2. Abstract • Discusses the current security measures available for the IPv4 infrastructure. • Common security mechanisms including some kinds of attack and IPsec.

3. Introduction • The current version of IPv4 does not use IPsec by compulsion, so there are some kinds of attack on IPv4. • IPv6 succeeds, it possesses some new features: 128 bit address field, highly effective IP header, Qos, encryption and authentication, and mobility.

4. The three types of network attacks • Eavesdropping • Tamper & Forge Attack • Denial of Service Attack

5. The three types of network attacks - Eavesdropping • In Ipv4, network communication is sometimes transmitting without encryption.

6. The three types of network attacks - Eavesdropping

7. The three types of network attacks - Tamper & Forge Attack • Attacker may use special program to manufacture IP packet, make the packet seemingly from valid address inside the web. • After acquiring access authorization by valid IP address, attacker can modify, reroute, and delete data.

8. The three types of network attacks - Tamper & Forge Attack

9. The three types of network attacks - Denial of Service Attack • Attacker may use one or some of the following methods: flooding packets until a computer or the whole network cease operating; preventing legitimate network traffic, which will cause lost of network resource.

10. The three types of network attacks - Denial of Service Attack

11. Security Measures of IPsec Against Above Attacks • IPsec provides three different forms to protect private data transited through public and private network: Authentication, Integrity test, Confidential.

12. Threat In IPv6 Network • Password Attack • Secret Key Attack • Application Layer Attack

13. Threat In IPv6 Network -Password Attack

14. Threat In IPv6 Network -Secret Key Attack

15. Threat In IPv6 Network -Application Layer Attack

16. Principle Of Attacks In IPv6 • Acquire host password in WAN, intrude the hos. • Distributed Denial of Service (DDos) attacks.

17. Conclusions • IPv6 is the new version of the Internet protocol. • IPsec in IPv6 improve the security in network. • IPv6 will also bring some new problems of security. We must use some others measures to ensure the security in IPv6.
