You often hear that one of the first steps is to harden your servers and services - buy how exactly do you do that?
In this workshop, we will go through the various stages of hardening a Linux environment (Ubuntu) against attackers. During this workshop, we will consider common attack vectors and their mitigations, deploying security "feelers" and properly configuring the operating system and services against attacks.
This is an introductory level workshop (2-6 hours), hands-on, that allows participants to practice basic security hardening steps and customize their journey from that launch point.
