I am network administrator and I am always worried about network security as I know people use different techniques of hacking to penetrate wireless and wired networks. Recently I came to about software called Feedingbottle which can hack WEP on finger tips; you don't even have to know anything about networking and hacking as its just a simple GUI.
I am interested in knowing how this works and what we can do to avoid this. I'm also interested in knowing if there are any other tools available that can do this.
I know about Aircrack, but in order to use it you should have some knowledge about how it works. I know hacking WPA is really difficult and although most default passwords giving by ISP's are sometimes hackable, but if you change the password and use WPA or WPA2 it is nearly unhackable if the password is good.
Is this correct? If not, how can I avoid having my passwords hacked?
