Obama is addressing cybersecurity following a massive hack of US government employees' personnel files, described as the most significant cyberattack in US history.
Obama says part of the problem is the US has very old systems for detecting intrusions. He says the US is upgrading old systems agency by agency to ensure that technology is up to date.
But Obama says the problem isn't going away. He says both governments and individuals are "throwing everything they've got" at US systems. Obama says that's why the U.S. Must be much more attentive to cybersecurity.
