Brazilian state-controlled oil and gas giant Petrobras on Monday evening issued a statement on the possible surveillance of its networks by U.S. National Security Agency (NSA), saying it has highly secure, updated systems to protect its internal network.
News came to light in a TV program Sunday night that documents leaked by former NSA contractor Edward Snowden show that Petrobras was targeted by the NSA espionage scheme.
Petrobras said in the Monday statement that the communication between the internal and external networks is permanently monitored.
"For example, an average 90 percent of external e-mail messages received by Petrobras are discarded for preventing potentially damaging content," the company stated, adding that its employees are trained to understand the importance of correctly handling information and that sensitive information is encrypted compatible with its required protection levels.
As threats become more complex, the investments on technology to protect data will increase over time, the company said, adding Petrobras' investments in information technology and telecommunications are compatible with its Business Plan.
Earlier Monday, Brazilian President Dilma Rousseff issued an official statement especially on the latest news that NSA spied on Petrobras, demanding again explanations from the U.S. government.
Rousseff said if the latest news are indeed proven, they will confirm that the U.S. motivation has nothing to do with self- protection, but everything to do with economic and strategic interests.
"Petrobras does not represent a threat to the security of any country. It represents, however, one of the world's largest oil assets and a patrimony of the Brazilian people," said Rousseff.
She said her administration has already demanded explanations from the U.S. government on the violations and also demanded concrete actions to end what she claimed as "espionage offensive to human rights, Brazil's sovereignty and economic interests."
