I switched from Xfinity to Astound recently and have some questions on security and how to ensure I am protected or if I even need to worry much at all. With Xfinity I had a simple setup, Modem connects to Xfinity via coax and then my network from there. With Astound I now have a ethernet connection in the apartment I can do what I want with. After some investigation connecting directly to it I can see around 100 different devices with their respective MAC addresses and names using advanced IP scanner. After seeing this I reconfigured everything to run through a router instead of a switch and now am only able to see their respective public IP addresses. The modem is managed by the ISP and not the landlord/building if it maters. I haven't done any more configuration from there but should I be concerned about security with this setup? Its something I'm unfamiliar with and want to make sure I am not at much risk (at least compared to the original setup where I owned the modem).
