A smart home makes life more comfortable. But if it is not sufficiently protected, hackers can take control of your devices and spy on your private data. Hence the interest in thinking about security in order to be able to protect yourself from it. The connected home makes everyday devices smart. That is, you can control your surveillance camera or your heating remotely from your smartphone, or you can have a home equipped with lamps whose brightness automatically decreases.
How is it possible ? Just because sensors collect information about the environment, compare it to previous programming, and trigger action. But it also has dangers. Because lamps, heaters or cameras are connected to the Internet. The same risks apply to them as to all computers, tablets and smartphones that are online. If they are not protected, unauthorized persons can access them. Many networked devices have massive vulnerabilities and endanger the security of the home network, especially since they are constantly connected.
A connected home without any mode of protection
It sounds crazy and futuristic, but it can happen: you have a connected thermostat and window in your home. Then a hacker could have fun reprogramming your thermostat so that it tells your window to open. Then, nothing could be easier than breaking into your home. Or more simply: you have a connected lock and it is not protected. So any hacker can break into your home as easily as possible. Ultimately, every connected object is a potential way for unwanted people to enter your home. The real problem with connected objects is that in order to perform their intelligent functions, they need to be constantly connected to the internet, that is to say connected to a server or to the cloud. In addition, manufacturers are not bound by security standards, nor to guarantee compliance with certain requirements, such as encrypted data transmission. It is therefore possible that your smart camera is using an insecure password. If a hacker wants to gain access, all they need to do is try a list of standard passwords. Once he has access to the device, all he has to do is modify the software so that it can reload programs and respond to his commands. It also happens that some providers stop delivering updates after a short period of time. So one day you end up with software that is several years old and has never been updated.
And which can therefore have serious security vulnerabilities. In doing so, they create a breach in the security of your network.
Who is exposed to what threats?
Hackers rarely target a particular home. Rather, it is about targeting a set of people using the same technology. The principle is to overload a server so as to paralyze the operation of the system. Up to potentially hampering the infrastructure of entire countries.
How can you secure your connected home?
But what can you do to better protect your smart home from these dangers?
- Secure your internet network.
- Install firewalls.
- Equip your items with efficient antiviruses.
- Buy from a reputable manufacturer because they have a reputation to uphold and do not want to be linked to a possible scandal.
- Never integrate your devices connected to the same WLAN network as your other devices such as PC, laptop or mobile phone.
- Change the default password when you start using a connected object.
- Never use the same password on all devices.
- If manufacturers provide security updates, install them promptly. Or set up your objects so that they update automatically.
- While you’re on vacation, if you think your outdoor smart lights can deter thieves, consider this relevant if your mailbox isn’t overflowing with mail.
