Keeping Your Ubuntu Systems Secure
Ubuntu is well-known for being a secure system by default, but there are things you can do (and not do!) to make sure that it stays safe. This talk will cover everything from staying on top of security updates to encrypting your hard drive and understanding how to safely use Personal Package Archives (PPA) packages. You'll also learn how the Ubuntu Firewall (UFW) works and how services like this can also protect a server running Ubuntu.
