IPv6 Not Without Network Vulnerabilities
IPv6 offers native IPSec for encryption.
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.
