Wireless networking offers convenience but comes with significant security risks. This presentation by Colby Carlisle outlines how local-area networks communicate via high-frequency radio waves, eliminating the need for physical access. However, issues like confidentiality and integrity concerns arise, along with vulnerabilities in commonly used security technologies. Key strategies to secure your network include using strong encryption methods such as WPA2, changing default settings, disabling SSID broadcasts, and enabling MAC address filtering. Stay informed and protect your wireless connections against potential attacks.

Wireless Security Presented by Colby Carlisle
Wireless Networking Defined • A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.
Issues • No need for physical access • Easy and convenient to use • Confidentiality and Integrity concerns for users • Technologies commonly used to secure networks are vulnerable to attacks
The Tradeoff • Linksys Routers • Zero Configuration
Be careful whom you associate with... • Malicious Associations • Exploits how users connect to AP’s • Can create backdoors into other networks • Man-in-the-Middle • Hotspotter
What can you do? • Use encryption • WEP • WPA • WPA2
WEP • Wired Equivalent Privacy • Still widely used • Encryption algorithm flawed • Vulnerability widely known • Kismet
WPA • WiFi Protected Access • Intermediary step between WEP and WPA2 • Temporal Key Integrity Protocol • Personal vs. Enterprise
WPA2 • Implements mandatory elements of the 802.11i standard • Advanced Encryption Standard
Steps to securing your network • Use the best encryption possible • Change your router’s default configuration • Disable the SSID broadcast option • Disable DHCP • Enable MAC address filtering if possible
