AWS Lambda for Front-End Engineers: Managing Security Headers

Modern front-end development requires more than just building responsive user interfaces; securing your application at the delivery layer is crucial for protecting user data. Many web developers struggle with configuring server-level security settings when deploying to serverless platforms. This text-based course guides you through configuring and deploying custom security headers using AWS Lambda and CloudFront. You will learn how to analyze your site's security posture, write lightweight edge functions, and implement modern headers that shield your web applications from common vulnerabilities. What you'll learn: 1. Understand the core concepts of web security headers, including CSP, HSTS, and referrer policies. 2. Analyze your website's security posture using industry-standard header assessment tools. 3. Write AWS Lambda functions to intercept and modify viewer responses at the edge. 4. Compare CloudFront Functions and Lambda@Edge to choose the right tool for your latency needs. 5. Deploy and test your header modifications safely within an AWS infrastructure. 6. Apply best practices for ongoing security monitoring and header maintenance. You will start with foundational web security terminology and header specifications before moving on to practical AWS configurations. Step-by-step written walkthroughs show you how to write, deploy, and verify your custom Lambda functions in a production-ready environment. Designed for front-end engineers and web developers who want to take control of their application security, this course requires no prior AWS experience.
