Описание: Preparing for your AWS certification? If you're dealing with data in the cloud, you absolutely need to master encryption. In this video, we dive deep into the AWS Key Management Service (KMS), a fundamental service for cloud security that is guaranteed to show up on your exams.

We break down the complex architectural puzzle of managing millions of encryption keys without ever exposing them. From the physical security of Hardware Security Modules (HSMs) to the logic of Key Policies, this guide covers everything you need to know to answer KMS questions correctly.

In this video, you will learn:

The Architecture: How KMS acts as a secure digital vault using FIPS 140-2 validated hardware.

Key Types: The critical differences between Customer Managed Keys (CMKs) and AWS Managed Keys—and when to use which for the exam.

Envelope Encryption: The "magic" pattern AWS uses to protect data at scale efficiently.

Access Control: Why Key Policies are the "law of the land" and how they interact with IAM policies.
