If you don't have permission, breaking into someone else's network is illegal regardless of why you're doing so. If you really want to learn about the security vulnerabilities of WPA-PSK and WEP, I recommend setting up your own AP and practice breaking into it.


There are several ways to view who's on your network, some easier/less technical than others: The logging feature in your router; Sometimes you can view currently connected devices. For example in a FritzBox you can see all devices that have a dhcp lease (i.e. which got an IP address) on the "Home Network" page. You could scan the network from your laptop ...


I assume the question is about the "server" certificates used by PEAP, EAP-TLS, and EAP-TTLS to protect password authentication, as this wouldn't be a problem at all with client-certificate-based EAP-TLS. I doubt the EAP standards documents would ever have this information, given the crazy inconsistency across implementations (which surely wouldn't be as ...


Yes. Pretty straight forward information provided by each wireless access point. For instance in Android, this is what this information looks like in Wifi Analyzer: Only the security types listed for an access point will be accepted.


Yes, ofcourse that is possible! Almost any device that can wirelessly connect using WiFi, also has an interface for connecting to it right? I'm pretty sure that almost ALL devices, when prompted for a password say something like: "This network is using WPA2 Protection, please enter your password" or: "This network is useng an Enterprise Security, ...


In the scenario you have outlined it is in fact possible, at least in theory, to sniff the connection. Okay, so WEP is easy to crack, and if you are using, you should stop and get on to WPA2, which is far more secure, and nearly impossible to break. In each of these cases you will need to have some sort of password/key set up. If it's just your own access ...


Check your router/AP documentation for a logging option. Turn it on if it's off, and look at the logs. Do this every day for a week or so to develop an idea of what is "normal." Then look every week or so. After you've looked for a while, whether you spot an intruder or not, change the AP password.
