This is an intriguing step by Senator Warner, and it poses several follow up questions. I am personally unsure how an ISP can govern the devices on the inside of any user’s home router or firewall. Obviously, from a technical perspective, certain outbound traffic from a home can be filtered, but it would be very difficult to determine the configuration or firmware version of the source device.
ISP’s, however, are capable of assisting in the fight against DOS and DDOS attacks, depending on the architecture of their infrastructure and the investments they are willing to make to build dynamic solutions for routing and “blackholing” malicious traffic.
I am glad to see this debate coming to the forefront and receiving some well-deserved attention. The answers, however, are not quite as clear as we would like them to be.
