Abstract
IPv6 is the next generation for Internet Protocol, also known as IPng. IPv6 was
developed by the Internet Engineering Task Force (lETF) to replace the Internet
Protocol version 4 (IPv4). Tunneling techniques are common mechanisms in the
early deployment of IPv6 to connect between two isolated IPv6 LANs or hosts by
using the IPv4 infrastructure. This thesis focuses on Teredo tunneling which is an
automatic tunneling mechanism that enables hosts located behind one or more IPv4
NATs to obtain IPv6 connectivity by tunneling packets over UDP.
This research particularly works on the analysis of Teredo bypasses network security
problems where among them, source routing after Teredo client is the focus of this
research. The attackers can exploit the IPv6 functionality Routing header to launch
their attacks through the Teredo tunnel. In this research we proposed Teredo Client
Protection Algorithm (TCPA) to protect the Teredo client from the attackers detour.
Since the attackers can exploit the source routing feature to bypass network security.
The proposed method for solving this problem prevents the attacker from bypassing
the network security through the routing headers hole.
