IoT (Internet of Things) devices bring incredible convenience and functionality, but they also come with risks since they are connected to the Internet, which opens the door to potential threats. To protect your data, privacy, and devices, it is essential to understand and implement the following steps that will help you secure your assets.
1. Change default passwords
Many devices (cameras, printers, thermostats) come with default passwords (or even no passwords), which are easy to guess. Hackers often scan networks for devices with default settings that can be easily taken over. There are even services online, such as shodan.io, where you can search for such devices yourself. After the first setup of your device, go to its administrative settings and immediately change the password to something more complex.
2. Regular software updates
Manufacturers constantly examine their software and release updates to fix bugs and security vulnerabilities. Ignoring these updates can leave your device vulnerable to attacks. Hackers can exploit known vulnerabilities in older software versions to gain control over the device. Regular updates are a crucial step in reducing the risk of an attack.
3. Network segmentation
Network segmentation involves dividing your network into different segments to minimize the risk associated with a potential attack. If one of your devices gets hacked, network segmentation prevents the hacker from accessing more sensitive parts of your network, such as computers containing company data. Many routers offer the option to create a separate network for IoT devices or a separate Wi-Fi network for guests.
4. Disable unused features and ports
IoT devices often come with additional features that aren’t always necessary but can pose potential security risks. Features like remote access and Bluetooth communication can be potential attack vectors. If you don’t use these features, disable them. Devices may also have open ports that aren’t needed for daily operation. These can be exploited by attackers to gain access to your devices. Deactivating unnecessary ports reduces the attack surface.
5. Create backups
Creating backups is an important step that can facilitate quick system recovery after an attack or failure. If a device becomes infected or compromised, a backup allows you to quickly restore the original settings without the need to reconfigure from scratch.
6. Use trusted products
Not all devices are designed with security in mind. Choosing reputable and trusted brands can significantly reduce risks. Renowned companies typically invest more in security measures and provide regular updates for their products. By selecting trusted brands, you gain confidence that the manufacturer prioritizes user security.
