In this course you will learn to understand the basic concepts and techniques of email and website encryption.
In the years following Snowden's disclosures, the importance of properly securing email communications and websites has become clear to everyone. Recently, the GDPR rules have also helped to focus on the secure transmission of data.
The course will first focus on the concept of threat models in IT security, for example: What are we protecting, which attacks are we protecting against, and what is the consequence if it did not succeed?
Afterwards we look at the technique concerning history and concepts in encryption and explain the concepts PKI and TLS.
Finally, we will discuss how TLS is used in HTTPS for securing websites and in SMTP / IMAP for securing email.
It is recommendable to take our course in DNSSEC in connection with this course.
Thomas Steen Rasmussen works for internet provider BornFiber as Unix administrator/security manager/developer. He also runs his own one-man business – tyktech. He is involved in the DNS censorship service and similar internet activist projects.
