Wi-Fi is a wireless networking technology that uses the 802.11 standard developed by IEEE to allow for wireless local area network computer communication in public spectrum bands. Securing wireless networks is important and can be done by securing all wireless devices and educating users, actively monitoring the network for weaknesses, and using stronger security protocols like WPA2 instead of the deprecated WEP. While SSL encryption provides some security, public Wi-Fi connections can still be intercepted using man-in-the-middle attacks, so using a VPN service or SSH tunneling can further improve security when connecting over unknown networks.

2. WI-FI Wi-Fi is a wireless networking technology used across the globe. Wi-Fi refers to any system that uses the 802.11 standard, which was developed by the Institute of Electrical and Electronics Engineers (IEEE) and released in 1997. The term Wi-Fi, which is alternatively spelled WiFi, Wi-fi, Wifi, or wifi, was pushed by the Wi-Fi Alliance , a trade group that pioneered commercialization of the technology.

3. 802.11 802.11 is a set of standards for wireless local area network (WLAN) computer communication, developed by the IEEE LAN/MAN Standards Committee (IEEE 802) in the 5 GHz and 2.4 GHz public spectrum bands.

6. Securing a wireless network Possible steps towards securing a wireless network include: All wireless LAN devices need to be secured All users of the wireless network need to be educated in wireless network security All wireless networks need to be actively monitored for weaknesses and breaches

7. You are using WEP? You are damn stupid. You are damn stupid. WEP is a deprecated algorithm to secure IEEE 802.11 wireless networks. It is possible to crack and get code very fast depending on traffic Hackers use Aircrack-ng and they are having fun!

8. Use WPA or WPA2 instead Protocol was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). Hackers can crack password only using Brute Force Attack. So don’t use WPA passwords like “password”, “administrator” and any other password you can find in dictionary.

10. You think that SSL is safe? Kind of... :) It's completely possible to sniff out https (ssl encrypted) Using MITM (man in the middle) attacks Route all of your https traffic to MITM (e.g. using ARP spoofing) Intercept all traffic from the web server Send you a fake self signed certificate And once you accept it thinking the site is secure, everything you do goes through MITM first http://www.youtube.com/watch?v=Aak6-B3JORE Using Backtrack and Ettercap

11. How I secure my traffic? SSH tunneling SSH tunneling I have installed Ubuntu server with SSH and squid proxy at home with fixed IP I use small app on OS X SSH Tunnel Manager and tunnel proxy port to localhost:6023 In firefox I use proxy localhost:6023 On Windows XP I use Tutty to do the same thing

12. Pay for security Pay for VPN service www.witopia.net - $39.99/year www.publicvpn.com - $6.95/month OR $69.95/year Pay for tunneling service www.secure-tunnel.com - $9.95/month OR $99.95/year
