We have semi centralized various things in the past such as IP assignments and our beloved DNS root servers. Would it not also make sense to handle common security checks in a similar manner? In creating an authority to handle this, we cut back on the amount of noise issued. I bring this up because the noise is getting louder. More and more networks are issuing their own relay and proxy checks. At this rate, in a few years, we'll see more damage done to server resources by scanners than we do from spam and those who would exploit such vulnerabilities. I know that this is more service level than network level, except for the arguments continue to escalate over the rights of people to scan a network. These arguments would be diminished if an authoritative body handled it in a proper manner. At what point do we as a community decide that something needs to be done? Would it not be better to have a single test suite run against a server once every six months than the constant bombardment we see now? -Jack
