Review of Preventive Security Mechanisms for Neighbour Discovery Protocol
The exponential and phenomenal growth of internet-connected devices in recent years has exhausted the pool of Internet Protocol (IP) addresses for new allocation in many regions. A new protocol, IP version 6 (IPv6) was developed in 1998 in anticipation of such situation as well as to improve network communications in general. IPv6 offers improvements in several areas over IPv4 such as security by including a built-in security mechanism, IPsec. In addition, it also introduced new functionalities such as neighbor discovery which were specified in Neighbor Discovery protocol (NDP). NDP is a core protocol in IPv6 network for link local communication. Unfortunately, IPsec is not usable with NDP due to bootstrapping problem resulting in IPv6 local communication to be left unsecured and IPv6 nodes vulnerable to insider attacks. There are many mechanisms proposed to protect IPv6 network from NDP-related attacks. This paper reviewed existing preventive mechanisms against NDP-based attacks in IPv6 network.
