In the initial stages of a project, developers often prioritize rapid development by placing servers and databases in public subnets, allowing easy access for debugging. However, this method poses significant security risks as sensitive data becomes vulnerable to unauthorized internet access. While some mitigate this by restricting access through VPC security groups, this approach is flawed due to indiscriminate access within shared office IPs and challenges for remote workers. To enhance both security and accessibility, AWS Systems Manager offers a solution by enabling secure access to AWS resources in private subnets without exposing them publicly. Users can exchange AWS credentials for temporary access to EC2 instances, and by setting up a bastion host in a VPC, they can access databases like RDS and ElastiCache indirectly. Through SSH tunnels, users can connect to these resources as if they were local, allowing secure access without compromising security by exposing infrastructures to the internet. This approach resolves the common problem of balancing security and access, especially in remote work environments, while preventing unauthorized users from accessing critical systems.
