3. Avoid Open Wireless Networks
Security experts recommend avoiding open wireless networks, even in the United States, without using a VPN to tie into the corporate network. Freely available tools make it easy for an attacker to use a victim's credentials and view unencrypted browsing sessions. In 2010, a Firefox browser plug-in called Firesheep enabled users to snoop on individuals on open Wi-Fi networks. At conferences abroad, users should ensure that their devices are being connected to the proper access point, security experts say. Global VPN service providers also exist to help secure communications on open Wi-Fi networks. In addition, some mobile device management vendors extend corporate VPN capabilities to employees. Mobile Active Defense, an MDM vendor, enables IT teams to set corporate policy based on employee location.
