SoftPerfect WiFi Guard is an essential tool for everyone running a small wireless network and striving to keep it secure. Generally, modern Wi-Fi networks are well protected, but there are a number of weaknesses that can compromise your Wi-Fi password; this includes vulnerabilities in encryption and brute force attacks. As a result, someone can gain unauthorised access to your Internet connection and LAN and exploit them while staying unnoticed.
Here comes our little application: it will alert you if your network is used without your knowledge. WiFi Guard is a specialised network scanner that runs through your network at set intervals and reports immediately if it has found any new, unknown or unrecognised connected devices that could possibly belong to an intruder.
- Pings computers and other network devices and displays those alive.
- Detects firewalled computers that do not respond to ping.
- Scans your network at a specified interval.
- Immediately alerts you if an unknown device is found.

WEP vs. WPA vs. WPA2 Comparison
How do Wifi wireless get hacked? With the right software such as Air Crack or Backtrack, one can easily break any WEP encryption keys. What AirCrack does is it gathers all the data transmitted between your router and your devices, compiles it and then computes all the possible combinations. With today’s processing power and the weakness in WEP, it takes less than 10 minutes to reveal your WEP security key on a busy network.

WPA has its own weakness too, but it is harder to crack. WPA2 is highly recommended for SME or enterprise; remember than anything man made can be unmade. WPA2 is crackable too, but it will require too much effort and time. It is easier for the hacker to look for someone using WEP instead of wasting time breaking the WPA2 security code. Below is a simple side by side comparison between WEP, WPA and WPA2.
