In the second part of the guide on securing AWS pipelines, the focus shifts to integrating VPC for enhanced security measures.
A VPC (Virtual Private Cloud) creates an isolated section in AWS to securely launch and manage resources, ensuring controlled access and protection from security risks.
Securing access to private resources in a VPC involves connecting the pipeline to a production environment in a private subnet.
Private subnets, without direct internet access, require a NAT Gateway or VPC Endpoint for secure deployment and outbound traffic control.
Security Group Rules, IAM Roles, and Policies are essential components to regulate access and prevent unauthorized changes within the VPC.
By using a NAT Gateway in a private subnet, applications can securely access the internet for updates while maintaining a shield against security threats.
A step-by-step Terraform template is provided to create and configure a VPC, public and private subnets, NAT Gateway, route tables, and Security Groups for enhanced security.
This setup ensures that the CICD pipeline can deploy updates to resources in a private subnet with controlled internet access via the NAT Gateway, enhancing security measures.
