Securing your home network in 2025 involves updating default router settings such as password and network name.Using strong passwords with WPA3 encryption is recommended to prevent hacking and eavesdropping.Keeping your router's firmware updated is crucial to prevent known security vulnerabilities.Setting up a separate guest network can isolate guests from your main network for added security.Ensuring all smart home devices have secure passwords, updated firmware, and connecting them to the guest network can enhance security.Using a strong firewall, enabling device-level security, and employing DNS filters or parental controls are essential security measures.Disabling unused features like UPnP, WPS, and remote management can reduce the risk of attacks.Employing network monitoring tools and VPNs on public networks are recommended for monitoring and encrypting traffic.Backing up critical data periodically is advised to protect against data loss from ransomware or hardware failure.Overall, developing good security habits like regular checks, software updates, and strong passwords is key to a secure home network.
