IPv6 and IPv4 Threat Review with Dual-Stack ConsiderationsLancaster, Troy (2006) IPv6 and IPv4 Threat Review with Dual-Stack Considerations. Full text available as:
AbstractThe gradual transition from IPv4 to IPv6 requires network administrators to become aware of the next generation protocol and the associated security risks. IPv6 provides many new features, which directly or indirectly improve the security environment for devices connected to both public and private networks. However, the very presence of IPv6 makes networks susceptible to attack. By transitioning to IPv6 without adequate precautions, an adversary can easily bypass a networks security infrastructure. Most administrators are aware of the security considerations with IPv4, however, are lacking such knowledge for IPv6. This paper provides a condensed review of the most common attacks in IPv4 and compares them to IPv6 and its transition mechanisms. Specific emphasis is placed with dual- stack deployment where a modified security model is proposed. Finally, guidelines and recommendations are given to outline the key considerations throughout the deployment process.
