Re: BGP security in practice
Yes, but... A protocol in which principal A's misconfiguration can seriously harm principle B is more broken than one in which it cannot. That's why the protocol for crossing a busy street includes "In addition to the light status, look for actual moving vehicles." That way, you don't get run over by someone else's misconfiguration. Time for a new metaphor, methinks. - Eric Anderson Thus spake email@example.com (firstname.lastname@example.org): > > Every protocol is vulnerable if the principals are mis-configured (i.e. do not > follow the protocol). > > The protocol for crossing a busy street at the light involves checking for > the green light before crossing the street.
