Wireless Network Security II
We browse the internet and have far fetching concerns of how secure our connection is, especially when its wireless. Here are a few pointers:
The security concerns with wireless network centre around :
The authentication component (pre-shared keys) of schemes such as WPA and WEP, as well as MAC address filtering, address the issue of restricting access to the wireless network to only authorized devices.
Encryption address the issue of protecting against eavesdropping on the wireless network traffic.
If you turn off WPA (or similar scheme), you are turning off an access control method as well as an encryption method. The wireless network traffic can then be easily eavesdropped on, and the MAC addresses and IP addresses of participating machines can be determined. These can then be spoofed, and the wireless network joined.
Turn back on WPA/WPA2.
Other way to prevent unauthorized network access are
1. Password-protect your wireless connection. Turn on WEP (wired equivalency privacy) or WPA (Wi-Fi protected access) on all of your devices, including your router, your media center. You may also set up a security key for your wireless network.
2. Place the wireless access point away from windows and near the center of your house to decrease the signal strength outside of the intended coverage area.
3. Keep all software current (including your Web browser) with automatic updates. Use firewall, antivirus, antispam, and antispyware software from a source that you trust and watch out for fake alerts for security software.
