Tech World takes a look at vulnerabilities in the network with IPv6 and what some companies are doing to protect themselves and their customers in this new internet. Security concerns are “not a non-issue”, but in recent years developers have become better at abstracting the network layer. IPv6, for example, offers native IPSec for encryption and each packet has authentication built in, properties which give it a reputation for a higher level of security than IPv4.
“’One issue that comes up is operating systems that have IPv6 turned on by default,’ he said. ‘Anyone who has Windows 7, a Mac, or some versions of Linux is running IPv6 without knowing. And tunnels may circumvent the control people have in place.’”
