Kong utilizes a suite of tools including HashiCorp's Terraform and AWS GuardDuty to enhance security and automate infrastructure management through Infrastructure as Code (IaC). GuardDuty, a continuous monitoring service, detects security threats by analyzing events from CloudTrail, VPC Flow Logs, and DNS logs using machine learning and anomaly detection. It aggregates findings across multiple AWS accounts into a master account for centralized management, allowing threats to be detected and addressed efficiently. To facilitate quick responses, Kong configures GuardDuty to send notifications to CloudWatch Events, which then trigger a Lambda function called GuardDuty2Slack to alert the security team via Slack. The setup process, detailed in the text, involves creating IAM roles and configuring Terraform scripts to manage accounts and regions, ensuring comprehensive threat detection and automated notifications. The post provides a step-by-step guide for implementing these configurations and includes code examples to integrate member accounts and enable Slack notifications for detected threats.
