A firewall is a form of network security designed to protect a computer network from unwanted access. It watches for network traffic based on a set of rules and performs certain actions, such as blocking the connection, allowing the connection, or logging and monitoring the connection attempts for audit purpose. This helps protect your home network from malicious attempts to gain access to your personal data or to take control of connected devices.
To ensure the security of your home network, you should take the following steps:
- Regularly update the router firmware
- Disable remote administration
- Change the default username and password for the router
- Enable encryption and authentication protocols
- Use a VPN connection
- Set up a firewall
