Secure AWS Infrastructure

---

Requirement | Security features

The client required a security layer for their existing AWS infrastructure to protect internal workloads and internet-exposed resources. They needed assurance that their AWS environment adhered to best practices and minimized security breach risk.

Solution | Security framework

We implemented AWS native solutions to achieve a high security posture without additional licensing. First, we enabled AWS Single Sign-On (SSO) via IAM Identity Center to centralize user access control. We deployed AWS Config, AWS GuardDuty, AWS CloudTrail, and AWS Security Hub to provide continuous visibility into potential issues, security vulnerabilities, and a full audit trail of configuration changes.

We enforced network segmentation using AWS Network Firewall and isolated workloads across multiple VPCs following best-practice designs. For EC2 instances and container workloads, we configured AWS Inspector and container image scanning to identify and manage code vulnerabilities. We implemented AWS WAF rules and AWS Shield protection for internet-facing applications. We also established mutual TLS authentication for secure service-to-service communication and automated remediation actions via AWS Lambda.

Outcome | Increased level of security

The client now maintains a security framework aligned with AWS best practices and gains centralized visibility into their security posture. The solution delivers enhanced protection against cyber threats and streamlines security management for their small operations team through automated remediation.
