Lockheed Martin Corp, the Pentagon''s No 1 supplier, is experiencing a major disruption to its computer systems that could be related to a problem with network security, two sources familiar with the issue said on Thursday. Lockheed, the biggest provider of information technology to the US government, is grappling with "major internal computer network problems," said one of the sources who was not authorised to publicly discuss the matter.
A second source, who also asked not to be identified, said the issue was "affecting a lot of people" at Lockheed, maker of the stealthy F-22 and F-35 fighter planes and other critical weapons systems. Lockheed, which employs 133,000 people world-wide and had $45.8 billion in revenues last year, said it did not discuss specific threats or responses as a matter of principle, but regularly took actions to counter threats and ensure security.
"We have policies and procedures in place to mitigate the cyber threats to our business, and we remain confident in the integrity of our robust, multilayered information systems security," said spokesman Jeffery Adams. Big corporations - especially government contractors - keep matters of internal security secret and rarely publicly disclose problems in securing their networks.
The sources said Lockheed employees were still able to use mobile devices to access their company email accounts. The slowdown began on Sunday after security experts for the company detected an intrusion to the network, according to technology blogger Robert Cringely. He said it involved the use of SecurID tokens that employees use to access Lockheed''s internal network from outside its firewall, A spokesman for EMC Corp, whose RSA division makes the tokens, declined to comment, saying it is company policy to never discuss security issues affecting specific customers.
