AWS Serverless Security: Essential Best Practices for Developers

Securing modern cloud applications requires moving beyond traditional network perimeters. For developers building on AWS, understanding how to protect serverless architectures is critical to preventing data leaks and unauthorized access. This text-based course guides you from serverless security fundamentals to practical implementation. You will learn how to design, configure, and maintain highly secure serverless environments using industry-standard patterns and modern zero-trust strategies. What you'll learn: Understand core serverless security concepts, threat models, and the shared responsibility model; Configure AWS Lambda functions with strict least-privilege IAM roles and permission boundaries; Implement robust data protection using S3 bucket policies, KMS encryption, and AWS Secrets Manager; Apply network isolation strategies and API Gateway security controls to protect your endpoints; Set up comprehensive logging, monitoring, and auditing using CloudWatch and CloudTrail; Integrate automated security scanning into your modern CI/CD deployment pipelines. You will begin by learning essential security terminology and foundational cloud concepts. From there, you will progress through structured text-based lessons and practical scenarios that demonstrate how to secure code, data, and infrastructure step-by-step. This course is designed for software developers, cloud beginners, and aspiring security engineers. No prior cloud security experience is required, though a basic familiarity with cloud concepts is helpful.
