These techniques describe how to test wireless networks for security holes. It is very important to check if your network is vulnerable.

Check if the network has some form of security

If you can connect to the access point without any trouble, the network is not secured. Check the instructions at #Security your network.

Install security related software

First, you need to install some tools. Execute the following command in the terminal application:

 sudo yum install wireshark kismet aircrack-ng nessus bind-utils traceroute

yum install wireshark_gnome
