I just got the internet connection from AT&T and it is basically a DSL Modem with WiFi router built in. I am thinking about attaching a NAS to the router via USB port in the back of AT&T device.
My question is how can i secure my internal home network. Any software recommendation?
I want to actually protect the entire home network, not just one computer? Do I need any kinda firewall (hardware) or something? please advice.
