I’m having trouble conceptualizing the attack strategies here. I also lack much understanding of what (exactly, precisely, at the technical level) federation is so I don’t understand how defederation is a defense against those attacks.
Would someone help me break this down conceptually? Are there any analogies? Is this like closing the gate of a castle? Is it like quarantining infected people? Like blocking a phone number? Not loaning someone money?
Please don’t just say “yes to all those analogies”. I’m casting about for understanding here.
How can I better understand OP’s argument here? (I have a background in tech and understand passwords, certificates, signatures, etc if that helps). Is email a federated thing? What’s federation precisely?
