Washington (QHA) - U.S. National Security Agency (NSA) intends to lay off 90% of its full-time system administrators and replace them with computers. Such measures are aimed to increase the safety level of NSA secret programs, reports dni.ru referring to the Agency’s director Keith Alexander. According to Alexander, thus the agency wants to reduce the number of people who have access to information. Not mentioning Edward Snowden’s case, Alexander stressed that work of security services is based on trust and people who don’t justify the trust may cause great damage to the country. According to Alexander, replacing one thousand of NSA system administrators with computers will make the network more stable and secure, reports Rosbalt. Earlier, the U.S. authorities said that the ex-intelligence officer Edward Snowden caused considerable damage to the U.S. security and accused him of leaking secret information. The White House has repeatedly called on Moscow to extradite Snowden, who was in the transit area of Sheremetyevo airport but couldn’t take off from there as his passport was invalidated. On August 2 it was reported that Snowden received temporary asylum in Russia. Because of that, Barack Obama canceled his meeting with Vladimir Putin in Moscow, which was scheduled for August 7.
