SSL/TLS is probably the most widely used security protocol on the internet. Since heartbleed was discovered a few years back, this protocol has been constantly audited and evaluated by security researchers around the world. TLS 1.3 is the latest version of the protcol designed from ground up to be more secure than its previous versions. This talk discusses new features and security improvements in TLS 1.3.


We will talk about what SSL/TLS is, why it is important for the internet. Then take a brief look at few of the security flaws in the protocol over the years. The finally look at security and performance improvements in TLS 1.3. Lastly why should this affect you as a systems engineer, system administrator, developer or even as a normal user.


Basic understanding of how protocols work, basic understanding of cryptography.
