IPv6 Security

The newer IPv6 protocol has solved some, but not all, of the security problems found in IPv4 networks. One example is the mandatory inclusion of IP Security (IPsec) in the IPv6 protocol, which makes it fundamentally more secure than the older IPv4 standard. However, given its flexibility, the IPv6 protocol introduces new problems. A mobile IP protocol is built into the IPv6 protocol, and security solutions for this protocol are still under development.

In addition, the dynamic configuration flexibility of IPv6 (such as Stateless Address Auto-Configuration) could also become a serious security problem, if not implemented correctly. The overall enhancements in IPv6 may provide better security in certain areas, but attackers might still be able to exploit part of the protocol. This paper will focus on the security improvements over IPv4 while also looking at the possible threats to IPv6.
