IPv6 Security Threats and Possible Solutions

In comparison to IPv4, IPv6 provides many improvements considering simplicity, routing speed, quality of service and security. IPv6 brings significant improvements in mechanisms for assuring a higher level of security and confidentiality of the transmitted information. Nevertheless, it is still necessary to take care of network security. This paper analyzes how actual security threats and different types of attacks affect IPv6 networks. IPv6 specific security issues and issues due to different transition mechanisms are also analyzed. Certain security tests have been done and their comments have been given. Finally, some possible solutions for a number of security threats in IPv6 networks have been given.
