In this lesson, we will explore the common concepts in cybersecurity and the specialized terminology its professionals use. We will dive into cryptography by defining and showing examples and how it is used. Next, we will explore why obfuscation is important in cybersecurity and the differences between threats and vulnerabilities. Smart businesses have a plan for when attacks happen, so we will look at Incident Response Plans, how they are created, and what they should contain. Finally, we will examine Identity and Access Management (IAM) and the IAM framework—authentication, authorization, and accounting.
