Modern TLS
2025-09-25 , A211

Transport Layer Security is one of the least well-understood parts of system administration. This tutorial will take you into a deep dive into the management of TLS. We'll discuss:

-how TLS Works
-what TLS provides, and what it doesn't
-assessing TLS configurations
-the ACME protocol and Let's Encrypt
-OCSP and Certificate Revocation
-CAA, HSTS, and Certificate Transparency
-debugging TLS

You'll leave with the understanding of TLS that every sysadmin should have.
