Locking down the Internet of Things

WiFi security on the Internet of Things

Have you gotten all of your new tech gadgets hooked up after Christmas? Seems like every gift that had a plug also had a phone app and connected to Wi-Fi. Throughout the year as new toys or even appliances enter your home, setting up individual devices isn’t that noticeable. But after Christmas rolls through and you start setting up all the new goodies it really makes you sit back and notice-You have entered the new age of a smart home. Without realizing it we have created our own attachment to the Internet of Things (IoT).

That's a lot of things

Leichtman Research Group in 2018 found that 74% of U.S. homes had at least one smart device. Statista estimates that there will be 42.2 million smart homes in 2019. Spending on IoT devices was $23.3 billion (yes, billion) and is estimated to be $75 billion by 2025.  While there are Bluetooth connections, the primary connection for IoTs is Wi-Fi. Statista reported that the average number of connected devices per person, worldwide, in 2015 was 3.47 and is estimated to be 6.58 by 2020. That is connected devices per person. Multiply that by people in your home and the for-the-common-good devices like appliances, cameras, plugs, bulbs, etc, and that’s a lot of connectivity. 

If you want to keep up with technology it is how it’s going to be. I didn’t set out to convert the ol’ analog home to “smart”. It just happened. Garage door opener, a new appliance here and there, TVs, Hey Google, Hey Siri, Alexa, before you know it you’re your home is smart. The router sent me a message, yes it communicates as well, that the network was getting full. You’re aware of connectivity for your phones and computers but forget about the other electronics-appliances/TVs/cameras/power strips/gaming systems/eBooks, etc-that are on all the time and trying to communicate with the mother ship. Not only are these devices taxing on your home network they are all portals for security breaches.

Anyone of these connected devices can be hacked at the source, through the controlling app, or the company that provides the service. All the more reason to review your home network security.  If you haven’t done so recently, with the onset of all your new tech wonderness, you’ll need to upgrade your Internet service.  Most times these types of upgrades come with new routers. 

Security

One of the first actions you should take on all routers and new devices is set up your own logins and passwords. Many people still use the default settings, which cybercriminals are aware. Changing this information will at least slow them down. I say slow down because, as we’ve seen, anyone can be hacked. At least changing the settings will offer some protection.

For all of your connected devices actually, read the setup instructions and pay attention to what you are agreeing to during the process. Data collection is big business and those companies want your data. As consumers get more privacy savvy the product providers are finding counteractions. I recently loaded an app that wanted access to my phone’s camera, microphone, location, and to send user data. Answering no to any of those requests denied the user access. Or sometimes certain features are denied or dampened if the user doesn’t agree to the terms.

Devices that listen, your phone, TV, Echo, Google home, are also collecting data and have been proven to also be recording your conversations. In the interest of improving their service, of course. Again, go through the setup and privacy menus carefully. Understand what the device, i.e.-manufacturer is asking you to allow.

Overall, you have to understand that if you allow “smart” devices into your home you are giving up privacy. It’s hard not to get caught up in the technology craze, but understand that what you’re getting yourself into.

Are you being watched?

Do you feel safe in your home? Your exterior is probably pretty well defended against intruders with metal doors and deadbolts, locking windows, and maybe an alarm system. How about intruders from within?  “…The call is coming from inside the house”, an oft repeated quote from the 1979 movie, When a Stranger Calls, can still make your skin crawl when you’re all alone, think you heard a noise, and then the phone rings. Just the thought of an intruder with you in your home can be terrifying. There may not be physical intruders inside your home at this moment, but someone may be listening or quite possibly watching.

Internet of things

Kevin Ashton of Procter & Gamble first coined “Internet of things” in 1999. It is defined as network of devices, appliances, vehicles, etc. that connect and exchange data through the Internet. It is estimated the Internet of things will be populated with 30 billion devices by 2020.

