As the Internet of Things (IoT) thrives to transform industries and our lives, ensuring robust IoT security measures has become imperative. Securing IoT devices and protecting data privacy are essential considerations in this interconnected landscape of Internet Of Things systems. In this blog, we will explore key IoT security best practices and provide valuable tips for enhancing your IoT network security. By implementing these practices, you can safeguard your IoT devices, mitigate risks, and maintain the confidentiality and integrity of your valuable IoT data. So, Let’s delve into the world of IoT security and discover the best steps to fortify your IoT ecosystem.

Internet Of Things (IoT) – Introduction

The Internet of Things or IoT is defined as billions of devices connected around the world that are now connected to the Internet for collecting and sharing data. The idea of adding sensors and intelligence to devices and objects was discussed in the early 1980s and 1990s but devices were incapable of communicating effectively, and chips were too heavy and bulky. One of the Tech companies (IDC) predicts that there will be around 41.6 billion connected IoT devices or things by the year 2025.

The IoT connects physical things with digital information systems or the internet. Initially, IoT was most interesting to manufacturing and business, where sometimes its application is known as machine to machine(M2M), but now its significance is on filling our offices, homes, and societies with intelligent devices and transforming them into something useful and relevant for everyone.

Securing IoT Devices

Security in IoT devices is becoming increasingly important when it comes to the enormous scale or picture of cybersecurity, while cybersecurity seeks to protect our systems or appliances from cyber attacks. IoT security is all about securing devices connected over the internet. In IoT devices and hardware share or transfer the data without human involvement. A typical IoT system works by continuously sending, receiving, and analyzing data in a feedback loop. The biggest reason IoT security is so important because your smart devices or IoT devices can be used to gain unauthorized access to your systems. Most people might not realize that their device can be hacked, but it can. Because the potential attack surface grows with each IoT device you add to your network.

Risks And Challenges In IoT Devices

IoT devices were not developed with security in mind, as was previously discussed. In contrast to other technological solutions, IoT security is governed by various norms and laws because most people do not understand the inherent risks of their IoT system. There are numerous IoT security concerns, including the following:

• Limited security integration: It can be difficult or impossible to integrate all IoT devices into security systems due to their diversity and sheer volume.
• Weak passwords: IoT devices frequently come with default passwords that many users don’t update, making it simple for cybercriminals to access them. Other times, users generate passwords that are easily guessable and weak.
• Massive data volume: The amount of data generated by IoT devices make data failure, protection, and management difficult.
• Lack of visibility: IoT devices are frequently installed by users without the knowledge of IT departments, making it impossible to identify with accuracy what needs to be safeguarded and monitored.
• Open-source code vulnerabilities: IoT device firmware frequently uses open-source software, which can have faults and vulnerabilities.
• Vulnerable APIs: APIs are frequently utilized as entry points to attack command and control centers from which assaults like SQL injection, distributed denial of service (DDoS), man-in-the-middle (MITM), and network intrusion are launched.

How Can We Secure Our IoT Devices?

Securing IoT devices is crucial to protect against potential threats and vulnerabilities. Here are some essential steps to enhance the security of IoT devices:

•  Monitor Your Network
• Automate your response time
• Control Access 
• Use different passwords for each device and never stick with default passwords provided by IoT devices.
• Turn off Bluetooth or WiFi when connectivity is not needed.
• Keep your device up to date with the latest software and firmware.
• Put your IoT device on a separate network from your important system.
• And never assume that your IoT device is incapable of being hacked, so for this keep monitoring your device and use them with the latest software.

IoT Data Privacy

Privacy in IoT devices (IoT data privacy) is important because it protects our integrity and promotes trust in digital interactions and maintains the fundamental rights of individuals in a data-driven world. The rapid rise in IoT devices generates huge amounts of data about individuals and IoT devices can collect information like daily life activities and habits. The information that an IoT device can collect includes health-related data, consumption data, location data, and any other useful information we don’t want to share with any unauthorized users. 

We often accept companies ‘privacy policies in terms of purchasing and using the service of IoT or devices. These documents can authorize companies to use your personally identifiable data for their purposes and transfer or disclose certain data to third parties. And in IoT and data protection, there are various concerns like where is my data sent? , how is my data stored and used, and does anyone else have access to my data?

Things that keep us safe from data breaches and considered as best IoT data privacy practices:

1.  Use IoT data encryption

 Use an IoT encryption algorithm whether you’re using a symmetric key or an asymmetric key. This is the main step to keep your data safe and secure.

2. Secure Your Network

To protect your data from harmful cyber attacks we need to secure and protect the network that’s connecting various IoT devices.

3.  To make your network more secure you should include:

•  Antivirus
• Anti-malware
• Firewalls

4. Authenticate your IoT device

Using encryption keys to protect users and we should also allow users to authenticate IoT devices. Mechanisms to authenticate IoT devices are:

• Two-factor authentication
• Biometrics
• Digital signatures or certificates

5. Use up-to-date firmware and keep testing.

IoT Network Security Tips

The rise in IoT devices makes one’s life easier and more convenient as users or consumers have access to everything from smartphones to smart fridges, But before using their services we had to keep some points related to IoT network security tips in our mind to protect our network or device from cyber-attacks.

Some of the IoT Network Security tips are as follows:

• Customize Security Settings
• Set up a separate WI-Fi network
• Control your private cellular data
• Research before Buying
• Updated Firmware
• Learn about security certifications
• Set up two-factor authentication
• Reset password regularly
• Adopt micro-segmentation
• Read terms and conditions carefully
• Opt out from data sharing 

Conclusion

The rise in IoT improves the living conditions of an individual and benefits organizations and enterprises in many ways. However, IoT data privacy and personal data protection in the IoT space remain problematic. Regular Testing and updating can be implemented so that we can believe in a bright future for this technology.As mentioned above, use strong passwords, and don’t stick to default passwords. Always use antivirus software, Do not click on links in emails from unknown senders or unfamiliar websites. Avoid using unsecured WiFi networks in public places. Also, try not to open emails from unknown senders.
