About this course

Securing cloud infrastructure and sensitive data is a critical requirement for any modern organization operating in AWS. Without proper protection, credentials, API keys, and server access are vulnerable to unauthorized exposure. This written course guides you through the fundamental principles of AWS security, teaching you how to safeguard infrastructure and manage sensitive data. You will gain a clear understanding of key management, secure parameter storage, and secrets lifecycle management to keep your cloud environment secure. What you'll learn: 1. Understand foundational AWS security concepts, including zero-trust architecture and credential management. 2. Configure and manage EC2 key pairs to establish secure connections to cloud instances. 3. Store and retrieve configuration data safely using AWS Systems Manager Parameter Store. 4. Secure sensitive API keys and database credentials with AWS Secrets Manager. 5. Apply modern security best practices, including credential rotation and access control principles. You will start by exploring core cloud security terminology and foundational concepts before moving on to step-by-step written explanations for configuring key pairs, managing parameters, and securing secrets. This course is designed for beginners who are new to cloud security and AWS, requiring no prior experience in infrastructure protection. Start reading today to build a strong foundation in protecting cloud data and infrastructure.
