DevSecOps Essentials: Securing Web Apps with AWS WAF and CloudWatch

Web applications are constant targets for cyber attacks, making security a fundamental requirement for modern developers and DevOps engineers. Understanding how to defend your infrastructure using cloud-native tools is essential for safeguarding sensitive data and maintaining application uptime. In this course, you will transition from basic web development to implementing robust DevSecOps security practices. You will learn how to build defensive application layers, configure cloud firewalls, and analyze system events to detect and mitigate malicious activity before it impacts your users. What you'll learn: - Understand foundational web security principles, the modern threat landscape, and the role of DevSecOps in cloud environments. - Configure AWS WAF using managed rules, custom IP lists, and rate-limiting to block common web exploits. - Implement structured logging and custom exception handling within web applications to turn application logs into security assets. - Monitor traffic patterns and detect anomalous behavior using CloudWatch filters, alarms, and dashboards. - Analyze security logs using Athena and Excel to perform post-incident threat analysis and identify attack vectors. The journey begins with fundamental security definitions and concepts before moving into practical implementation. You will read through step-by-step guidance on setting up basic application logging, deploying security rules on AWS, and analyzing simulated attack traffic to see your defenses in action. This text-based course is designed for beginners, developers, and aspiring DevOps engineers who want to build a solid foundation in cloud security. No prior security experience is required, though basic familiarity with web concepts is helpful. Start reading today to build stronger, more resilient web applications on AWS.
