So your "smart home" is online. What could possibly go wrong? Well, if your security is weak, crooks can enter your home using their smart phones.

Lots of us are buying smart thermostats and automated door locks. But Texas cyber security expert Keith Squires says if you can control it remotely, so can crooks.

"Once you put something on a network where someone can get to it, including yourself, then security becomes an issue."

Parents like the control automated door locks bring.

"Some parents may want the ability to ensure that when the kids come home from school the door is locked. So they put one of these electronic locks on there and they can check it from work and make sure the door is locked."

But Squires says you need to make sure you understand how to secure your smart home.

"The worst case scenario is someone's got a door lock or a garage door enabled and you go by and open the door."

Squires says the message isn't to stop using these devices, but use a secure password and some kind of secondary authentication, if possible.
