IoT devices growth is helpful but it also brings cybersecurity dangers. Many IoT devices lack many security features, making them susceptible to attacks that can lead to network compromise. Studies have found that over 80% of IoT devices are not properly secured, which can result in data breaches and illegal access.
For network security, IoT devices need to be secured. Network division, strong authentication, and software updates can all help to lessen the vulnerabilities. Organizations should train employees, encrypt IoT devices, and keep an eye on their activity to prevent dangers.

Secure IoT Devices
Step 1. Update The Devices.
This means that there must be an installation of the latest software and security updates on any IoT devices. It becomes very simple for attackers to attack those devices which have old updates.
Step 2. Authentication And Passwords.
It is a step in making sure that each device has a strong, unique password for its security and uniqueness. The password should at least have 12 characters with a combination of numbers, uppercase, and lowercase letters, and special symbols. Always use Two-Factor Authentication or Multi-Factor Authentication if available such as biometrics, one-time password, email code, and sms authentication.
Step 3. Separate The Network And Firewalls.
Isolate IoT devices on a different network to limit access to critical systems. An example of this is creating VLAN (Virtual LAN) which prevents the devices from connecting to sensitive systems. Enable the firewall, which will block unwanted access.
Step 4. Scan For Vulnerabilities.
Scan devices for known vulnerabilities. Security monitoring technologies will help in identifying suspicious activities. Examples of these technologies are Intrusion Detection and Prevention Systems (IDPS), Network Traffic Analysis Tools, IoT Security Platforms, and Behavioral Analytics Tools. You can view the top 10 IoT Security Tools on this site.
Step 5. Disable Unused Features And Services.
Disable unused features or services to reduce potential entry points for attacks. Reduce open ports and unnecessary protocols as inactive features or services might still be exploited by attackers. Default services and protocols on your devices may be active even though they are not in use, which leads to creating potential vulnerabilities. Examples of features you can disable are Telnet and SMBv1.
