Remember when refrigerators, air conditioners, and toasters did not have internet connectivity? This is no longer the case, and you can thank the Internet of Things the next time your refrigerator pings your phone when its power goes out, or your air conditioner begins blasting cold air into your living room ten minutes before you arrive home from work.
The Internet of Things, or IoT, is merely a network of Wi-Fi-enabled appliances and other gadgets that are all connected to the internet. The objective is to build a smart home consisting of internet-connected gadgets that can be remotely controlled from a smartphone or other device.
And the happy news? IoT is not as futuristic as it may appear. There are already a number of internet-connected appliances available for purchase from retailers, and the number continues to increase daily.
How Do IoT Devices Work?
Smartphones play a crucial part in the IoT since many IoT devices can be controlled via an app on a smartphone. For instance, you can use your smartphone to communicate with your smart thermostat to establish the ideal temperature before you arrive home from work. Another benefit? This can avoid unnecessary heating or cooling while you are away, so potentially reducing your energy expenditure.
IoT devices feature sensors and minicomputer processors that respond to machine learning-collected data. Because IoT devices are microscopic computers connected to the internet, they are susceptible to viruses and hackers. We’ll discuss IoT security in further detail later.
Machine learning is when computers acquire data from their surroundings and learn in a manner comparable to that of humans. It is what gives IoT devices intelligence. This information can assist the machine in learning your preferences and adapting accordingly. Machine learning is an artificial intelligence technique that enables computers to learn without being explicitly programmed.
This does not imply that your smart speaker will discuss the game’s critical moments with you. However, your connected refrigerator may send you a notification on your smartphone when it detects that you are running low on eggs and milk and is close to a grocery store.
IoT Security Risks
The Internet of Things and smart home technology can make living easier. As smart appliances and devices connect to the internet, however, there are IoT security issues associated with the creation of a linked house. They also save information regarding your choices. These devices contain vulnerabilities that hackers can use to discover the user’s preferences. They may even take control of your devices in order to spy on you.
Do you own a Google Nest or an Amazon Echo device? If you have ever exchanged passwords, credit card information, or bank account numbers with these digital assistants, a skilled hacker may be able to steal them.
Through one of your connected devices, hackers may gain access to your IoT network and infect it with ransomware. They can then lock you out of your computers, television, smart thermostat, and other devices until you pay a huge ransom, typically in bitcoin. They may even use a pet camera to spy on you or access your automatic lighting systems to determine when you are away from home.
How To Boost IoT Security?
There are actions you may do to improve the security of the Internet of Things.
- Don’t delay in approving security enhancements: Those pop-up messages requesting that you authorize device upgrades might be bothersome. However, they are also essential. Ensure that you accept these updates. Frequently, they are meant to protect your connected devices, such as your smart TV and programmable thermostat, from the most recent viruses and spyware.
- You may believe that your smart doorbell does not require a difficult password. But it does. Weak passwords can be cracked by hackers, granting them access to your devices and any personal or financial data stored on them. Create robust passwords that include numbers, characters, and symbols for all of your linked devices.
- Keep your router updated as well: Remember that your router is the core of your IoT network. Assign a strong password. Additionally, authorize any security updates for it. The gadgets linked to your router could be taken over by hackers who gain access to it.
- Enable two-factor authentication for IoT device logins if the option is available. In this procedure, you will initially provide a password and user name to log into an internet-connected device. The device then sends a code to your phone or email address. This code is required to complete the login process. Two-factor authentication requires an additional step during login, but it makes it far more difficult for thieves to access your devices.
