We find smart devices at work, at home, everywhere in general. Considering that these devices are so integrated into our lives, ensuring their secure use is essential.
The Internet of Things (IoT) expands every day, but so do the security threats. Vulnerabilities can be found in the network that connects IoT devices, or result in unauthorized access to devices or the theft of data.
It doesn’t matter whether you want to secure your home device or devices based on Linux VPS plans, protecting the IoT environment is still very important.
Let’s explore how you can ensure the security of your IoT devices.
Why Is Cybersecurity in IoT Essential?
Internet of Things (IoT) implies devices and objects that are all connected to the Internet, and with each other for smooth data transmission. However, relying on this cycle with no intermediary alone won’t help shield your devices from potential security threats.
The statistic shows that more than 90% of traffic going through IoT devices is unencrypted, which means that sensitive data is exposed to potential threats. Cybersecurity risks are especially amplified in IoT infrastructure since the devices and systems are interconnected, which means that access to one device can grant you access to the whole network.
Considering the vast integration of IoT devices in many vital sectors such as healthcare, public transportation, and homes, it is paramount to ensure the cybersecurity of the digital environment to avoid unwanted consequences.
Key Vulnerabilities of IoT Devices
Here are some widespread vulnerabilities of IoT devices to pay attention to:
- Outdated firmware and software. Users don’t usually update the firmware or software on IoT devices after their deployment, which makes them more susceptible to security threats.
- Weak or default passwords. IoT devices often come with default passwords that offer poor protection; if they aren’t changed, they may become a vulnerability that could be exploited.
- Poor testing. Many IoT devices aren’t properly tested for vulnerabilities because the functionality is more prioritized.
- Limited options for security integration. There are many types of IoT devices, and most of them don’t support integration with security frameworks right out of the box, while some aren’t compatible with common security systems at all.
- Complex ecosystems. Environments where IoT technology is integrated usually consist of multiple devices and protocols, which require a unique approach to cybersecurity.
- Big data volumes. IoT devices often transfer large amounts of data through the network, which can complicate the systems processing the data.
- Insufficient encryption. Data transferred through unencrypted channels, which is a frequent case with IoT devices, can easily be compromised and stolen.
Therefore, insufficient IoT security can turn out to be a liability if not handled correctly. Consequences such as reputational damage and legal complications are a possible result of weakened cybersecurity.
However, there are ways that can help you strengthen IoT cybersecurity.
How to Secure Your Devices
IoT devices have always been attractive targets for cybercriminals, so it is important to know how to strengthen their security.
Implement Strong Passwords
Passwords might seem like a minor thing, but they’re able to sufficiently protect your device if they are strong.
Password-related attacks on IoT devices are pretty common. Therefore, after your device has been connected to the network, it’s better to reset the default password with a more complex one.
Update Firmware
One cannot eliminate vulnerabilities in IoT devices with simple updates. Since these devices have a long shelf life, which often leads to discontinued support, it is recommended to download security patches straight from the vendor’s website when first setting up the device.
You can even explore if the vendor offers regular patch upgrades and management.
Practice Network Segmentation
The goal of network segmentation is to reduce the impact of potential attacks. The principle here is to divide the network into several sections, which you’ll be able to control independently.
In a continuous network where endpoints are directly linked to one another, there’s a bigger risk of an attack spreading across the whole network, affecting all devices involved.
Monitor IoT Devices
Even if you’ve set up the security measures on your devices, once they’re deployed, real-time monitoring is required. This activity includes tracking performance, arising issues, and responding to irregularities.
Monitoring the device’s behavior is one of the best ways to spot weak spots and vulnerabilities that can be overlooked during the setup.
