[Safety continued from page 1] While it is possible to make a wireless network as secure, if not more so, than a wired network, these steps are very rarely taken, which is the first and main downfall to wireless. It’s a new technology to most users, and many aren’t aware of how to properly |

| implement a wireless network. The main thing about wireless is that if you don’t take steps to validate users on the network, as well as encrypt the transmissions with a network key, the information is in the open air, with anyone within a range of up to a block or so, with a wireless card, could potentially enter your network, browse your shared documents, capture passwords, even install software just to name a few. “War driving” is the name that has been given to this practice, even some larger businesses have fallen prey to hackers with laptops, driving around outside, infiltrating company information.
How can this wireless be made 100% safe? Well there is no 100% |
fool proof way to make your wireless network secure, but this holds to wired networks as well. However, we can take some steps to drastically reduce this risk.
First, enable an encryption protocol on the network (1a). There are two main types, WEP and WPA (1b). WEP is 5 groups of 2 hex characters (64-bit), while WPA is 13 groups of 2(128 bit), which makes WPA a better encryption, but not all devices support this yet. After you choose and encryption method, you make a pass phrase to generate the key. (1c) Based on the pass phrase u choose, a set of network keys are generated. (1d) What these do is run all network traffic through an encryption key |
