7 basic security tips in IoT

Aug 15, 201946

By 2017, Gartner estimated that there would be 8.4 billion Internet Stuff (IoT) devices in use - a 30 percent jump from 2016. But all of this advanced, integrated technology leaves room for potential security threats such as hackers and malware. If you use a smart device, increase your safety with these 7 IoT safety tips.

 

1. Know what is connected


Mobile devices
Before you can protect your devices, you need to know what is vulnerable to an attack. In Brazilian households, there are an average of five connected devices, including computers, tablets and smartphones. Watch the connected devices in your home - including game consoles, media players, and anything with a microphone or camera - and check the information each has access to.

 

2. Password protection for all devices and accounts

 

This is super basic, but it's always worth remembering! Every smart device you manage must be protected with a strong username and password that includes a combination of letters, numbers, and symbols. Avoid using the same password for multiple accounts. Otherwise, if a hacker can log in, he will have access to multiple devices.

 

3. Avoid using insecure Internet connections

 

When you check your smart devices remotely, do not use any Wi-Fi that is not password protected. Unsafe connections can make your device vulnerable to attack. To increase your personal network security, create strong passwords for your router and Wi-Fi connections and update them regularly.

 

Another important issue is to identify whether the digital environment of the site you are accessing is secure, check out our posts on How to identify if a digital environment is secure? and Shopping on the internet.

 

Keep operating systems, software, and applications always up-to-date
Often companies that develop operating systems, software or applications, provide up-to-date versions that present possible vulnerability fixes. The guideline is to always keep all smartphone apps, desktops, smart TVs, thermostats, and more up to date. This will help protect devices from ransomware attacks and other malware.

5. Create a separate network for your devices

 

Many routers allow you to configure multiple networks. Consult your router's manual to create at least one separate network for your IoT devices. The more secure your networks are, the harder it will be for hackers to hack into your devices and information.

 

6. Disconnect devices when not in use

 

Turn-Off
Turn off all devices when not in use, particularly those with microphones and camcorders. While some connected devices, such as smart thermostats, require a constant connection to the Internet, other devices - including smart TVs, coffee makers, and video cameras - do not. Prevent a hacker from connecting to your video or audio streams by disconnecting when you can.

 

7. Do not rush and be cautious

 

Frank Spano, executive director of The Counterterrorism Institute, says that moderation is needed when it comes to adopting IoT because it presents a wealth of personal information, financial data, and other confidential information. The technology is incredible, and we are really living in the future, but over-reliance on technology is a surefire recipe for disaster. So be cautious. The main cause of security breaches remains user neglect. It is necessary to educate users about usage policies. Having a clear understanding of potential vulnerabilities and limiting the accessibility of control within the network is of the utmost importance in limiting and avoiding intentional sabotage.

 

The Internet of Things allows you to improve your day to day business and simplify your life. But we still do not have full understanding or standards about the ability of hackers, that is, we do not have control over the internet. Basically, we are still in the process of creating internet technologies. So take the time to increase the security of your devices as well. By taking precautions in advance, you can help prevent malicious attacks.
