Are there any practical ways to monitor my home network traffic and detect if any devices on my network are compromised?


Not sure about monitoring, but I always put any device I don’t trust on a jailed LAN/AP.


A lot of home routers will give you a traffic graph - if yours doesn't you can either find one that does or flash/build one.

I currently run opnsense which has an ok graph out of the box, I haven't fiddled with it to see if there's something fancy I could do here.

I also used to use IPFire which was slightly clunkier but had a nicer usage graph.


Your ISP should give you a bandwidth usage meter.


Haha. My ISP barely gives me an Internet connection


You can rest assured your ISP can produce the graph. If your graph reaches a certain shape, they'll start shaping your traffic for you to something they prefer all while charging you the normal rate.


Aren't cisco machines compromised by default by design? I imagine all of them are at this point. I wouldn't worry too much about it.
