What you'll learn

Security can feel like a pile of arbitrary rules, and when controls don't make sense, people work around them, opening exactly the gaps attackers look for. In this course, Cyber Protections Explained, you'll gain the ability to see everyday security controls as one deliberate, layered system of defense. First, you'll explore why protection is built in layers, where each control catches what the others miss, so no safeguard has to be perfect. Next, you'll discover the main categories of protection, from physical, network, operating system, and software safeguards to the encryption and backups that keep data confidential and available. Finally, you'll learn how to recognize how authentication, authorization, and least privilege limit who can do what and contain the damage when something goes wrong. When you're finished with this course, you'll have the skills and knowledge of layered cyber protection needed to understand and confidently operate the security controls you meet at work and at home.
