Take precautions when using public Wi-Fi as cyber crime rates increase

Although itís great having access to email, social networking and online shopping anywhere, anytime, such convenience comes with a certain amount of risk, according to Jennifer Fischer, Head of Americas Payment System Security, Visa Inc.
"Unless youíre hyper-vigilant about using secure networks and hack-proof passwords, someone sitting at the next table – or halfway around the world – could be watching your every move online and stealing valuable personal and financial information right off your device," says Fischer.
"There are two primary potential dangers with Wi-Fi," notes Fischer. "The first is using an unsecured network – as many public hotspots are. With a little know-how and the right tools, cyber criminals could easily eavesdrop on your online activity.
"The second hazard is phony wireless networks that impersonate legitimate Wi-Fi hot spots. You think youíre logged onto a trusted network, but instead a cyber criminal has hijacked your session and can see all the private information you access or input."
When using public Wi-Fi networks, always follow these safety precautions:
• Change default settings on your laptop, smart phone or tablet to require that you must manually select a particular Wi-Fi network, rather than automatically accepting the strongest available signal.
• Avoid any network connections your device lists as "unsecured" (look for the "lock" icon). But if you must log on to a public network, avoid websites that require log-ins and passwords – e.g., bank accounts oremail.
• Ask for the exact name of the establishmentís hot spot address – donít be fooled by look-alikes.
• Only send personal data via Wi-Fi to encrypted websites (those whose addresses begin with "https" and display a lock icon). To be safe, you may want to avoid conducting financial transactions on public Wi-Fi altogether; instead, use your secure home network.
• Consider using a third-party virtual private network (VPN) product to encrypt your Internet traffic.
• Regularly update virus and spyware protection software, make sure firewalls are on, and load operating system updates as soon as they become available, whether for your computer or smart phone.
• Turn off Wi-Fi on your device when itís not in use.
• Never leave a computer unattended while signed in and always sign out completely at the end of a session.
• Keep an eye out for "shoulder surfers" who watch as you type .
Finally, change passwords regularly and use different ones for each website you visit. Use a mixture of letters, numbers and symbols and avoid common words and phrases. Security experts recommend using at least 12 characters instead of the minimum eight characters commonly required.
Cyber crime is a booming business. According to the 2012 Norton Cybercrime Report, its global price tag topped $388 billion last year, more than the global black market in marijuana, cocaine and heroin combined. It impacts individuals, small and large businesses and governments alike.
Being able to access the Internet anywhere anytime can be a great convenience and time-saver. Just make sure you know what precautions to take when using public Wi-Fi networks.
