The current status of the Internet of Things (IoT) is discussed using the following quote: “With great power comes great responsibility.” As more devices are allowed to enter our homes and offices and transmit and receive sensitive information, cybersecurity becomes more important.
In 2021, the number of globally connected devices increased by 9% to 12.3 million. Security experts are concerned by the rapid adoption and acceleration of connected devices. Each year, there are 1.5 billion attacks on IoT devices. An ecosystem that has many connected devices is at risk if one device is infiltrated.
In the next few years, it should be a priority to implement and update security measures. Let’s take a look at six ways to secure IoT devices.
6 Ways To Secure IoT Devices
1. Improve Password Practices
Sometimes, the simplest methods can be the most efficient. Brute force techniques are surprisingly effective for hackers, for example. Brute force, an attack technique that attempts to automatically get the correct password by repeatedly trying until it succeeds, is called brute force.
This problem can be solved by ensuring that passwords are used correctly throughout the project. Use techniques like:
- When the object is first booted, change default passwords immediately
- Avoid using easily guessed passwords such as “12345”, a birth date, “admin,” or “password,”
- Combinations of numbers, letters, and symbols can be incorporated into your passwords
- Use different passwords for each device.
- Use a password manager
- Public Key Cryptography is a better alternative to using a password
2. To Encrypt Data when Connected to The Internet, Use a VPN
Data interception can be a problem when you send information via the internet. A VPN with encryption can help make your data safer.
Encrypting data is the process of taking plaintext and turning it into an encrypted text, usually using a randomly generated key. The information is encrypted at one end, then sent over the internet, and finally deciphered at the other.
This means that even hackers could not access your information. Encryption is an excellent tool to protect your data’s integrity and security.
A virtual private network (VPN), can be used to change your internet protocol address (IP). When a point-to-point connection is established using tunneling protocols, a VPN is created. This means that the IP address of your project – which is the number that identifies any device in a network’s location – can be changed to reflect the VPN.
3. Preparation for Scalability and Future Commissioning
You should be prepared for any unexpected vulnerabilities when adding new devices to an existing IoT project.
Any nearby networks will see any new device you add to an existing project. Imagine that you don’t take privacy and security in IoT seriously enough to add these devices to your project. Hackers could use these vulnerabilities to gain access to your entire project.
Use strategies to ensure that there are no open ports and that the connection is not made public for a prolonged period of time. A decentralized IoT Application Enablement Platform is a way to scale up your IoT projects. Decentralized AEP solutions allow you to scale up to make yourself more accessible, reduce security risks, and have minimal impact on communication speed.
4. Switch to a decentralized IoT platform
A decentralized IoT platform is a better security option than an IoT cloud platform. Cloud platforms can put data at risk as they send it via the internet to external databases that could be intercepted and breached. This could leave you completely out of control. All of this can happen while simultaneously compromising aspects such as latency, which makes it more expensive.
A decentralized AEP uses peer-to-peer technology (P2P), to communicate between devices. The IoT device is where data is stored, not in the cloud using P2P technology. Communication takes place directly, which reduces latency.
This method provides security by giving users full control over data on the network. Furthermore, encryption greatly reduces the risk of data being intercepted.

5. Segment your project
Segmentation is the process of dividing your network into several subnetworks. Segmentation can increase performance and make your project safer.
This is so that hackers can only access one subnetwork in your project. The rest of the subnetworks remain unaffected. This will allow you to shut down the compromised subnetwork, and the rest of your project can continue working as normal.
6. Keep your updates up to date
Last but not the least, be aware of any updates for your IoT devices. Manufacturer updates are usually used to fix bugs or improve security by fixing newly discovered vulnerabilities.
Don’t forget to keep up with any new updates for your IoT devices. Manufacturers often release updates that fix bugs and enhance security by patching up newly discovered vulnerabilities.
The widespread adoption of IoT devices has led to a growing awareness among the public about cybersecurity concerns. With new regulations looming, businesses around the world are reviewing their security strategies to protect their digital assets and devices.
These tips will help you to make your project more secure in the future. But remember, security and attacks change constantly. It is important to keep up with the latest developments and to regularly update security measures.
