Tips for hot spot security

Comfortable? Enjoying your coffee at the corner café while watching the world go by? And so you should, it’s a lovely day outside. You’ve even got your notebook on the table, finishing some work; life is good.  But what about the guy up the back? Think he’s also enjoying a large decaf while working out of the office? No, he’s actually enjoying himself looking at the websites you’re visiting and busily searching your notebook and taking everything he’s interested in. Public place vs. private property it may sound far-fetched, but this happens every day to people using unprotected public Wi-Fi networks. While the wireless network at your home or business is (hopefully always) protected by decent levels of encryption using WPA or WPA2 (Wi-Fi Protected Access) certified programs, many public Wi-Fi hot spots do not provide such basic security. But why is encryption so important?

Chicken Soup for the Soul

The day will come when, after harnessing space, the winds, the tides and gravitation, we shall harness for God the energies of love. And on that day, for the second time in the history of the world, we shall have discovered fire.
