Protecting your digital identity, passwords, and browsing activity is difficult in the world of open Wifi networks, freeware, and advanced advertising techniques based on tracking users across the web. While complete privacy is not possible while connected to the internet, there are many things you can do to make access to your personal data more difficult. This presentation will focus on the basics of internet security, how to begin protecting your network and your data, and why it’s so important. We will focus on the two most prominent (and easiest to fix) security vulnerabilities: encrypting your browsing on external networks using OpenVPN, and blocking advertising and tracking as early as possible using Pi-Hole.
