Francesca Sales: RSA Conference 2016: IoT will crash and burn if security doesn't come first

The message from RSA Conference 2016: Build security into IoT devices early on, or court disaster. Also in Searchlight: Apple gets a boost; a chance to 'hack the Pentagon.'

SAN FRANCISCO -- Gartner estimates 6.4 billion Internet-connected devices will be in use this year; by 2020, the number skyrockets to 21 billion. Unless the companies that make these interconnected devices overhaul their information security practices and incorporate them into development processes earlier, IoT will be DOA.
