How IoT is Impacting Network Security

The Internet of Things (IoT) has revolutionized the way we interact with technology, bringing added convenience and efficiency to our homes. However, as more devices become connected to our networks, network security concerns have arisen. In this article, we will explore how IoT impacts network security and provide tips for securing your smart home devices.

How IoT is Impacting Network Security

Understanding IoT Devices

IoT devices are any physical object that can be connected to the internet and can communicate with other devices on a network. Examples include smart thermostats, security cameras, door locks, and even light bulbs. These devices collect data from their environment through sensors or input from users and then transmit that data over the internet for analysis.

While these devices bring many benefits such as remote access and control of your home appliances, they also pose security risks as they become an entry point into your home network.

Security Risks Associated with IoT Devices

Due to their connectivity to the internet, any unsecured or compromised IoT device could allow hackers easy access to all other connected devices on the same network. This means that if one device gets hacked or becomes infected by malware or viruses; it could spread throughout your entire network leaving you vulnerable.


  • Unsecured firmware updates: Some manufacturers may not update their firmware regularly which means vulnerabilities go untouched.
  • Weak authentication protocols: Many IoT devices come standard with weak passwords making them prime targets for brute-force attacks.
  • Lack of encryption: Data in transit isn’t always secured by encryption leading to privacy risks.

Securing Your Smart Home Devices

Here are some top tips for protecting yourself against hacking threats when using smart home technology:

  1. Change Default Passwords – Always change default usernames/passwords set up by manufacturers immediately after installing new smart gadgets
  2. Keep Firmware Up-to-date – Ensure you are still receiving updated firmware patches from manufacturers regularly
  3. Separate Networks – Create a separate network for IoT devices to isolate them from other network users and sensitive information.
  4. Use encryption – Ensure your data-in-transit is encrypted by using HTTPS or SSL on routers, and HTTPS enabled apps when accessing gadgets remotely
  5. Be selective with the number of smart home devices – focus on essential ones only.


IoT has brought convenience to our daily lives, but it’s important to take precautions against security risks that come along with having connected devices in our homes. By following these tips, you can help secure your smart home devices and protect yourself from potential hacking threats.

In conclusion, understanding how IoT can impact network security is crucial in maintaining a safe and secure smart home environment. By taking proactive measures such as regularly updating firmware, changing default passwords when setting up new IoT devices, creating separate networks for these types of gadgets, using encryption methods like HTTPS/SSL protocols on routers or accessing them remotely via apps with built-in encryption features can help mitigate security risks associated with connecting everyday living appliances online.


Sure, here are three popular FAQs related to how IoT is impacting network security:

Why do IoT devices pose a threat to network security?
IoT devices often have weak or default passwords and are designed with convenience in mind rather than security. This creates vulnerabilities that cybercriminals can exploit to gain access to the larger network, including sensitive data stored on connected systems.

How is the use of IoT devices changing traditional network security practices?
Traditional firewalls and antivirus software alone may not be enough to protect against threats posed by insecure or compromised IoT devices. Network segmentation, device authentication protocols, and additional layers of encryption are becoming increasingly important for securing networks that incorporate IoT technology.

What steps can be taken to improve the security of a network that uses IoT devices?
To improve the security of a network with IoT devices, it’s essential first to identify all connected devices and their level of risk potential by assessing their usage patterns and sensitivity levels.
Then implementing strong password policies such as two-factor authentication across all smart products within your home.
Next monitoring traffic logs looking for any irregular traffic coming from home router could indicate unauthorized infiltration attempts into your home Wi-Fi system
Creating virtual local area networks (VLANs) to separate less trusted components from critical functions.
Finally regular maintenance like updating firmware version/checking compatibility/monitoring uptime will help you avoid leaving unsecured gaps in your endpoints’ armour
By taking these steps continuously over time will increase user engagement while protecting them against threats posed by insecure or misconfigured smart technologies.
