As the usage of the internet of Things (IoT) continue to become ubiquitous, it is becoming more important to protect these devices from various security threats. Default security settings of devices are often low, if they even exist, meaning that it’s imperative for users to take the necessary steps to secure their devices and networks. Without an effective security plan, it is easy for hackers to take over and exploit a vulnerable device for malicious activities. Therefore, it is important for users to understand ways to improve IoT security to get maximum protection for their device networks.
What Is IoT?
The Internet of Things (IoT) is a network of physical objects connected to the internet that enable the exchange and generation of data. Examples of connected physical objects include mundane household items such as thermostats, lighting systems and home appliances, through to more advanced items such as autonomous vehicles and industrial machinery.
The key feature of the IoT is that it makes everyday life easier and more efficient. For example, a person can use their smartphone to remotely control their heating and cooling system at home, meaning that the house will always be at a comfortable temperature, no matter where the person is.
Simple Ways to Improve IoT Security
When it comes to securing an IoT network, there are many simple steps that can be taken in order to ensure maximum protection. The following is a list of some of the best ways to improve IoT security:
-
Use unique passwords: When setting up a device or creating an account, it is important to create passwords that are not easy to guess. Try to include a combination of numbers, upper and lowercase letters, and special characters. It is also important to change passwords regularly and use different passwords for each device or account.
-
Update devices regularly: Security flaws and vulnerabilities can be discovered in devices over time, and therefore, it is important to keep devices up-to-date with the latest firmware and software updates. Most devices come with automatic updates enabled, but it is wise to double-check periodically.
-
Keep a separate network for IoT devices: IoT devices should be kept on a separate network from other devices. This will help to compartmentalize the devices, meaning that if one device gets hacked, it will not impact the other devices.
-
Enable two-factor authentication: Two-factor authentication is an extra layer of security that requires the user to authenticate themselves twice before accessing a device or system. This greatly reduces the likelihood of a hacker gaining access to a device or system.
-
Use encryption: Encryption is a great way to protect data that is sent or stored on devices. It is also important to choose devices that support the latest encryption protocols in order to maintain the highest level of security.
-
Disable remote access: Most devices come with remote access enabled by default. This means that hackers can gain access to the devices by exploiting security vulnerabilities. Therefore, it is important to disable remote access and only enable it when it is absolutely necessary.
-
Monitor devices: By monitoring devices, users can identify any suspicious activities that may indicate a security breach. It is also important to monitor log activity for unusual activities such as sudden spikes in traffic.
-
Use VPNs: A virtual private network (VPN) is a great way to secure the transmission of data between devices. A VPN will encrypt all data sent over the internet, meaning that hackers will not be able to intercept the data.
-
Utilize firewalls: Firewalls are an essential tool for controlling the flow of traffic between devices and networks. It is important to configure the firewall so that only authorized users and devices can access the network.
Securing an IoT network can be a formidable task, but it is not impossible. By following the simple steps outlined above, users can improve their device’s security and ensure that their sensitive data is safe from malicious activities. It is also important to remember to periodically review security settings and update devices with the latest firmware and software in order to ensure maximum protection. Taking the necessary steps to secure an IoT network is essential for users to avoid the potential security risks associated with these devices.