Technology has always invaded our homes as we excitedly open the boxes to the latest modern conveniences. In the early days of the 1900’s telephones began appearing in homes. The 1950’s saw televisions showing up in living rooms. People started bringing home desktop computers in the 1980’s. Those computers were connected to the Internet in the 1990’s.  Phones went on our belts and into our pockets in the 2000’s and then became handheld computers. The first Internet connected appliance was a LG refrigerator released in 2000. According to Statista.com, there were nearly 36 million smart home devices sold in the U.S. in 2017. Over 40 million smart TV’s were sold in the U.S. in 2016 and 244 million worldwide.

Privacy

The remote accessibility of household devices creates new security issues everyday. As appliances get “smarter” their vulnerability also increases. Smart devices only work to their full capability if they are connected to the Internet. Once that occurs they are searchable and hackable. When the device reaches out to the web it declares itself open for business. Hackers are always looking for unsecure networks and devices to exploit. If not for gain then just because then can.

We first heard about these types of intrusions in 2015 two years after consumers starting bringing home smart TV’s.  Samsung released TV’s in 2013 that could listen to voice commands from their owners. The problem? The TV has to be listening all the time to pick up the commands. What was “heard” was being transmitted via the Internet. Samsung warned consumers, through privacy policies, that spoken words are being captured and transmitted through the voice recognition system. Consumers were further warned not to hold personal conversations in front of the television. But who read or reads the privacy policies, right?

Another popular device entering our homes are web accessible cameras. We set these up to watch the nanny, housekeeper, or house in general. There are even petcams available that not only allow owners to watch their pets but speak to them and deliver treats remotely. The first cameras imbedded in teddy bears, sold as a “nanny cams”, began appearing on the market in 1992. The first cameras to transmit remotely via IP were sold by Axis Communications in 1996. Today, the market is flooded with cameras and phone apps that allow web transmission of live video. It’s fun to watch Mr. Snugglekins romp around the house. But if you can access your webcam remotely, so can someone else.

Hacking

The device most people have heard stories about and are aware is the camera on your computer. Yes, they can be used against you. Unlike the movies, your home computer usually has to be “infected” with malware that you allowed in my clicking on a link or visiting a sketchy website. As with all of your devices, locally, you have to let someone in for them to be monitored. Not to say that you and your devices could not be specifically targeted and intruded. With the effort it could be done. Hackers and, yes, governments have the capability to access the television microphones, computer and remote cameras, turning them on and off and recording at will. However, most likely you’ve been the victim of malware.

The privacy and security issue with smart appliances is the collection and transmission of data. First, your viewing habits, conversations, actions are being collected. Second, the data is being transmitted to the Internet and held on third party servers. All of which can be hacked. So no matter the security measures you take at home, your personal data is vulnerable once it hits the WWW.

The thing is, you allow them into your home with the purchase, unpacking, and setup to connect to your network. Data transmissions you are unaware of because you have most likely allowed the device to set itself up per the manufacturer’s settings. Any warning or setup recommendations were clicked through and unread. Admit it. You’ve done it. Who reads the privacy settings on a new device? Or whenever you allow an update? That’s what the manufacturers are counting on. The key word in the previous paragraph is “allow”. You’re inviting the snooping by purchasing the device, bringing it into your home, and allowing self setup.

Your appliances aren’t the only ones listening. There’s been conspiracies floated the last couple of years that Facebook is listening to your conversations to better target ads. While feasible it is unlikely and has been debunked by several sources. Facebook may not be overhearing conversations but they, as is Google, “listening” by recording your search habits and even communications in messaging and emails apps to better address advertising. Netflix was recently caught by tweeting about the number of times a few viewers had watched one of its programs, trying to be funny. Netflix admitted that it did track viewing habits of subscribers.

Security

When you invite smart appliances into your home you give up your privacy. You have to consider these devices as other persons and guard your privacy accordingly. Take the time to read the manufacturer privacy policies. Read the manual setup instructions and adjust the device settings accordingly. Block cameras in sensitive areas or turn them towards the wall when you’re home.

This reads like an Orwellian or tinfoil hat conspiracy. It wasn’t meant to be or to keep you from enjoying the conveniences of technology. Just be aware of the surroundings you’ve created. Any smart device has to be considered to be listening or watching. Alexa, Siri, Google, they all have to be listening all the time to be able to pick up your commands.
