交换机安全功能在防黑客攻击中的应用研究

Application Research of Switch Security Functions in the Prevention of the Hacker Attack

构建安全的计算机网络,是人们追求的目标。然而计算机病毒的网络传播和黑客的攻击却不断地对网络安全带来新的挑战。人们在考虑安全防护时,往往重视网络层和应用层的安全防护,而忽略了数据链路层的防护。通过交换机安全功能和黑客的攻击方法两个角度分析研究,探讨了数据链路层设备——二层交换机的安全功能在防御或者缓解黑客攻击方面的有效对策。

To construct the secure computer network is the goal of people.However,the computer virus and hacker attacks are constantly bring new challenges to network security.People in the consideration of security and protection,usually pay attention to security of network layer and application layer,while ignoring the protection of data link layer.From two angles of attack methods and switch security function,the effective defense countermeasures of the security function of layer 2 switch is analyz esed as the device.of data link layer.
