When shopping for a router, check for features like intrusion detection systems and the ability to create multiple SSIDs. Brands known for security include ASUS, Netgear, and TP-Link, which often provide user-friendly interfaces for managing settings.
Setting up a guest network
Creating a guest network is an effective way to isolate your smart home devices from visitors. This network allows guests to access the internet without connecting to your main network, reducing the risk of unauthorized access to your personal devices.
Most modern routers offer an option to set up a guest network easily. Ensure that the guest network has a strong password and consider limiting its access to specific devices or services to enhance security further.
Disabling WPS
Wi-Fi Protected Setup (WPS) can simplify connecting devices but poses security risks. Disabling WPS prevents potential attackers from exploiting its vulnerabilities to gain access to your network. This step is especially important for smart home environments where multiple devices connect to the internet.
To disable WPS, access your router’s settings through its web interface. Look for the WPS option in the wireless settings and turn it off. This action adds an extra layer of security to your network.
Managing device permissions
Managing device permissions is essential for maintaining a secure smart home network. Regularly review which devices are connected and ensure they have the minimum necessary permissions to function. This practice limits potential entry points for cyber threats.
Utilize your router’s interface to monitor connected devices and their access levels. Consider setting up parental controls or access restrictions for less secure devices, ensuring that only trusted devices can communicate with each other on your network.
