Hospitality Industry Internet Security Risks: Hotels Can Offer Wireless Internet With WPA2 (Wi-Fi Protected Access 2) To Offer Guests Greatest Wireless Security

IS WIRELESS INTERNET IN HOTELS SAFE?

• The short answer is: No. Wi-Fi was born to be convenient, not secure. Unsecured, unprotected wireless is everywhere. When a device connects to unprotected Wi-Fi, all the data stored on that device is available to a hacker with the proper sniffing tools.
• The longer answer is: It depends on what kind of wireless that is provided.
• Free, unsecured Wi-Fi is the least secure. Any Wi-Fi connection, whether in public, at home, or in the office, that is shared with anyone with any wireless device, lacks encryption of the data packets streaming from the connected devices.
• A simple Firefox add-on called Firesheep can allow anyone with a Firefox browser to sniff out other devices using the same Internet connection, and to spy on their browser activity. Even if the victim’s login is encrypted, once they visit an unencrypted site, their data becomes vulnerable.
• Wi-Fi with a WEP encryption is slightly more secure. Wired Equivalent Privacy was introduced in 1997 and is the original version of wireless network security. But WEP has been cracked, hacked, and decimated.
• Wi-Fi with a WPA encryption is better. Wi-Fi Protected Access is a certification program that was created in response to several serious weaknesses researchers found in WEP, the previous system. WPA and WPA2 are tougher to crack, but not impossible.
• Mobile Broadband has a degree of encryption that has been cracked, but the necessary hardware isn’t widely deployed by criminals. Researchers have demonstrated how the system can be hacked, but it’s still more secure than other options.
• WPA2 Wireless Internet IS THE MOST SECURE
