Yes, viruses *are* theoretically possible on these platforms, but let's be honest here - even if you included all of the platforms, you'd only intercept another 1% or so viruses, tops.Well, if you let systems on the network without the secret handshake, what's to stop people from connecting Windows boxes with the "security" software disabled so it doesn't answer the "I'm Infected" question? Or the next virus can take over the Cisco secret handshake port and always answer "I'm Ok" when ever the network asks it a question. How does the Self-Protecting Network tell the difference between a non-infected Mac or Unix machine from a Typhod Mary Windows bo if you are depending on software on the system to answer the question? Yes, some level of security works when every obeys the rules. But the current problem ISPs have is not everyone obeys the rules.
Or maybe the problem is yet another single-vendor impostion of a "global" protocol standard.
