Question

5. (4 pts) When using WPA2 security on your wireless router with a pre-shared key (personal mode), can clients who are authorized to connect to the network (because they have the key) eavesdrop on each other’s traffic? Why or why not? Please provide sufficient technical detail to show your understanding.

Answer 1

Answer to the question is, can we eavesdrop on other users traffic.

Yes using some tools like wireshark, but can we make any use of it, then No.

What happens when we enter the password for authentication,is that we have a TCP like handshake between the decide and let's say the WiFi.

Now the next step in this handshake is a encryption standard, which even if common for all devices will have different keys for each connection.

Now let's say we have received enough to get all the data released by the WiFi but we just have the key for the data we were send,so we can eavesdrop on the traffic but we'll not be able to do anything with the encrypted data we can observe, so it's safe afterall.

There are other pitfalls of WPA2 but those doesn't come in plan here, hope it helps and if you need more details ask in comments.
