Beware of Cyber Threats! Here’s How to Secure Your IoT Devices Effectively

Jakarta, INTI - Internet of Things (IoT) devices have become an essential part of modern life. From smartphones and surveillance cameras to household appliances, IoT connects everything to the internet, making daily tasks easier. However, as these devices become more popular, they also attract a growing number of cyber threats that can compromise users’ privacy and security.

According to recent reports from global cybersecurity organizations, attacks on IoT devices have increased by up to 300% over the past three years. This rise in attacks is fueled by the growing number of IoT devices being used without adequate security measures. In this article, we’ll discuss practical steps to ensure your IoT devices remain secure against cyber threats.

1. Change Default Passwords on IoT Devices

The first step often overlooked by users is changing the default password on their IoT devices. Many IoT devices come with a factory-set password, which unfortunately is easy for hackers to find. With simple hacking techniques, hackers can gain access to devices by relying on these default passwords.

• Practical Tip: Change the password on your IoT device immediately after installation. Use a strong password with a combination of uppercase letters, lowercase letters, numbers, and symbols. Avoid using overly common or easily guessed passwords.

According to a 2023 security study, 60% of hacked IoT devices used a default or weak password. This highlights the importance of changing the default password as the first line of defense.

2. Keep IoT Devices Updated

Updating device software (firmware) is crucial for maintaining the security of IoT devices. Manufacturers often release updates that contain security patches and functionality improvements. Ignoring these updates can leave devices vulnerable to attacks.

• Practical Tip: Enable automatic updates if available. Otherwise, regularly check the manufacturer’s website or the device management app to ensure your device is always running the latest firmware.

In a survey by Cybersecurity Ventures, around 75% of cyber attacks on IoT devices were due to outdated firmware. Keeping devices updated can close security gaps that hackers might exploit.

3. Use a Secure Network

Many IoT users connect their devices to home Wi-Fi networks without encrypting the network or using a strong password. An unsecured connection is highly vulnerable to man-in-the-middle attacks, where hackers can intercept data being transmitted between IoT devices and the network.

• Practical Tip: Use WPA3 or at least WPA2 encryption on your Wi-Fi network and avoid using public Wi-Fi to access IoT devices. Additionally, separate IoT devices from your main network by using the guest network feature on modern routers.

Statistics from the National Institute of Standards and Technology (NIST) show that networks using WPA2 or WPA3 encryption are up to 90% more secure than networks with no encryption or outdated encryption methods.

4. Enable Two-Factor Authentication (2FA)

Two-factor authentication is an additional security layer that helps protect your IoT devices. With 2FA, users must enter an additional verification code, usually sent to another device, before accessing IoT devices.

• Practical Tip: Enable 2FA on your IoT devices or their management apps if the feature is available. This makes it harder for hackers to access your device even if they know the password.

In a 2022 study, two-factor authentication reduced the risk of cyber attacks on IoT devices by up to 50%.

5. Use Trusted Apps to Manage IoT Devices

Many IoT devices require an app for remote management. Users often download unofficial apps or use third-party software, which may have security vulnerabilities.

• Practical Tip: Use only the official apps provided by the device manufacturer and avoid untrusted third-party apps. Also, ensure that the app is regularly updated.

According to a report by McAfee Labs, untrusted third-party apps accounted for around 30% of cyber attacks on IoT devices, often due to malware embedded within these apps.

6. Limit Access to IoT Devices

Your IoT device may have options for multiple user access. To minimize risk, limit the number of people with access and only allow access to those who truly need it.

• Practical Tip: If your device allows, create guest accounts or provide limited access. Restrict access only to devices on the home network.

In many cases, uncontrolled access has been a primary cause of data breaches, especially with IoT devices used in work environments.

7. Implement Additional Security Measures, Such as a VPN

A Virtual Private Network (VPN) is an excellent solution for protecting data traffic on your home network, including data sent through IoT devices. By encrypting data, VPNs prevent hackers from monitoring and accessing your devices.

• Practical Tip: Use a trusted VPN service and avoid free VPNs, which often have weaker security. Make sure to enable the VPN on your router so that all connected devices, including IoT devices, are protected.

Studies show that using a VPN can reduce the risk of man-in-the-middle attacks by up to 70%, providing an extra layer of security for IoT devices.

8. Enable Monitoring and Alerts for Unusual Activity

Modern IoT devices often have monitoring and alert features that can identify unusual activity. By enabling these features, you will be notified if there are suspicious access attempts.

• Practical Tip: Check your device's security settings in its app and enable security notifications. With this feature, you can take action immediately if there is any suspicious activity.

According to a report from Symantec, monitoring activity on IoT devices can prevent up to 40% of attacks by providing early warnings to users.

9. Utilize AI Technology for Enhanced Security

Artificial Intelligence (AI) technology is increasingly being integrated into IoT devices to detect unusual patterns that may signal an attack. This technology allows devices to learn normal usage patterns and alert users when there’s suspicious activity.

• Practical Tip: Consider using IoT devices with AI-based security features, especially if you use them for business or sensitive data.

Data shows that IoT devices with AI-based security have a 30% higher threat detection rate than those without.

Securing your IoT devices is essential given the rising risks of cyber attacks. By following the steps above, you can ensure your IoT devices stay safe, and your privacy remains protected.
