Case Study: Revealing Infrastructure Blind Spots Across Hybrid Enterprise Environments

Security Engagement Overview

Industry Profile

Global logistics firm with hybrid infrastructure—including on-prem servers, containerized applications, and multi-cloud deployments spanning AWS and Azure.

Assessment Scope

The client's transition to cloud-native operations introduced visibility gaps and left critical services exposed through outdated firewall rules and misconfigured IAM policies.

  • Unfiltered access from public IPs to cloud load balancers
  • Misconfigured S3 buckets and exposed secrets in CI/CD pipelines
  • Open internal ports on legacy VM instances accessible via VPN

Vulnerability Analysis

  • Perimeter Exposure: Load balancer routing rules allowed unauthenticated traffic to backend services bypassing WAF.
  • Cloud Misconfigurations: Multiple S3 buckets had “public read” permissions and exposed sensitive customer billing data.
  • Internal Pathways: VPN split-tunneling enabled lateral movement from low-trust devices into secure zones.

Mitigation Strategy

  • Implemented geo-based firewall rules and WAF access control for edge services
  • Audited and enforced bucket-level security policies via automated scanners
  • Replaced VPN with a zero-trust network access architecture using identity-aware proxies

Strategic Takeaways

  • Network segmentation must span clouds and physical infrastructure
  • Least privilege and continuous IAM policy audits are non-negotiable
  • Secrets management is critical within CI/CD pipelines
  • Threat modeling across data flows reveals paths traditional scanners miss
