In this course, six videos take you through the essentials of secure network design. From firewalls and the so-called demilitarized zone (DMZ) to honeypots, honeytokens and honeynets, endpoint security and the many flavors of authentication protocol, learn to identify the potential chinks in a system’s armor — and how to make them secure.
