The White House is expected to reveal its next executive action on cybersecurity at the summit, which will bring together tech executives, leading academics and government officials to discuss ways in which the government can better collaborate with the private sector on cybersecurity initiatives.
Cook's remarks come at a time where law enforcement and tech companies are at a battle between privacy and security. Companies like Apple and Google have been strengthening their security with new encryption, making it more difficult for law enforcement to access data on devices.
Both the Department of Justice and the FBI have been opposed to the steps tech companies have been making towards increasing privacy and security of devices. FBI director James Comey has been looking for Congress to pass laws mandating that companies give the government access to data on devices through a "back door."
FBI Assistant Director Joe Demarest Jr. will also speak at Friday’s summit.
