Chapter 11. Wireless Packet Analysis > Wireless Security
11.8. Wireless Security
The biggest concern when deploying and administering a wireless network is the security of the data transmitted across it. With data flying through the air, free for the taking by anyone who knows how, it’s crucial that data be encrypted. Otherwise, anyone with Wireshark and an AirPcap card can see it.
Note:
When another layer of encryption, such as SSL or SSH, is used, traffic will still be encrypted at that layer, and the user’s communication will still be unreadable by a person with a packet sniffer.
