AWS EC2 Networking and Security Groups for Beginners

Securing your cloud infrastructure starts with understanding how network traffic flows to and from your virtual servers. Managing access through security groups is a fundamental skill for anyone working with cloud environments today. This text-based course guides you from cloud networking basics to confidently configuring secure, restricted access for your EC2 instances. You will transition from relying on default settings to implementing precise, least-privilege security configurations using both the management console and the AWS CLI. What you'll learn: - Understand core cloud networking concepts, including VPCs, subnets, and the differences between stateful and stateless firewalls - Create and configure EC2 security groups to control SSH, HTTP, and HTTPS traffic - Apply the principle of least privilege to restrict inbound and outbound traffic to specific IP ranges - Use the AWS CLI to automate security group creation, rule updates, and auditing - Implement modern zero-trust security concepts to minimize your cloud attack surface - Monitor network traffic patterns and troubleshoot connectivity issues using VPC Flow Logs The course begins with essential networking terminology and foundational security principles. You will then progress to practical configuration scenarios, learning to write secure rules step-by-step and automate your setup using command-line tools. This course is designed for aspiring cloud administrators, developers, and IT beginners who want to build a solid foundation in cloud security without needing prior networking experience.
