It’s important to ensure that you have an internet service provider with good security ratings. If your ISP has a low-security rating, you should switch to one with a high rating, like Optimum (formerly Cablevision). To make sure that your home network is safe from hackers, use WPA2 encryption on your router and make sure that they use passwords or pins for their networks. You should also avoid using public Wi-Fi networks when possible, and never connect to unfamiliar Wi-Fi networks without first verifying that they are legitimate by using a credential checker.
