Securing Internal APIs with AWS API Gateway Private Endpoints
Overview In a modern AWS environment, Application Programming Interfaces (APIs) are the connective tissue for microservices and data access. However, not all APIs are meant for public consumption. A common and significant security risk is the exposure of internal-facing APIs to the public internet, creating an unnecessary attack surface. The ideal configuration for these internal […]
Managing Cross-Account Access in AWS API Gateway
Overview In a modern AWS architecture, Amazon API Gateway often acts as the primary entry point for applications, managing access to backend services and business logic. As organizations scale and adopt multi-account strategies for different environments or business units, enabling cross-account API access becomes a necessity. However, misconfiguring these access controls is a common and […]
Mastering API Gateway Observability: A FinOps Guide to Detailed CloudWatch Metrics
Overview Amazon API Gateway is the front door to modern applications on AWS, managing traffic for backend services. However, by default, its monitoring capabilities provide a high-level, aggregated view of performance. This creates significant observability gaps, where the health of the overall API can mask critical failures or security threats occurring on specific endpoints. Without […]
Securing AWS API Gateway with IP-Based Access Controls
Overview In the AWS ecosystem, Amazon API Gateway acts as the front door for applications, managing traffic between end-users and backend services like AWS Lambda or Amazon EC2. By default, these gateways are publicly accessible, creating a significant attack surface that can be targeted by malicious actors. Leaving this front door open to the entire […]
AWS API Gateway Security: Managing Client Certificate Rotation
Overview In modern AWS architectures, Amazon API Gateway is the central entry point for accessing backend services, data, and business logic. While teams often focus on securing client-facing connections, the security of the “back door”—the connection between API Gateway and its integration endpoints—is just as critical for service reliability and integrity. A primary method for […]
