The Internet has changed since the terrorist attacks of Sept. 11, 2001 — perhaps enough that the cybersecurity of Apple's iPhones is a top economic priority, one high-ranking Bush-era official said.
"I think everybody agrees that where the government has a lawful order they ought to be able to get everything that is available," former U.S. Homeland Security Secretary Michael Chertoff told CNBC's "Closing Bell" on Monday.
"But the Internet has changed. The vulnerabilities are greater. The threats to innocent people are greater. And if people are going to continue to transact business over the Internet, they have to believe it's not going to be interfered with," said Chertoff.
