We all have gaps in our security knowledge. Fireside Fridays will be an opportunity to fill in those gaps. Each Friday we will pick a topic and go over the basics. These sessions will be a combination of lecture and hands on labs. We’ll cover a single topic and hopefully fill in some of those cracks. Think of it as a single focused “ask us anything” session. No judgment on the questions that get asked, just a chance to raise the bar for all of us.

In this Fireside we’ll deep dive into packet filtering firewalls as well as proxies. We will also discuss Network Address Translation (NAT) and how it works.
