Wireless Network Safety

There is no doubt that wireless internet has increased productivity and improved communications. Users can join wireless networks at school, in airports and hotels, and even restaurants. However wireless connections may not always be safe. Many public Wi-Fi spots are not secured and users are at risk of exposing sensitive information and data.

Unsecured Wi-Fi

The information you send over an unsecured Wi-Fi network is not encrypted. Always keep that in mind when deciding what information you are sending. A user should always know what network you are joining. In an Evil Twin attack, a user is tricked into joining an impostor network that mimics the authentic public access network. Once the user joins, the attacker can easily intercept sensitive information.

Weak Security Wi-Fi

Some Wi-Fi networks are secured with the Wireless Equivalent Privacy (WEP), a networking standard. Its intention was to provide encryption of your network traffic. This proved to be too weak of a standard and allowed for very quick and efficient cracking of network traffic. Many old Wi-Fi networks still use this standard and any connection using WEP should be done as if it is an unsecured Wi-Fi. WEP has been replaced with Wi-Fi Protected Access II (WPA2) and should be the preferred for wireless networks.


  • You should disable shared folders.
  • You should always restrict email use.
  • Be cautious about the wireless network you join.
  • Data sent through a insecure Wi-Fi network is sent in the clear and can be intercepted.
  • Be careful about what information you are sending.
  • You should never send personnel information such as a user id, password, banking information, or credit card numbers.
