802.11 networks rely on encryption to ensure the security of all wireless traffic. In this video, you’ll learn about WEP and WPA encryption and the dangers of using the wrong encryption on your wireless network.
When a web server uses a single private key to encrypt all communication, then all communication can potentially be decrypted afterwards with this single bit of data. In this video, you’ll learn how perfect forward secrecy can be used to create encryption keys dynamically for every encrypted session.
