Title: | Security assessment of IPv6 infrastructure in Hoan My medical corporation | Authors: | Nguyen Quynh | Keywords: | Security assessment;IPv6;Medical corporation | Issue Date: | 2017 | Publisher: | Vietnamese-German University | Abstract: | This thesis assess the security of IPv6 in network of Hoan My Company, which mainly base on IPv4. Network infrastructure comprise network devices, computers machine, servers and other peripheral devices connected with each other. All of them communicate with each other by IPv4 protocol. However, with the development of Next Generation Internet and internet capable devices, venders now enable IPv6 default and work compatible with IPv4. Company network security does not aware about the risks and vulnerabilities from IPv6. Base on the research and assessment network infrastructure of company, it is clearly that enabling the IPv6 by default would make the network vulnerable. Router advertisement flooding attack could make performance of computer increase exponentially and slow down. TCP half-open flood sync, which is an old style of attack since IPv4, also cause performance problem on the target computer. Assessment also test the case when IPv6 enable for purpose, the test show that other attack style could be exploit same as IPv4 such as man in the middle attack, duplication address attack, spoof DHCPv6 or even perform the Cisco access control list evasion by exploit the complexity of extension header chain in IPv6. From that, the network of company have to deploy the mitigation to reduce the threat of IPv6 vulnerabilities. Company could takes the advantages from active directory and deploy Network Access Control with dot1x for limit the attacker from outside. On the other hand, using the IPv6 Access Control List is also good solution to mitigate the attacks. IPv6 transition should be considered as plan to migrate IPv4 network to IPv6. There are many techniques that support transition from IPv4 to IPv6 such as tunneling and NAT64. The security of after implement IPv6 must also consider properly because protocol like tunneling technique could be exploit such as routing loop with ISATAP router. Before migration company network to IPv6, company should plan and test in advance. Migration will take time and risk, therefore it should implement in order to avoid network outage and services interruption. |
