Internet of Things (IoT) Security: How to Protect Your Smart Devices from Cyber Threats

Our lives are being transformed by the Internet of Things (IoT), which connects objects to the internet. Nowadays, IoT devices are growing in popularity, including smart thermostats, security cameras, wearable fitness trackers, and smart refrigerators. Although these devices are very useful and efficient, they also bring new difficulties and dangers, especially regarding security. As per the DSCI reports, the organisation has Over 400 million detections across approximately 8.5 million Endpoints. This article will cover IoT security and how to safeguard your smart devices from cyber threats.

Understanding IoT Security

IoT security refers to measures applied to safeguard IoT devices & the networks they are connected to from cyber threats. These threats include unauthorised access, data breaches, and cyberattacks that can compromise the functionality and privacy of the devices. The existence of billions of IoT devices in use makes the security of these devices a must to avoid possible damage to people and organisations.

The key Threats to IoT security

The main threats to IoT devices can be identified, which will result in the creation of strategies to ensure IoT security.

• Botnets

Hackers can hijack IoT devices to form botnets and launch large-scale attacks like DDoS.

• Data Breaches

Unauthorised access to IoT devices can cause data breaches, resulting from personal and sensitive information being compromised.

• Remote Control

Hackers have the ability to exploit IoT devices, seizing control and potentially causing physical damage or service disruption.

• Malware

Malware can infect IoT devices, which can either malfunction or become part of a bigger attack network. The way to shield smart devices from cyber threats is to be aware of the potential dangers and take the necessary precautions.

Protect Your Smart Devices From Cyber Threats

• Change Default Settings

One of the simplest yet most effective measures for connected devices protection is to alter the default usernames and passwords on your devices for IoT security. Make sure you use strong, unique passwords with letters, numbers, and special characters.

• Keep Software Updated

Check that your IoT devices are on the latest firmware and software. Manufacturers release new versions to remove connected devices’ protection and security weaknesses. Thus, regular updates are a must for the connected device’s protection.

• Employ a secure network to safeguard the data.

It is very important to link your IoT devices to the network security for IoT. The Wi-Fi network should be protected by strong encryption (WPA3 if available) and a unique, strong password. Please consider the possibility of creating a separate network for connected device protection and isolating them from other devices on your main network.

• Enable Two-Factor Authentication

The 2FA should be enabled whenever your IoT devices and related accounts can ensure network security for IoT. This improves security by introducing a second verification form, further strengthening the password.

• Disable Unused Features

Many IoT devices have features that you may not need. Turn off any unnecessary features to minimise the attack surface of your devices. For instance, if your smart camera has remote access that you don’t use, turn it off.

• Monitor Device Activity

Frequently check the activity of your IoT devices. Be on the lookout for any strange or unusual behaviour; for example, the sudden increase or decrease in data usage or performance. Many devices have apps that let you monitor their activity.

• Make use of Network Security Solutions.

Ensure the safety of your network with top-notch security solutions, like firewalls & intrusion detection systems. These steps can shield your whole network, including your IoT devices, from unauthorised access and attacks.

• Use IoT-Specific Security Solutions

Certain security organisations provide solutions, especially for Internet of Things devices. These technologies can identify and mitigate risks specific to IoT settings, offering enhanced protection.

Bottom Line

IoT device growth is bringing possibilities and difficulties. Although these gadgets might improve our quality of life, they also present new security threats. In 2017, consumers in India collectively lost over 18 billion U.S. dollars due to cyber crimes. IoT technology can help you reap its advantages while lowering its hazards if you understand it and take protective measures to secure your devices and network. To protect your linked devices from online dangers, always remember to modify default settings, keep your devices updated, utilise secure networks, and use best practices for network security.
