I hear family and friends talk about how much SPAM they get — up to hundreds of messages each day. They say it takes forever to sort through their inbox. I tell them I don’t have a problem; I use a verification service. Many times, they ignore my advice, probably thinking they’ve tried that — […]

Like every other technology, Wi-Fi is constantly evolving. You buy the latest-and-greatest networking gear, and in a few years it’s considered old and slow. The alphabet soup of wireless standards has expanded from a, b, g to now include n—plus y for enterprises. The signals are faster, stronger and more secure. While upgrading the brains […]

As you’re sipping your favorite drink or getting a bite to eat while surfing the net from a Wi-Fi hotspot, others could be sipping or gulping down your personal information.

As much as we use e-mail to conduct business today, most small businesses routinely send sensitive messages ‑‑ often containing social security numbers, business deal discussions, corporate secrets or account updates and notices – without regard for security. Why? Mainly it’s because they don’t know better, or they don’t know how to address the issue. […]

In the first installment of this tutorial series, you discovered that WPA-Enterprise encryption is the way to go if you desire a bulletproof Wi-Fi network. You also found out a few ways you can go about setting up this encryption method for your small or home office network. This tutorial will continue by introducing you […]

It’s not a secret that the WEP (Wired Equivalent Privacy) encryption method for wireless networks can be easily cracked. Using WEP actually invites Wi-Fi eavesdroppers to take a stab at cracking your encryption key, so they can connect to your network in order to steal data and wreak havoc. This leaves you with using the […]
