internet policy advisors RFC3552/BCP72 describes an Internet Threat model that has been used in Internet protocol design. More than eighteen years have passed since RFC3552 was written and the structure and topology of the Internet have changed. With those changes comes a question: has the Internet Threat Model changed? Or, is the model described in RFC3552 still mostly accurate? This draft attempts to describe a non- exhaustive list of changes in the current threat environment. It finds that there are both qualitative and quantitative differences from the environment described in RFC3552 and is intended as input to the IAB program on the Internet threat model started in 2020.
