AWS Systems Manager: Secure SSH Access to EC2 Instances

Traditional SSH access requires exposing your servers to the public internet, leaving them vulnerable to constant brute-force attacks. This text-only course teaches you how to transition to a secure, modern access model using AWS Systems Manager Session Manager. You will learn how to configure private connections to EC2 instances without bastion hosts, public IP addresses, or open inbound ports. What you'll learn: - Understand the foundational concepts of cloud network security and traditional SSH vulnerabilities. - Configure AWS Systems Manager Session Manager to enable secure shell access without open inbound ports. - Set up private subnets, NAT Gateways, and VPC Endpoints to restrict direct internet exposure. - Apply IAM policies and roles to enforce the principle of least privilege for instance management. - Audit and log session activity using CloudWatch and S3 for security compliance. The course starts with essential cloud networking and security definitions before guiding you through secure configuration scenarios. You will read conceptual explanations, study secure architecture patterns, and analyze policy code snippets to build a robust access control setup. This program is designed for beginner systems administrators, cloud security enthusiasts, and developers looking to secure their cloud infrastructure with no advanced prerequisites required.
