distrust of his agency's fearsome surveillance powers in the seesawing national debate over privacy and national security.
