HALIFAX - The world's leading military minds gathered in Halifax to talk about terrorism, freedom and technology this weekend, while a terrorist organization taunted them all online.

On Saturday, the head of the United States National Security Agency (NSA) sat next to Canadian Justice Minister and forum founder Peter MacKay, and Jane Harman, head of Woodrow Wilson International Center for Scholars.

"The world is becoming an incredible network of sensors," Admiral Mike Rogers, director of the NSA said, explaining the amount of cameras, microphones and other technology in place around the world.

Rogers said the free world's greatest challenge in fighting borderless "death cults" like ISIS and other terrorist groups is balancing surveillance and civil liberties.

"The risk, the threat, has never been greater and the trust in our own governments as never been lower."
