| 摘 要： | 在交换技术的网络中VLAN为网络的管理与有效抑制广播风暴提供了技术支持,同时在Trunk端口配置、802.1Q协议封装以及VTP配置等实施中也为黑客的攻击留下隐患。常见的攻击形式有MAC洪泛攻击、802.1Q和ISL标记攻击、双封装802.1Q/嵌套式VLAN攻击、VLAN跳跃攻击、VTP攻击等。针对以上攻击文中提出了端口安全配置、Trunk端口配置以及VTP协议的安全配置等措施,有效地防范黑客对网络的攻击。

| Abstract: | In the network of exchange technology,VLAN provides technical support for network management and restricting network broadcast storm effectively,at the same time it brings hidden danger for hackers attack at the Trunk port configuration,802.1Q protocol encapsulation as well as the VTP configuration.These common attacks include MAC flooding attack,802.1Q and ISL tag attacks,two-package 802.1Q/nested VLAN attacks,VLAN hopping attack as well as VTP attack.Aiming at above attacks,this paper puts forward some me... |
