How do I stop bad router permissions that allow attackers to modify configuration or disrupt traffic?

To stop bad router permissions that may allow attackers to modify configurations or disrupt traffic, first, ensure that the router's firmware is up to date to patch any security vulnerabilities. Change the default administrative username and passWord to strong, unique credentials to prevent unauthorized access. Additionally, disable remote management features unless absolutely necessary, and enable firewall settings to restrict incoming connections. Regularly review and limit user permissions and monitor network traffic for any unusual activity.
