How can you secure your network in the age of IoT and 5G?

1 Update your firmware and software

One of the most basic and essential steps to secure your network is to keep your firmware and software updated. Firmware is the program that runs on your network devices, such as routers, switches, firewalls, and access points. Software is the application that runs on your computers, smartphones, tablets, and IoT devices. Both firmware and software can have vulnerabilities that hackers can exploit to gain access to your network or data. Updating your firmware and software regularly can fix these vulnerabilities and improve your network performance and security.

2 Use strong encryption and authentication

Another important step to secure your network is to use strong encryption and authentication methods. Encryption is the process of converting your data into a code that only authorized parties can read. Authentication is the process of verifying the identity of the users or devices that access your network. Encryption and authentication can prevent hackers from intercepting, modifying, or stealing your data. You should use the highest level of encryption and authentication available for your network devices and applications. For example, you should use WPA3 for your Wi-Fi network, TLS for your web traffic, and VPN for your remote access.

3 Segment your network

Segmenting your network means dividing it into smaller subnetworks that have different access levels and security policies. Segmenting your network can help you isolate and protect your sensitive data and devices from unauthorized or malicious access. For example, you can segment your network into a guest network, a corporate network, and an IoT network. You can then apply different firewall rules, VPN settings, and encryption standards to each segment. This way, you can reduce the attack surface and limit the damage in case of a breach.

5 Educate your users

Educating your users means providing them with the knowledge and skills to use your network and devices securely and responsibly. Educating your users can help you prevent human errors, negligence, or ignorance that may compromise your network security. For example, you can educate your users to create strong and unique passwords, avoid phishing emails, use secure Wi-Fi networks, and report any suspicious or unusual activity. You can also educate your users to follow your network security policies and guidelines, such as using VPN, updating their software, and backing up their data.
