IPv6 security: improvements and implementation aspects

Abstract

IPv6 provides many new possibilities and features and also enables significant improvements in confidentiality of information transmitted through the network. Many modifications implemented in IPv6 are expected to directly or indirectly improve security environment for devices connected to both public and private networks. Security features developed for IPv6 are known as IP Security (IPsec). This protocol assures a certain level of security, but does not solve all existing security issues. In this paper methods for network security improvement by implementation of firewalls and intrusion detection systems were analyzed. Furthermore, the methods for ensuring privacy in IPv6 were evaluated and available tools were analyzed. Security tests were done and comments of their results were given. Finally, suggestions about network security improvement and implementation of security mechanisms in IPv6 networks were given.
