无线通信网络通过手机或PDA可以将Internet服务随时随地带到用户的身边,但同时也将带来威胁。除了物理层传输方式与有线网络的区别外,无线网支持的通信业务和有线网基本一致,因此,目前有线网络面临的安全问题正直接影响着无线网络的安全。同时,由于无线网在物理层以广播方式发送报文,所以,无线网正面临着比目前网络安全更严重的问题:如假冒攻击,非法接入坊问,非法使用资源;极易受窃听攻击,使信息机密泄露;信息容易被截获和修改;容易受到病毒攻击和黑客入侵等等。 本文将对WLAN和Bluetooth的安全问题和一些漏洞进行分析。
Wireless communication networks can bring Internet services to the users anytime, anywhere through mobile phones or PDAs, but they also pose threats. In addition to the difference between the physical layer transmission and the wired network, the communication services supported by the wireless network are basically the same as the wired network. Therefore, the security problems currently faced by the wired network are directly affecting the security of the wireless network. At the same time, because wireless networks broadcast packets at the physical layer, wireless networks are facing more serious problems than current network security: such as counterfeit attacks, unauthorized access, and illegal use of resources; extremely vulnerable to eavesdropping attacks , So that confidential information leaks; information is easily intercepted and modified; vulnerable to virus attacks and hacking and so on. This article will analyze WLAN and Bluetooth security issues and some vulnerabilities.
