Mozilla recently observed over 50% of web traffic to Firefox users using SSL. With efforts like Let's Encrypt offering free and easy to deploy certificates, and increased user awareness regarding mass surveillance, the trend to encrypted traffic and dark networks will only increase. But this doesn't imply that one has to throw in the towel and stop watching network traffic. Even encrypted traffic still offers significant information that can be used to help secure your network. You will learn which information can be extracted from encrypted TLS traffic, how to intercept and in some cases decrypt TLS encrypted traffic and how to balance the security advantages of encryption with the need to inspect network traffic to limit data exfoliation threats.
