AWS Network Security: Securing Public Subnets with HTTPS

Publicly accessible cloud instances are prime targets for security threats if left unprotected. Securing your network entry points is the first and most critical line of defense for any cloud deployment. This course guides you through securing your public subnets by restricting access to HTTPS traffic. You will learn to isolate your backend resources, configure secure routing, and leverage load balancers to establish a robust and modern network security posture. What you'll learn: Understand foundational cloud networking concepts, including subnets, route tables, and internet gateways; Configure Security Groups and Network Access Control Lists using modern least-privilege principles; Deploy Application Load Balancers to safely route external HTTPS traffic to private backend instances; Implement SSL/TLS certificates to encrypt data in transit and ensure secure communication; Monitor network traffic and audit security configurations using modern logging tools. You will begin with core networking definitions and security fundamentals before moving step-by-step through configuring secure public-facing architectures. Through written explanations and practical configuration examples, you will build a solid foundation in cloud security. This course is designed for beginners in cloud administration, system operations, and security, with no prior advanced networking experience required.
