Analyzing Computer Security: A Threat / Vulnerability / Countermeasure Approach

10. Do You Hear What I Hear?

Chapter Spotlight

• Wireless or WiFi network communications

• Vulnerabilities caused by the exposed nature of wireless networking

• Wired Equivalent Privacy (WEP) as an initial wireless security approach that unfortunately had many faults

• WiFi Protected Access (WPA), the successor to WEP
