Open access for all users

hi all, am new here. I would like to know the problems that may arise when talking about open access to a wireless network and what are the recommendation that can be proposed to counteract. Also wanna know how access to the wireless network should be set up and run and the reasons for such proposal?

if you leave your wireless access point OPEN for all users, it means anyone in the local vicinity to you with a wireless capable device (notebook etc), can connect to your access point and use your local network/internet connection without your knowledge..

easiest method to secure your wireless access point is to setup WEP encryption at 64bits and assign your phone number as the password (10digits long) that way when you connect your machines to the access point and are prompted for hte password you wont need to remember the long Hexadecimal password it creates..

that way the only way you can connect is if you know that the password for the access point is your phone number.. and you'll be secure..

An open access point is a massive business risk.  Any information sent wirelessly can be captured, and even modified.  Any passwords that are sent in plain text can also be captured - you are also allowing external parties unmonitored access to your internal network.

While WEP provides a little more security I still wouldn't recommend it.  Data can be captured from a WEP connection, ultimately allowing the key to be cracked and allowing third parties to connect to your network.  WEP also stands for Wired Equivalent Privacy...the security provided by WEP is similar to that provided through the use of a Hub....any traffic on a WEP network can be sniffed by anyone connected to the network.....

I strongly recommend doing a Google search for "cracking WEP" - you will find a plethora of sites detailing the methods used to do this, and illustrating how easy this is to do with a few freely available tools.

The other risk associated with using an open network is that attackers could use your network to their own ends - installing rootkits and viruses on connected machines, spamming through your network or hosting or downloading illegal files....In short it's not just a risk to your data, but also the potential misuse of your network resources and bandwidth for illegal or immoral purposes.

I would consider WPA/WPA2 PSK security if your Access Point and Clients support it.  Never use a dictionary password and try to use a combination of upper case and lower case letters, numbers and ASCII characters...

Hope this helps

Assuming you talk about an enterpise network you should prefer WPA + EAP.
WPA encrypts your data, preventing sniffing and unauthorized reveal.

EAP will allo users to authenticate , for example against your Active Directory or LDAP.
EAP strenght is based on password strenght

For medium size bussiness WPA PSK (Preshare Key) is more than enough (and usually recommended)
