Technology, Issues, and Solutions by David Clark Wireless Security Technology, Issues, and Solutions by David Clark

Introduction Advantages of Wireless Technologies Trade-offs Convenient Easy to use Trade-offs Susceptible to security violations Requires more user knowledge

The Technologies Wireless Local Area Networks 802.11 Wireless Personal Area Networks Bluetooth Wireless Handheld Devices PDAs Phones

Wireless Local Area Networks IEEE defined the 802.11 standards for wireless networking 802.11 intended to provide the functionality of Ethernet, wirelessly using radio waves

Issues Default Hardware Settings WEP Encryption Weaknesses Mad-in-the-middle

Solutions WEP WPA/WPA2 MAC Filtering Disabled SSID Broadcasting End-to-end Encryption

Wireless Personal Area Networks Bluetooth was designed to be the basis of the Personal Area Network (PAN) a way for devices within relatively close proximity to communicate wirelessly with one another

Issues Default Settings Passkeys Faulty Encryption Scheme - E0 Privacy “Bluejacking” “Bluesnarfing”

Solutions Knowledgeable Use PIN Settings Limit Range Non Promiscuous

Wireless Handheld Devices PDAs Mobile Phones Most PDAs and mobile phones now contain sensitive personal and business information

Issues Sync “hijacking” Bluetooth/802.11 Data Access Malware Eavesdropping Loss/Theft

Solutions Secure Settings Password Protection Encryption Settings

Conclusion Risks are inherent in any wireless technology Some of these risks are similar to those of wired networks; some are exacerbated by wireless connectivity; some are new Knowledgeable users and sound security measures can make wireless technology practical and safe.
