Seven Security Policies for the IPv6 Network of the Future

“The switch from IPv4 to IPv6 will force many organizations to
rethink the way their networks are defended. The result will be a
shift away from the “guilty until proven innocent” attitude to
incoming network traffic, toward one of “paranoid openness.”

“That’s the view of Eric Vyncke, a Distinguished Engineer at
Cisco Systems. Talking at the RSA Conference in London last month,
he said that it is only when organizations become more open to
incoming traffic that they will get the full benefits of IPv6 .

“Many companies have delayed thinking about a move to the next
generation IPv6 Internet protocol because there is little benefit
in being a “first mover,” but sometime in the next few years the
remaining free IPv4 IP addresses will be used up. When that happens
the world will be forced over time to move to IPv6, which offers
128 bit addresses (instead of IPv4’s 32 bit addresses), resulting
in a staggering 2 ^ 128 different possible IP addresses.”
